It will also explain how to integrate an SQL database into a Qt -application. - -\section1 Chapter 1: Setting Up - -When setting up a new project, it's easiest to use -\l {Qt Creator Manual}{Qt Creator}. For this project, we chose the -\l {Qt Creator: Creating Qt Quick Projects}{Qt Quick application} template, which creates a -basic "Hello World" application with the following files: - -\list -\li \c MainForm.ui.qml - Defines the default UI -\li \c main.qml - Embeds the default UI in a Window -\li \c qml.qrc - Lists the \c .qml files that are built into the binary -\li \c main.cpp - Loads \c main.qml -\li \c chattutorial.pro - Provides the qmake configuration -\endlist - -\note Delete the \c MainForm.ui.qml from the project as we will -not use it in this tutorial. - -\section2 main.cpp - -The default code in \c main.cpp has two includes: - -\quotefromfile chattutorial/chapter1-settingup/main.cpp -\skipto include -\printline include -\printline include - -The first gives us access to QGuiApplication. All Qt applications require -an application object, but the precise type depends on what the application -does. QCoreApplication is sufficient for non-graphical applications. -QGuiApplication is sufficient for graphical applications that do not use -\l {Qt Widgets}, while QApplication is required for those that do. - -The second include makes QQmlApplicationEngine available, along with -some useful functions required for making C++ types accessible from QML. - -Within \c main(), we set up the application object and QML engine: - -\skipto main -\printuntil } - -It begins with enabling \l {High DPI}{high DPI scaling}, which is not -part of the default code. It is necessary to do so before the application -object is constructed. - -After that's done, we construct the application object, passing any application -arguments provided by the user. - -Next, the QML engine is created. \l QQmlApplicationEngine is a convenient -wrapper over QQmlEngine, providing the \l {QQmlApplicationEngine::load}{load()} -function to easily load QML for an application. It also adds some convenience -for using \l {Using File Selectors with Qt Quick Controls}{file selectors}. - -Once we've set up things in C++, we can move on to the user interface in QML. - -\section2 main.qml - -Let's modify the default QML code to suit our needs. - -\quotefromfile chattutorial/chapter1-settingup/main.qml -\skipto import -\printuntil import QtQuick.Controls - -First, import the \l {Qt Quick} module. This gives us -access to graphical primitives such as \l Item, \l Rectangle, \l Text, and so -on. -For the full list of types, see the \l {Qt Quick QML Types} documentation. - -Next, import the Qt Quick Controls module. Amongst other things, this -provides access to \l ApplicationWindow, which will replace the existing -root type, \c Window: - -\skipto ApplicationWindow -\printuntil visible: true -\dots -\skipto } -\skipuntil } -\printuntil } - -ApplicationWindow is a \l Window with some added convenience for creating a -\l {ApplicationWindow::}{header} and a \l {ApplicationWindow::}{footer}. -It also provides the foundation for \l {Popup}{popups} and supports some -basic styling, such as the background \l {Window::}{color}. - -There are three properties that are almost always set when using -ApplicationWindow: \l {Window::}{width}, \l {Window::}{height}, and -\l {Window::}{visible}. -Once we've set these, we have a properly sized, empty window ready to be -filled with content. - -\note The \c title property from the default code is removed. - -The first \e "screen" in our application will be a list of contacts. It would -be nice to have some text at the top of each screen that describes its purpose. -The header and footer properties of ApplicationWindow could work in -this situation. They have some characteristics that make them ideal for -items that should be displayed on every screen of an application: - -\list -\li They are anchored to the top and bottom of the window, respectively. -\li They fill the width of the window. -\endlist - -However, when the contents of the header and footer varies depending on -which screen the user is viewing, it is much easier to use \l Page. -For now, we'll just add one page, but in the next chapter, we'll demonstrate -how to navigate between several pages. - -\quotefromfile chattutorial/chapter1-settingup/main.qml -\skipto Page -\printuntil } -\printuntil } - -We replace the default \c{MainForm {...