Internally, +QTextEdit uses the QTextDocument class to describe both the high-level +structure of each document and the low-level formatting of paragraphs. + +If you are viewing this document in the textedit example, you can edit this +document to explore Qt's rich text editing features. We have included some +comments in each of the following sections to encourage you to experiment. + +## Font and Paragraph Styles + +QTextEdit supports **bold**, *italic*, _underline_ & ~~strikethrough~~ font +styles, and can display +<span style="font-size:10pt; font-weight:600; color:#00007f;"> multicolored</span> +text. Font families such as +<span style="font-family:Times New Roman">Times New Roman</span> and +<span style="font-family:Courier">Courier</span> +can also be used directly. *If you place the cursor in a region of styled text, +the controls in the tool bars will change to reflect the current style.* + +Paragraphs can be formatted so that the text is left-aligned, right-aligned, +centered, or fully justified. + +*Try changing the alignment of some text and resize the editor to see how the +text layout changes.* + +## Lists + +Different kinds of lists can be included in rich text documents. Standard +bullet lists can be nested, using different symbols for each level of the list: + +- Disc symbols are typically used for top-level list items. + * Circle symbols can be used to distinguish between items in lower-level + lists. + + Square symbols provide a reasonable alternative to discs and circles. + +Ordered lists can be created that can be used for tables of contents. Different +characters can be used to enumerate items, and we can use both Roman and Arabic +numerals in the same list structure: + +1. Introduction +2. Qt Tools + 1) Qt Assistant + 2) Qt Designer + 1. Form Editor + 2. Component Architecture + 3) Qt Linguist + +The list will automatically be renumbered if you add or remove items. *Try +adding new sections to the above list or removing existing item to see the +numbers change.* + +Task lists can be used to track progress on projects: + +- [ ] This is not yet done +- This is just a bullet point +- [x] This is done + +## Images + +Inline images are treated like ordinary ranges of characters in the text +editor, so they flow with the surrounding text. Images can also be selected in +the same way as text, making it easy to cut, copy, and paste them. + + *Try to select this image by clicking and +dragging over it with the mouse, or use the text cursor to select it by holding +down Shift and using the arrow keys. You can then cut or copy it, and paste it +into different parts of this document.* + +## Tables + +QTextEdit can arrange and format tables, supporting features such as row and +column spans, text formatting within cells, and size constraints for columns. + +| | Development Tools | Programming Techniques | Graphical User Interfaces | +| ------------: | ----------------- | ---------------------- | ------------------------- | +| 9:00 - 11:00 | Introduction to Qt ||| +| 11:00 - 13:00 | Using qmake | Object-oriented Programming | Layouts in Qt | +| 13:00 - 15:00 | Qt Designer Tutorial | Extreme Programming | Writing Custom Styles | +| 15:00 - 17:00 | Qt Linguist and Internationalization | | | + +*Try adding text to the cells in the table and experiment with the alignment of +the paragraphs.* + +## Hyperlinks + +QTextEdit is designed to support hyperlinks between documents, and this feature +is used extensively in +[Qt Assistant](http://doc.qt.io/qt-5/qtassistant-index.html).

fully-fledged modern GUI application, it uses many of the basic + elements that are used in more complex applications. After you + have worked through this tutorial, we recommend reading the + \l{mainwindows/application}{Application} example, which presents a + small GUI application, with menus, toolbars, a status bar, and so + on. +*/ + +/*! + \example tutorials/addressbook/part1 + \title Part 1 - Designing the User Interface + \brief Describes how to code the user interface of the Address Book Example. + This first part covers the design of the basic graphical user + interface (GUI) for our address book application. + + The first step in creating a GUI program is to design the user + interface. Here the our goal is to set up the labels and input + fields to implement a basic address book. The figure below is a + screenshot of the expected output. + + \image addressbook-tutorial-part1-screenshot.png + + We require two QLabel objects, \c nameLabel and \c addressLabel, as well + as two input fields, a QLineEdit object, \c nameLine, and a QTextEdit + object, \c addressText, to enable the user to enter a contact's name and + address. The widgets used and their positions are shown in the figure + below. + + \image addressbook-tutorial-part1-labeled-screenshot.png + + There are three files used to implement this address book: + + \list + \li \c{addressbook.h} - the definition file for