}} code block with a Page, which is -sized to occupy all the space on the window using the \l {Item::}{anchors.fill} -property. - -Then, we assign a \l Label to its \l {Page::}{header} property. Label extends -the primitive \l Text item from the Qt Quick module by adding -\l{Styling Qt Quick Controls}{styling} and \l {Control::}{font} inheritance. -This means that a Label can look different depending on which style is in use, -and can also propagate its pixel size to its children. - -We want some distance between the top of the application window and the text, -so we set the \l {Text::padding}{padding} property. This allocates extra -space on each side of the label (within its bounds). We can also explicitly set -the \l {Text::}{topPadding} and \l {Text::}{bottomPadding} properties instead. - -We set the text of the label using the \c qsTr() function, which ensures that -the text can be translated by \l {Writing Source Code for Translation}{Qt's -translation system}. It's a good practice to follow for text that is visible to -the end users of your application. - -By default, text is vertically aligned to the top of its bounds, while the -horizontal alignment depends on the natural direction of the text; for example, -text that is read from left to right will be aligned to the left. If we -used these defaults, our text would be at the top-left corner of the window. -This is not desirable for a header, so we align the text to the center of its -bounds, both horizontally and vertically. - -\section2 The Project File - -The \c .pro or \l {Creating Project Files}{project} file contains all of the -information needed by \l {qmake Manual}{qmake} to generate a Makefile, which is -then used to compile and link the application. - -\quotefromfile chattutorial/chapter1-settingup/chapter1-settingup.pro -\printline TEMPLATE - -The first line tells \c qmake which kind of project this is. We're building an -application, so we use the \c app template. - -\printline QT - -The next line declares the Qt libraries that we want to use from C++. - -\printline CONFIG - -This line states that a C++11 compatible compiler is required to build the -project. - -\printline SOURCES - -The \c SOURCES variable lists all of the source files that should be compiled. -A similar variable, \c HEADERS, is available for header files. - -\printline RESOURCES - -The next line tells \c qmake that we have a collection of -\l {The Qt Resource System}{resources} that should be built into the -executable. - -\printline target.path - -This line replaces deployment settings that come with the default project file. -It determines where the example is copied, on running "\c{make install}". - -Now we can build and run the application: - -\borderedimage qtquickcontrols2-chattutorial-chapter1.png - -\noautolist -\generatelist examplefiles .*chapter1.* - -\section1 Chapter 2: Lists - -In this chapter, we'll explain how to create a list of interactive items using -\l ListView and \l ItemDelegate. - -ListView comes from the Qt Quick module, and displays a list of items -populated from a \l {Models and Views in Qt Quick}{model}. ItemDelegate comes from -the Qt Quick Controls module, and provides a standard view item for use in views -and controls such as ListView and \l ComboBox. For example, each ItemDelegate -can display text, be checked on and off, and react to mouse clicks. - -Here is our ListView: - -\quotefromfile chattutorial/chapter2-lists/main.qml -\dots 8 -\codeline -\skipto ListView -\printuntil } -\printuntil } -\printuntil } -\codeline -\dots 8 - -\section2 Sizing and Positioning - -The first thing we do is set a size for the view. It should fill the available -space on the page, so we use \l {Item::}{anchors.fill}. Note that -Page ensures that its header and footer have enough of their own space -reserved, so the view in this case will sit below the header, for example. - -Next, we set \l {Flickable::leftMargin}{margins} around the ListView to put -some distance between it and the edges of the window. The margin properties -reserve space within the bounds of the view, which means that the empty areas -can still be \e "flicked" by the user. - -The items should be nicely spaced out within the view, so the -\l {ListView::}{spacing} property is set to \c 20. - -\section2 Model - -In order to quickly populate the view with some items, we've used a JavaScript -array as the model. One of the greatest strengths of QML is its ability to -make prototyping an application extremely quick, and this is an example of -that. It's also possible to simply assign a \l {Integers as Models}{number} to -the model property to indicate how many items you need. For example, if you -assign \c 10 to the \c model property, each item's display text will be a -number from \c 0 to \c 9. - -However, once the application gets past the prototype stage, it quickly becomes -necessary to use some real data. For this, it's best to use a proper C++ model -by \l {QAbstractItemModel}{subclassing QAbstractItemModel}. - -\section2 Delegate - -On to the \l {ListView::}{delegate}. We assign the corresponding text from the -model to the \l {AbstractButton::text}{text} property of ItemDelegate. The exact -manner in which the data from the model is made available to each delegate -depends on the type of model used. See \l {Models and Views in Qt Quick} for -more information. - -In our application, the width of each item in the view should be the same -as the width of the view. This ensures that the user has a lot of room with -which to select a contact from the list, which is an important factor on -devices with small touch screens, like mobile phones. However, the width of the -view includes our \c 48 pixel margins, so we must account for that in our -assignment to the width property. - -Next, we define an \l Image. This will display a picture of the user's contact. -The image will be \c 40 pixels wide and \c 40 pixels high. We'll base the -height of the delegate on the image's height, so that we don't have any empty -vertical space. - -\borderedimage qtquickcontrols2-chattutorial-chapter2.png - -\generatelist examplefiles .*(chapter2|shared).* -\generatelist exampleimages .*shared.*(Einstein|Hemingway|Gude)\.png - -\section1 Chapter 3: Navigation - -In this chapter, you'll learn how to use \l StackView to navigate between pages -in an application. Here's the revised \c main.qml: - -\quotefromfile chattutorial/chapter3-navigation/main.qml -\skipto import -\printuntil } -\printuntil } -\printuntil } - -\section2 Navigating with StackView - -As its name suggests, StackView provides stack-based navigation. The last item -to be \e "pushed" onto the stack is the first one to be removed, and the -top-most item is always the one that is visible. - -In the same manner as we did with Page, we tell the StackView to fill the -application window. The only thing left to do after that is to give it an item -to display, via \l {StackView::}{initialItem}. StackView accepts -\l {Item}{items}, \l {Component}{components} and \l [QML]{url}{URLs}. - -You'll notice that we moved the code for the contact list into -\c ContactPage.qml. It's a good idea to do this as soon as you have a general -idea of which screens your application will contain. Doing so not only makes -your code easier to read, but ensures that items are only instantiated from -a given component when completely necessary, reducing memory usage. - -\note Qt Creator provides several convenient \l {http://doc.qt.io/qtcreator/creator-editor-refactoring.html#refactoring-qml-code}{refactoring options for QML}, -one of which allows you to move a block of code into a separate file - (\c {Alt + Enter > Move Component into Separate File}). - -Another thing to consider when using ListView is whether to refer to it by -\c id, or use the attached \l {ListView::view}{ListView.view} -property. The best approach depends on a few different factors. Giving the -view an id will result in shorter and more efficient binding expressions, as -the attached property has a very small amount of overhead. However, if you plan -on reusing the delegate in other views, it is better to use the attached -properties to avoid tying the delegate to a particular view. For example, using -the attached properties, the \c width assignment in our delegate becomes: - -\code -width: ListView.view.width - ListView.view.leftMargin - ListView.view.rightMargin -\endcode - -In chapter 2, we added a ListView below the header. If you run the application -for that chapter, you'll see that the contents of the view can be scrolled over -the top of the header: - -\borderedimage qtquickcontrols2-chattutorial-chapter2-listview-header.gif - -This is not that nice, especially if the text in the -delegates is long enough that it reaches the text in the header. What we -ideally want to do is to have a solid block of color under the header text, but -\e {above} the view. This ensures that the listview contents can't visually -interfere with the header contents. Note that it's also possible to achieve -this by setting the \l {Item::}{clip} property of the view to \c true, but -doing so \l {Clipping}{can affect performance}. - -\l ToolBar is the right tool for this job. It is a container of both -application-wide and context-sensitive actions and controls, such as navigation -buttons and search fields. Best of all, it has a background color that, as -usual, comes from the application style. Here it is in action: - -\quotefromfile chattutorial/chapter3-navigation/ContactPage.qml -\skipto header -\printuntil } -\printuntil } - -\borderedimage qtquickcontrols2-chattutorial-chapter3-listview-header.gif - -It has no layout of its own, so we center the label within it ourselves. - -The rest of the code is the same as it was in chapter 2, except that we've -taken advantage of the \l {AbstractButton::}{clicked} signal to push the next -page onto the stackview: - -\skipto onClicked -\printline onClicked - -When pushing a \l Component or \l [QML] url onto StackView, it's often -necessary to initialize the (eventually) instantiated item with some variables. -StackView's \l {StackView::push}{push()} function accounts for this, by taking a JavaScript object -as the second argument. We use this to provide the next page with a contact's -name, which it then uses to display the relevant conversation. Note the -\c {root.StackView.view.push} syntax; this is necessary because of how -\l {A Note About Accessing Attached Properties and Signal Handlers} -{attached properties} work. - -Let's step through \c ConversationPage.qml, beginning with the imports: - -\quotefromfile chattutorial/chapter3-navigation/ConversationPage.qml -\skipto import -\printline import -\printline import -\printline import - -These are the same as before, except for the addition of the \c QtQuick.Layouts -import, which we'll cover shortly. - -\skipto Page -\printuntil } -\printuntil } -\printuntil } -\dots 4 - -The root item of this component is another Page, which has a custom property -called \c inConversationWith. For now, this property will simply determine what -the label in the header displays. Later on, we'll use it in the SQL query that -populates the list of messages in the conversation. - -To allow the user to go back to the Contact page, we add a \l ToolButton that -calls \l {StackView::pop}{pop()} when clicked. A \l ToolButton is functionally -similar to \l Button, but provides a look that is more suitable within a -ToolBar. - -There are two ways of laying out items in QML: \l {Item Positioners} -and \l {Qt Quick Layouts}. Item positioners (\l Row, \l Column, and so on) are -useful for situations where the size of items is known or fixed, and all that -is required is to neatly position them in a certain formation. The layouts in -Qt Quick Layouts can both position and resize items, making them well suited -for resizable user interfaces. Below, we use \l ColumnLayout to vertically -lay out a ListView and a \l Pane: - -\skipto ColumnLayout -\printto Layout.margins -\codeline -\dots 12 -\codeline -\skipuntil ScrollBar -\printline } -\codeline -\dots 8 -\codeline -\printuntil Layout.fillWidth: true -\dots 12 -\skipuntil } -\skipuntil } -\skipuntil } -\skipuntil } -\printline } - -Pane is basically a rectangle whose color comes from the application's style. -It is similar to \l Frame, with the only difference being that it has no stroke -around its border. - -Items that are direct children of a layout have various -\l {Layout}{attached properties} available to them. We use -\l {Layout::fillWidth}{Layout.fillWidth} and -\l {Layout::fillHeight}{Layout.fillHeight} on the ListView to ensure -that it takes as much space within the ColumnLayout as it can. The -same is done for the Pane. As ColumnLayout is a vertical layout, there -aren't any items to the left or right of each child, so this will result in -each item consuming the entire width of the layout. - -On the other hand, the \l {Layout::fillHeight}{Layout.fillHeight} statement in -the ListView will enable it to occupy the remaining space that is left after -accommodating the Pane. - -Let's look at the listview in detail: - -\quotefromfile chattutorial/chapter3-navigation/ConversationPage.qml -\skipto ListView -\printuntil ScrollBar -\printuntil } - -After filling the width and height of its parent, we also set some margins on -the view. This gives us a nice alignment with the placeholder text in the -"compose message" field: - -\borderedimage qtquickcontrols2-chattutorial-chapter3-view-margins.png - -Next, we set \l {ListView::}{displayMarginBeginning} and \l -{ListView::}{displayMarginEnd}. These properties ensure that the delegates -outside the bounds of the view do not disappear while scrolling at the edges of -the view. It's easiest to understand this by commenting out the properties and -seeing what happens when scrolling the view. - -We then flip the vertical direction of the view, so that first items are at the -bottom. The delegates are spaced out by 12 pixels, and a \e "dummy" model is -assigned for testing purposes, until we implement the real model in chapter 4. - -Within the delegate, we declare a \l Row as the root item, as we want the -avatar to be followed by the message contents, as shown in the image above. - -Messages sent by the user should be distinguished from those sent by a contact. -For now, we set a dummy property \c sentByMe, which simply uses the index -of the delegate to alternate between different authors. Using this property, -we distinguish between different authors in three ways: - -\list -\li Messages sent by the user are aligned