the \c AddressBook + class, + \li \c{addressbook.cpp} - the implementation file for the + \c AddressBook class, and + \li \c{main.cpp} - the file containing a \c main() function, with + an instance of \c AddressBook. + \endlist + + \section1 Qt Programming - Subclassing + + When writing Qt programs, we usually subclass Qt objects to add + functionality. This is one of the essential concepts behind creating + custom widgets or collections of standard widgets. Subclassing to + extend or change the behavior of a widget has the following advantages: + + \list + \li We can write implementations of virtual or pure virtual functions to + obtain exactly what we need, falling back on the base class's implementation + when necessary. + \li It allows us to encapsulate parts of the user interface within a class, + so that the other parts of the application don't need to know about the + individual widgets in the user interface. + \li The subclass can be used to create multiple custom widgets in the same + application or library, and the code for the subclass can be reused in other + projects. + \endlist + + Since Qt does not provide a specific address book widget, we subclass a + standard Qt widget class and add features to it. The \c AddressBook class + we create in this tutorial can be reused in situations where a basic address + book widget is needed. + + \section1 Defining the AddressBook Class + + The \c{tutorials/addressbook/part1/addressbook.h} file is + used to define the \c AddressBook class. + + We start by defining \c AddressBook as a QWidget subclass and declaring + a constructor. We also use the Q_OBJECT macro to indicate that the class + uses internationalization and Qt's signals and slots features, even + if we do not use all of these features at this stage. + + \snippet tutorials/addressbook/part1/addressbook.h class definition + + The class holds declarations of \c nameLine and \c addressText, + the private instances of QLineEdit and QTextEdit mentioned + earlier. The data stored in \c nameLine and \c addressText will + be needed for many of the address book functions. + + We don't include declarations of the QLabel objects we will use + because we will not need to reference them once they have been + created. The way Qt tracks the ownership of objects is explained + in the next section. + + The Q_OBJECT macro itself implements some of the more advanced features of Qt. + For now, it is useful to think of the Q_OBJECT macro as a shortcut which allows + us to use the \l{QObject::}{tr()} and \l{QObject::}{connect()} functions. + + We have now completed the \c addressbook.h file and we move on to + implement the corresponding \c addressbook.cpp file. + + \section1 Implementing the AddressBook Class + + The constructor of \c AddressBook accepts a QWidget parameter, \a parent. + By convention, we pass this parameter to the base class's constructor. + This concept of ownership, where a parent can have one or more children, + is useful for grouping widgets in Qt. For example, if you delete a parent, + all of its children will be deleted as well. + + \snippet tutorials/addressbook/part1/addressbook.cpp constructor and input fields + + In this constructor, the QLabel objects \c nameLabel and \c + addressLabel are instantiated, as well as \c nameLine and \c + addressText. The \l{QObject::tr()}{tr()} function returns a + translated version of the string, if there is one + available. Otherwise it returns the string itself. This function + marks its QString parameter as one that should be translated into + other languages. It should be used wherever a translatable string + appears. + + When programming with Qt, it is useful to know how layouts work. + Qt provides three main layout classes: QHBoxLayout, QVBoxLayout + and QGridLayout to handle the positioning of widgets. + + \image addressbook-tutorial-part1-labeled-layout.png + + We use a QGridLayout to position our labels and input fields in a + structured manner. QGridLayout divides the available space into a grid and + places widgets in the cells we specify with row and column numbers. The + diagram above shows the layout cells and the position of our widgets, and + we specify this arrangement using the following code: + + \snippet tutorials/addressbook/part1/addressbook.cpp layout + + Notice that \c addressLabel is positioned using Qt::AlignTop as an + additional argument. This is to make sure it is not vertically centered in + cell (1,0). For a basic overview on Qt Layouts, refer to the + \l{Layout Management} documentation. + + In order to install the layout object onto the widget, we have to invoke + the widget's \l{QWidget::setLayout()}{setLayout()} function: + + \snippet tutorials/addressbook/part1/addressbook.cpp setting the layout + + Lastly, we set the widget's title to "Simple Address Book". + + \section1 Running the Application + + A separate file, \c main.cpp, is used for the \c main() function. Within + this function, we instantiate a QApplication object, \c app. QApplication + is responsible for various application-wide resources, such as the default + font and cursor, and for running an event loop. Hence, there is always one + QApplication object in every GUI application using Qt. + + \snippet tutorials/addressbook/part1/main.cpp main function + + We construct a new \c AddressBook widget on the stack and invoke + its \l{QWidget::show()}{show()} function to display it. + However, the widget will not be shown until the application's event loop + is started. We start the event loop by calling the application's + \l{QApplication::}{exec()} function; the result returned by this function + is used as the return value from the \c main() function. At this point, + it becomes apparent why we instantiated \c AddressBook on the stack: It + will now go out of scope. Therefore, \c AddressBook and all its child widgets + will be deleted, thus preventing memory leaks. +*/ + +/*! + \example tutorials/addressbook/part2 + \title Part 2 - Adding Addresses + \brief Describes the code for inserting records in the Address Book Example. + + The next step in creating the address book is to implement some + user interactions. + + \image addressbook-tutorial-part2-add-contact.png + + We will provide a push button that the user can click to add a new contact. + Also, some form of data structure is needed to store these contacts in an + organized way. + + \section1 Defining the AddressBook Class + + Now that we have the labels and input fields set up, we add push buttons to + complete the process of adding a contact. This means that our + \c addressbook.h file now has three QPushButton objects declared and three + corresponding public slots. + + \snippet tutorials/addressbook/part2/addressbook.h slots + + A slot is a function that responds to a particular signal. We will discuss + this concept in further detail when implementing the \c AddressBook class. + However, for an overview of Qt's signals and slots concept, you can refer + to the \l{Signals and Slots} document. + + Three QPushButton objects (\c addButton, \c submitButton, and + \c cancelButton) are now included in our private variable declarations, + along with \c nameLine and \c addressText. + + \snippet tutorials/addressbook/part2/addressbook.h pushbutton declaration + + We need a container to store our address book contacts, so that we can + traverse and display them. A QMap object, \c contacts, is used for this + purpose as it holds a key-value pair: the contact's name as the \e key, + and the contact's address as the \e{value}. + + \snippet tutorials/addressbook/part2/addressbook.h remaining private variables + + We also declare two private QString objects, \c oldName and \c oldAddress. + These objects are needed to hold the name and address of the contact that + was last displayed, before the user clicked \uicontrol Add. So, when the user clicks + \uicontrol Cancel, we can revert to displaying the details of the last contact. + + \section1 Implementing the AddressBook Class + + Within the constructor of \c AddressBook, we set the \c nameLine and + \c addressText to read-only, so that we can only display but not edit + existing contact details. + + \dots + \snippet tutorials/addressbook/part2/addressbook.cpp setting readonly 1 + \dots + \snippet tutorials/addressbook/part2/addressbook.cpp setting readonly 2 + + Then, we instantiate our push buttons: \c addButton, \c submitButton, and + \c cancelButton. + + \snippet tutorials/addressbook/part2/addressbook.cpp pushbutton declaration + + The \c addButton is displayed by invoking the \l{QPushButton::show()} + {show()} function, while the \c submitButton and \c cancelButton are + hidden by invoking \l{QPushButton::hide()}{hide()}. These two push + buttons will only be displayed when the user clicks \uicontrol Add and this is + handled by the \c addContact() function discussed below. + + \snippet tutorials/addressbook/part2/addressbook.cpp connecting signals and slots + + We connect the push buttons' \l{QPushButton::clicked()}{clicked()} signal + to their respective slots. The figure below illustrates this. + + \image addressbook-tutorial-part2-signals-and-slots.png + + Next, we arrange our push buttons neatly to the right of our address book + widget, using a QVBoxLayout to line them up vertically. + + \snippet tutorials/addressbook/part2/addressbook.cpp vertical layout + + The \l{QBoxLayout::addStretch()}{addStretch()} function is used to ensure + the push buttons are not evenly spaced, but arranged closer to the top of + the widget. The figure below shows the difference between using + \l{QBoxLayout::addStretch()}{addStretch()} and not using it. + + \image addressbook-tutorial-part2-stretch-effects.png + + We then add \c buttonLayout1 to \c mainLayout, using + \l{QGridLayout::addLayout()}{addLayout()}. This gives us nested layouts + as \c buttonLayout1 is now a child of \c mainLayout. + + \snippet tutorials/addressbook/part2/addressbook.cpp grid layout + + Our layout coordinates now look like this: + + \image addressbook-tutorial-part2-labeled-layout.png + + In the \c addContact() function, we store the last displayed contact + details in \c oldName and \c oldAddress. Then we clear these input + fields and turn off the read-only mode. The focus is set on \c nameLine + and we display \c submitButton and \c cancelButton. + + \snippet tutorials/addressbook/part2/addressbook.cpp addContact + + The \c submitContact() function can be divided into three parts: + + \list 1 + \li We extract the contact's details from \c nameLine and \c addressText + and store them in QString objects. We also validate to make sure that the + user did not click \uicontrol Submit with empty input fields; otherwise, a + QMessageBox is displayed to remind the user for a name and address. + + \snippet tutorials/addressbook/part2/addressbook.cpp submitContact part1 + + \li We then proceed to check if the contact already exists. If it does not + exist, we add the contact to \c contacts and we display a QMessageBox to + inform the user that the contact has been added. + + \snippet tutorials/addressbook/part2/addressbook.cpp submitContact part2 + + If the contact already exists, again, we display a QMessageBox to inform + the user about this, preventing the user from adding duplicate contacts. + Our \c contacts object is based on key-value pairs of name and address, + hence, we want to ensure that \e key is unique. + + \li Once we have handled both cases mentioned above, we restore the push + buttons to their normal state with the following code: + + \snippet tutorials/addressbook/part2/addressbook.cpp submitContact part3 + + \endlist + + The screenshot below shows the QMessageBox object we use to display + information messages to the user. + + \image addressbook-tutorial-part2-add-successful.png + + The \c cancel() function restores the last displayed contact details and + enables \c addButton, as well as hides \c submitButton and + \c cancelButton. + + \snippet tutorials/addressbook/part2/addressbook.cpp cancel + + The general idea behind adding a contact is to give the user the + flexibility to click \uicontrol Submit or \uicontrol Cancel at any time. The flowchart below + further explains this concept: + + \image addressbook-tutorial-part2-add-flowchart.png +*/ + +/*! + \example tutorials/addressbook/part3 + \title Part 3 - Navigating between Entries + \brief Explains the code that enables navigating the contacts. + + The address book is now about half complete. We should add the + capability to navigate the contacts, but first we must + decide what sort of a data structure we need for containing these + contacts. + + In the previous section, we used a QMap of key-value pairs with + the contact's name as the \e key, and the contact's address as the + \e value. This works well for our case. However, in order to + navigate and display each entry, a little bit of enhancement is + needed. + + We enhance the QMap by making it replicate a data structure similar to a + circularly-linked list, where all elements are connected, including the + first element and the last element. The figure below illustrates this data + structure. + + \image addressbook-tutorial-part3-linkedlist.png + + \section1 Defining the AddressBook Class + + To add navigation functions to the address book, we must add two + more slots to the \c AddressBook class: \c next() and \c + previous() to the \c addressbook.h file: + + \snippet tutorials/addressbook/part3/addressbook.h navigation functions + + We also require another two QPushButton objects, so we declare \c nextButton + and \c previousButton as private variables: + + \snippet tutorials/addressbook/part3/addressbook.h navigation pushbuttons + + \section1 Implementing the AddressBook Class + + In the \c AddressBook constructor in \c addressbook.cpp, we instantiate + \c nextButton and \c previousButton and disable them by default. This is + because navigation is only enabled when there is more than one contact + in the address book. + + \snippet tutorials/addressbook/part3/addressbook.cpp navigation pushbuttons + + We then connect these push buttons to their respective slots: + + \snippet tutorials/addressbook/part3/addressbook.cpp connecting navigation signals + + The image below is the expected graphical user interface. + + \image addressbook-tutorial-part3-screenshot.png + + We follow basic conventions for \c next() and \c previous() functions by + placing the \c nextButton on the right and the \c previousButton on the + left. In order to achieve this intuitive layout, we use QHBoxLayout to + place the widgets side-by-side: + + \snippet tutorials/addressbook/part3/addressbook.cpp navigation layout + + The QHBoxLayout object, \c buttonLayout2, is then added to \c mainLayout. + + \snippet tutorials/addressbook/part3/addressbook.cpp