to the right side of the screen -by setting \c anchors.right to \c listView.contentItem.right. - -\li By setting the \c visible property of the avatar (which is simply a -Rectangle for now) based on \c sentByMe, we only show it if the message was -sent by a contact. - -\li We change the color of the rectangle depending on the author. Since we -do not want to display dark text on a dark background, and vice versa, we also -set the text color depending on who the author is. In chapter 5, we'll see how -styling takes care of matters like this for us. -\endlist - -At the bottom of the screen, we place a \l TextArea item to allow multi-line -text input, and a button to send the message. We use Pane to cover the area -under these two items, in the same way that we use ToolBar to prevent the -contents of the listview from interfering with the page header: - -\skipto Pane -\printuntil } -\printuntil } -\printuntil } -\printuntil } - -The TextArea should fill the available width of the screen. We assign some -placeholder text to provide a visual cue to the user as to where they should -begin typing. The text within the input area is wrapped to ensure that it -does not go outside of the screen. - -Finally, the button is only enabled when there is actually a message to send. - -\borderedimage qtquickcontrols2-chattutorial-chapter3.gif - -\generatelist examplefiles .*(chapter3|shared).* -\generatelist exampleimages .*shared.*(Einstein|Hemingway|Gude)\.png - -\section1 Chapter 4: Models - -In chapter 4, we'll take you through the process of creating both read-only and -read-write SQL models in C++ and exposing them to QML to populate views. - -\section2 QSqlQueryModel - -In order to keep the tutorial simple, we've chosen to make the list of user -contacts non-editable. \l QSqlQueryModel is the logical choice for this -purpose, as it provides a read-only data model for SQL result sets. - -Let's take a look at our \c SqlContactModel class that derives from -QSqlQueryModel: - -\quotefromfile chattutorial/chapter4-models/sqlcontactmodel.h -\skipto #include -\printuntil }; - -There's not much going on here, so let's move on to the \c .cpp file: - -\quotefromfile chattutorial/chapter4-models/sqlcontactmodel.cpp -\skipto #include -\printuntil } -\printuntil } -\printuntil } - -We include the header file of our class and those that we require from Qt. We -then define a static function named \c createTable() that we'll use to create -the SQL table (if it doesn't already exist), and then populate it with some -dummy contacts. - -The call to \l {QSqlDatabase::database}{database()} might look a little bit -confusing because we have not set up a specific database yet. If no connection -name is passed to this function, it will return a \e {"default connection"}, -whose creation we will cover soon. - -\skipto SqlContactModel -\printuntil } - -In the constructor, we call \c createTable(). We then construct a query that -will be used to populate the model. In this case, we are simply interested in -all rows of the \c Contacts table. - -\section2 QSqlTableModel - -\c SqlConversationModel is more complex: - -\quotefromfile chattutorial/chapter4-models/sqlconversationmodel.h -\skipto #include -\printuntil }; - -We use both the \c Q_PROPERTY and \c Q_INVOKABLE macros, and therefore we must -let \l {Using the Meta-Object Compiler (moc)}{moc} know by using the \c -Q_OBJECT macro. - -The \c recipient property will be set from QML to let the model know which -conversation it should retrieve messages for. - -We override the \l {QSqlTableModel::data}{data()} and -\l {QAbstractItemModel::}{roleNames()} functions so that we can use our -custom roles in QML. - -We also define the \c sendMessage() function that we want to call from -QML, hence the \c Q_INVOKABLE macro. - -Let's take a look at the \c .cpp file: - -\quotefromfile chattutorial/chapter4-models/sqlconversationmodel.cpp -\skipto #include -\printuntil } -\printuntil } -\printuntil } - -This is very similar to \c sqlcontactmodel.cpp, with the exception that we are -now operating on the \c Conversations table. We also define -\c conversationsTableName as a static const variable, as we use it in a couple -of places throughout the file. - -\skipto SqlConversationModel -\printuntil } - -As with \c SqlContactModel, the first thing that we do in the constructor is -create the table. We tell QSqlTableModel the name of the table we'll be using -via the \l {QSqlTableModel::setTable}{setTable()} function. To ensure that the -latest messages in the conversation are shown first, we sort the query results -by the \c timestamp field in descending order. This goes hand in hand with -setting ListView's \l {ListView::}{verticalLayoutDirection} property to -\c ListView.BottomToTop (which we