adding navigation layout + + The figure below shows the coordinates of the widgets in \c mainLayout. + \image addressbook-tutorial-part3-labeled-layout.png + + Within our \c addContact() function, we have to disable these buttons so + that the user does not attempt to navigate while adding a contact. + + \snippet tutorials/addressbook/part3/addressbook.cpp disabling navigation + + Also, in our \c submitContact() function, we enable the navigation + buttons, \c nextButton and \c previousButton, depending on the size + of \c contacts. As mentioned earlier, navigation is only enabled when + there is more than one contact in the address book. The following lines + of code demonstrates how to do this: + + \snippet tutorials/addressbook/part3/addressbook.cpp enabling navigation + + We also include these lines of code in the \c cancel() function. + + Recall that we intend to emulate a circularly-linked list with our QMap + object, \c contacts. So, in the \c next() function, we obtain an iterator + for \c contacts and then: + + \list + \li If the iterator is not at the end of \c contacts, we increment it + by one. + \li If the iterator is at the end of \c contacts, we move it to the + beginning of \c contacts. This gives us the illusion that our QMap is + working like a circularly-linked list. + \endlist + + \snippet tutorials/addressbook/part3/addressbook.cpp next() function + + Once we have iterated to the correct object in \c contacts, we display + its contents on \c nameLine and \c addressText. + + Similarly, for the \c previous() function, we obtain an iterator for + \c contacts and then: + + \list + \li If the iterator is at the end of \c contacts, we clear the + display and return. + \li If the iterator is at the beginning of \c contacts, we move it to + the end. + \li We then decrement the iterator by one. + \endlist + + \snippet tutorials/addressbook/part3/addressbook.cpp previous() function + + Again, we display the contents of the current object in \c contacts. + +*/ + +/*! + \example tutorials/addressbook/part4 + \title Part 4 - Editing and Removing Addresses + \brief Explains how to add edit and remove functionality. + + Now we look at ways to modify the contents of contacts stored in + the address book. + + \image addressbook-tutorial-screenshot.png + + We now have an address book that not only holds contacts in an + organized manner, but also allows navigation. It would be + convenient to include edit and remove functions so that a + contact's details can be changed when needed. However, this + requires a little improvement, in the form of enums. We defined + two modes: \c{AddingMode} and \c{NavigationMode}, but they were + not defined as enum values. Instead, we enabled and disabled the + corresponding buttons manually, resulting in multiple lines of + repeated code. + + Here we define the \c Mode enum with three different values: + + \list + \li \c{NavigationMode}, + \li \c{AddingMode}, and + \li \c{EditingMode}. + \endlist + + \section1 Defining the AddressBook Class + + The \c addressbook.h file is updated to contain the \c Mode enum: + + \snippet tutorials/addressbook/part4/addressbook.h Mode enum + + We also add two new slots, \c editContact() and \c removeContact(), to + our current list of public slots. + + \snippet tutorials/addressbook/part4/addressbook.h edit and remove slots + + In order to switch between modes, we introduce the \c updateInterface() function + to control the enabling and disabling of all QPushButton objects. We also + add two new push buttons, \c editButton and \c removeButton, for the edit + and remove functions mentioned earlier. + + \snippet tutorials/addressbook/part4/addressbook.h updateInterface() declaration + \dots + \snippet tutorials/addressbook/part4/addressbook.h buttons declaration + \dots + \snippet tutorials/addressbook/part4/addressbook.h mode declaration + + Lastly, we declare \c currentMode to keep track of the enum's current mode. + + \section1 Implementing the AddressBook Class + + We now implement the mode-changing features of the address + book. The \c editButton and \c removeButton are instantiated and + disabled by default. The address book starts with zero contacts + in memory. + + \snippet tutorials/addressbook/part4/addressbook.cpp edit and remove buttons + + These buttons are then connected to their respective slots, \c editContact() + and \c removeContact(), and we add them to \c buttonLayout1. + + \snippet tutorials/addressbook/part4/addressbook.cpp connecting edit and remove + \dots + \snippet tutorials/addressbook/part4/addressbook.cpp adding edit and remove to the layout + + The \c editContact() function stores the contact's old details in + \c oldName and \c oldAddress, before switching the mode to \c EditingMode. + In this mode, the \c submitButton and \c cancelButton are both enabled, + hence, the user can change the contact's details and click either button. + + \snippet tutorials/addressbook/part4/addressbook.cpp editContact() function + + The \c submitContact() function has been divided in two with an \c{if-else} + statement. We check \c currentMode to see if it's in \c AddingMode. If it is, + we proceed with our adding process. + + \snippet tutorials/addressbook/part4/addressbook.cpp submitContact() function beginning + \dots + \snippet tutorials/addressbook/part4/addressbook.cpp submitContact() function part1 + + Otherwise, we check to see if \c currentMode is in \c EditingMode. If it + is, we compare \c oldName with \c name. If the name has changed, we remove + the old contact from \c contacts and insert the newly updated contact. + + \snippet tutorials/addressbook/part4/addressbook.cpp submitContact() function part2 + + If only the address has changed (i.e., \c oldAddress is not the same as \c address), + we update the contact's address. Lastly, we set \c currentMode to + \c NavigationMode. This is an important step as it re-enables all the + disabled push buttons. + + To remove a contact from the address book, we implement the + \c removeContact() function. This function checks to see if the contact + exists in \c contacts. + + \snippet tutorials/addressbook/part4/addressbook.cpp removeContact() function + + If it does, we display a QMessageBox, to confirm the removal with the + user. Once the user has confirmed, we call \c previous() to ensure that the + user interface shows another contact, and we remove the contact using \l{QMap}'s + \l{QMap::remove()}{remove()} function. As a courtesy, we display a QMessageBox + to inform the user. Both the message boxes used in this function are shown below: + + \image addressbook-tutorial-part4-remove.png + + \section2 Updating the User Interface + + We mentioned the \c updateInterface() function earlier as a means to + enable and disable the push buttons depending on the current mode. + The function updates the current mode according to the \c mode argument + passed to it, assigning it to \c currentMode before checking its value. + + Each of the push buttons is then enabled or disabled, depending on the + current mode. The code for \c AddingMode and \c EditingMode is shown below: + + \snippet tutorials/addressbook/part4/addressbook.cpp update interface() part 1 + + For \c NavigationMode, however, we include conditions within the parameters + of the QPushButton::setEnabled() function. This is to ensure that + \c editButton and \c removeButton are enabled when there is at least one + contact in the address book; \c nextButton and \c previousButton are only + enabled when there is more than one contact in the address book. + + \snippet tutorials/addressbook/part4/addressbook.cpp update interface() part 2 + + By setting the mode and updating the user interface in the same + function, we avoid the possibility of the user interface getting + out of sync with the internal state of the application. + */ + +/*! + \example tutorials/addressbook/part5 + \title Part 5 - Adding a Find Function + \brief Describes how to add a find function. + + Here we look at ways to locate contacts and addresses in the + address book. + + \image addressbook-tutorial-part5-screenshot.png + + As we add contacts to our address book, it becomes tedious to + navigate the list with the \e Next and \e Previous buttons. A \e + Find function would be more efficient. The screenshot above shows + the \e Find button and its position on the panel of buttons. + + When the user clicks on the \e Find button, it is useful to + display a dialog that prompts for a contact's name. Qt provides + QDialog, which we subclass here to implement a \c FindDialog + class. + + \section1 Defining the FindDialog Class + + \image addressbook-tutorial-part5-finddialog.png + + In order to subclass QDialog, we first include the header for QDialog in + the \c finddialog.h file. Also, we use forward declaration to declare + QLineEdit and QPushButton since we will be using those widgets in our + dialog class. + + As in our \c AddressBook class, the \c FindDialog class includes + the Q_OBJECT macro and its constructor is defined to accept a parent + QWidget, even though the dialog will be opened as a separate window. + + \snippet tutorials/addressbook/part5/finddialog.h FindDialog header + + We define a public function, \c getFindText(), to be used by classes that + instantiate \c FindDialog. This function allows these classes to obtain the + search string entered by the user. A public slot, \c findClicked(), is also + defined to handle the search string when the user clicks the \uicontrol Find + button. + + Lastly, we define the private variables, \c findButton, \c lineEdit + and \c findText, corresponding to the \uicontrol Find button, the line edit + into which the user types the search string, and an internal string + used to store the search string for later use. + + \section1 Implementing the FindDialog Class + + Within the constructor of \c FindDialog, we set up the private variables, + \c lineEdit, \c findButton and \c findText. We use a QHBoxLayout to + position the widgets. + + \snippet tutorials/addressbook/part5/finddialog.cpp constructor + + We set the layout and window title, as well as connect the signals to their + respective slots. Notice that \c{findButton}'s \l{QPushButton::clicked()} + {clicked()} signal is connected to \c findClicked() and + \l{QDialog::accept()}{accept()}. The \l{QDialog::accept()}{accept()} slot + provided by QDialog hides the dialog and sets the result code to + \l{QDialog::}{Accepted}. We use this function to help \c{AddressBook}'s + \c findContact() function know when the \c FindDialog object has been + closed. We will explain this logic in further detail when discussing the + \c findContact() function. + + \image addressbook-tutorial-part5-signals-and-slots.png + + In \c findClicked(), we validate \c lineEdit to ensure that the user + did not click the \uicontrol Find button without entering a contact's name.

Otherwise, + we display the QMessageBox shown below to indicate that their search + failed. + + \image addressbook-tutorial-part5-notfound.png +*/ + +/*! + \example tutorials/addressbook/part6 + \title Part 6 - Loading and Saving + \brief Describes how to add save and load functionality. + + This part covers the Qt file handling features we use to write + loading and saving routines for the address book. + + \image addressbook-tutorial-part6-screenshot.png + + Although browsing and searching the contact list are useful + features, our address book is not complete until we can save + existing contacts and load them again at a later time. + + Qt provides a number of classes for \l{Input/Output and Networking} + {input and output}, but we have chosen to use two which are simple to use + in combination: QFile and QDataStream. + + A QFile object represents a file on disk that can be read from and written + to. QFile is a subclass of the more general QIODevice class which + represents many different kinds of devices. + + A QDataStream object is used to serialize binary data so that it can be + stored in a QIODevice and retrieved again later. Reading from a QIODevice + and writing to it is as simple as opening the stream - with the respective + device as a parameter - and reading from or writing to it. + + + \section1 Defining the AddressBook Class + + We declare two public slots, \c saveToFile() and \c loadFromFile(), as well + as two QPushButton objects, \c loadButton and \c saveButton. + + \snippet tutorials/addressbook/part6/addressbook.h save and load functions declaration + \dots + \snippet tutorials/addressbook/part6/addressbook.h save and load buttons declaration + + \section1 Implementing the AddressBook Class + + In our constructor, we instantiate \c loadButton and \c saveButton. + Ideally, it would be more user-friendly to set the push buttons' labels + to "Load contacts from a file" and "Save contacts to a file". However, due + to the size of our other push buttons, we set the labels to \uicontrol{Load...} + and \uicontrol{Save...}. Fortunately, Qt provides a simple way to set tooltips with + \l{QWidget::setToolTip()}{setToolTip()} and we use it in the following way + for our push buttons: + + \snippet tutorials/addressbook/part6/addressbook.cpp tooltip 1 + \dots + \snippet tutorials/addressbook/part6/addressbook.cpp tooltip 2 + + Although it is not shown here, just like the other features we implemented, + we add the push buttons to the layout panel on the right, \c buttonLayout1, + and we connect the push buttons' \l{QPushButton::clicked()}{clicked()} + signals to their respective slots. + + For the saving feature, we first obtain \c fileName using + QFileDialog::getSaveFileName(). This is a convenience function provided + by QFileDialog, which pops up a modal file dialog and allows the user to + enter a file name or select any existing \c{.abk} file. The \c{.abk} file + is our Address Book extension that we create when we save contacts. + + \snippet tutorials/addressbook/part6/addressbook.cpp saveToFile() function part1 + + The file dialog that pops up is displayed in the screenshot below: + + \image addressbook-tutorial-part6-save.png + + If \c fileName is not empty, we create a QFile object, \c file, with + \c fileName. QFile works with QDataStream as QFile is a QIODevice. + + Next, we attempt to open the file in \l{QIODeviceBase::}{WriteOnly} mode. + If this is unsuccessful, we display a QMessageBox to inform the user. + + \snippet tutorials/addressbook/part6/addressbook.cpp saveToFile() function part2 + + Otherwise, we instantiate a QDataStream object, \c out, to write the open + file. QDataStream requires that the same version of the stream is used + for reading and writing. We ensure that this is the case by setting the + version used to the \l{QDataStream::Qt_4_5}{version introduced with Qt 4.5} + before serializing the data to \c file. + + \snippet tutorials/addressbook/part6/addressbook.cpp saveToFile() function part3 + + For the loading feature, we also obtain \c fileName using + QFileDialog::getOpenFileName(). This function, the counterpart to + QFileDialog::getSaveFileName(), also pops up the modal file dialog and + allows the user to enter a file name or select any existing \c{.abk} file + to load it into the address book. + + \snippet tutorials/addressbook/part6/addressbook.cpp loadFromFile() function part1 + + On Windows, for example, this function pops up a native file dialog, as + shown in the following screenshot. + + \image addressbook-tutorial-part6-load.png + + If \c fileName is not empty, again, we use a QFile object, \c file, and + attempt to open it in \l{QIODeviceBase::}{ReadOnly} mode. Similar to our + implementation of \c saveToFile(), if this attempt is unsuccessful, we + display a QMessageBox to inform the user. + + \snippet tutorials/addressbook/part6/addressbook.cpp loadFromFile() function part2 + + Otherwise, we instantiate a QDataStream object, \c in, set its version as + above and read the serialized data into the \c contacts data structure. + The \c contacts object is emptied before data is read into it to simplify + the file reading process. A more advanced method would be to read the + contacts into a temporary QMap object, and copy over non-duplicate contacts + into \c contacts. + + \snippet tutorials/addressbook/part6/addressbook.cpp loadFromFile() function part3 + + To display the contacts that have been read from the file, we must first + validate the data obtained to ensure that the file we read from actually + contains address book contacts. If it does, we display the first contact; + otherwise, we display a QMessageBox to inform the user about the problem. + Lastly, we update the interface to enable and disable the push buttons + accordingly. +*/ + +/*! + \example tutorials/addressbook/part7 + \title Part 7 - Additional Features + \brief Describes how to export data in VCard format. + + This part covers some additional features that make the address + book more convenient for the frequent user. + + \image addressbook-tutorial-part7-screenshot.png + + Although our address book is useful in isolation, it would be + better if we could exchange contact data with other applications. + The vCard format is a popular file format that can be used for + this purpose. Here we extend our address book client to allow + contacts to be exported to vCard \c{.vcf} files. + + \section1 Defining the AddressBook Class + + We add a QPushButton object, \c exportButton, and a corresponding public + slot, \c exportAsVCard() to our \c AddressBook class in the + \c addressbook.h file. + + \snippet tutorials/addressbook/part7/addressbook.h exportAsVCard() declaration + \dots + \snippet tutorials/addressbook/part7/addressbook.h exportButton declaration + + \section1 Implementing the AddressBook Class + + Within the \c AddressBook constructor, we connect \c{exportButton}'s + \l{QPushButton::clicked()}{clicked()} signal to \c exportAsVCard(). + We also add this button to our \c buttonLayout1, the layout responsible + for our panel of buttons on the right. + + In our \c exportAsVCard() function, we start by extracting the contact's + name into \c name. We declare \c firstName, \c lastName and \c nameList. + Next, we look for the index of the first white space in \c name. If there + is a white space, we split the contact's name into \c firstName and + \c lastName. Then, we replace the space with an underscore ("_"). + Alternately, if there is no white space, we assume that the contact only + has a first name. + + \snippet tutorials/addressbook/part7/addressbook.cpp export function part1 + + As with the \c saveToFile() function, we open a file dialog to let the user + choose a location for the file. Using the file name chosen, we create an + instance of QFile to write to. + + We attempt to open the file in \l{QIODeviceBase::}{WriteOnly} mode. If this + process fails, we display a QMessageBox to inform the user about the + problem and return. Otherwise, we pass the file as a parameter to a + QTextStream object, \c out. Like QDataStream, the QTextStream class + provides functionality to read and write plain text to files. As a result, + the \c{.vcf} file generated can be opened for editing in a text editor. + + \snippet tutorials/addressbook/part7/addressbook.cpp export function part2 + + We then write out a vCard file with the \c{BEGIN:VCARD} tag, followed by + the \c{VERSION:2.1} tag. The contact's name is written with the \c{N:} + tag. For the \c{FN:} tag, which fills in the "File as" property of a vCard, + we have to check whether the contact has a last name or not. If the contact + does, we use the details in \c nameList to fill it. Otherwise, we write + \c firstName only. + + \snippet tutorials/addressbook/part7/addressbook.cpp export function part3 + + We proceed to write the contact's address.