covered in chapter 3). - -\skipto ::recipient( -\printuntil } -\printuntil } - -In \c setRecipient(), we set a filter over the results returned from -the database. - -\skipto ::data( -\printuntil } - -The \c data() function falls back to QSqlTableModel's implementation if the -role is not a custom user role. If the role is a user role, we can subtract -Qt::UserRole from it to get the index of that field and then use that to find -the value that we need to return. - -\skipto ::roleNames( -\printuntil } - -In \c roleNames(), we return a mapping of our custom role values to role names. -This enables us to use these roles in QML. It can be useful to declare an enum -to hold all of the role values, but since we don't refer to any specific value -in code outside of this function, we don't bother. - -\skipto ::sendMessage( -\printuntil } - -The \c sendMessage() function uses the given \c recipient and a \c message to -insert a new record into the database. Due to our usage -of \l QSqlTableModel::OnManualSubmit, we must manually call -\l {QSqlTableModel::submitAll}{submitAll()}. - -\section2 Connecting to the Database and Registering Types With QML - -Now that we've established the model classes, let's take a look at \c main.cpp: - -\quotefromfile chattutorial/chapter4-models/main.cpp -\skipto #include -\printuntil return app.exec(); -\printuntil } - -\c connectToDatabase() creates the connection to the SQLite database, creating -the actual file if it doesn't already exist. - -Within \c main(), we call \l {qmlRegisterType}{qmlRegisterType()} to -register our models as types within QML. - -\section2 Using the Models in QML - -Now that we have the models available as QML types, there are some minor -changes to be done to \c ContactPage.qml. To be able to use the types, -we must first import them using the URI we set in \c main.cpp: - -\quotefromfile chattutorial/chapter4-models/ContactPage.qml -\skipto import io.qt.examples.chattutorial -\printline import io.qt.examples.chattutorial - -We then replace the dummy model with the proper one: - -\skipto model: SqlContactModel {} -\printline model: SqlContactModel {} - -Within the delegate, we use a different syntax for accessing the model data: - -\skipto text: model.display -\printline text: model.display - -In \c ConversationPage.qml, we add the same \c chattutorial import, and replace -the dummy model: - -\quotefromfile chattutorial/chapter4-models/ConversationPage.qml -\skipto model: SqlConversationModel { -\printuntil } - -Within the model, we set the \c recipient property to the name of the contact -for which the page is being displayed. - -The root delegate item changes from a Row to a Column, to accommodate the -timestamp that we want to display below every message: - -\skipto delegate: Column { -\printuntil Label { -\printuntil } -\printuntil } -\printuntil } -\printuntil } -\printuntil } - -\borderedimage qtquickcontrols2-chattutorial-chapter4-message-timestamp.png - -Now that we have a proper model, we can use its \c recipient role in the -expression for the \c sentByMe property. - -The Rectangle that was used for the avatar has been converted into an Image. -The image has its own implicit size, so we don't need to specify it explicitly. -As before, we only show the avatar when the author isn't the user, except this -time we set the \c source of the image to an empty URL instead of using the -\c visible property. - -We want each message background to be slightly wider (12 pixels each side) than -its text. However, if it's too long, we want to limit its width to the edge -of the listview, hence the usage of \c Math.min(). When the message wasn't sent -by us, an avatar will always come before it, so we account for that by -subtracting the width of the avatar and the row spacing. - -For example, in the image above, the implicit width of the message text is the -smaller value. However, in the image below, the message text is quite long, so -the smaller value (the width of the view) is chosen, ensuring that the text -stops at the opposite edge of the screen: - -\borderedimage qtquickcontrols2-chattutorial-chapter4-long-message.png - -In order to display the timestamp for each message that we discussed earlier, -we use a Label. The date and time are formatted with -\l {QtQml::Qt::formatDateTime}{Qt.formatDateTime()}, using a custom format. - -The \e "send" button must now react to being clicked: - -\skipto Button -\printuntil } -\printuntil } - -First, we call the invokable \c sendMessage() function of the model, which -inserts a new row into the Conversations database table. Then, we clear the -text field to make way for future input. - -\borderedimage qtquickcontrols2-chattutorial-chapter4.gif - -\generatelist examplefiles .*(chapter4|shared).* -\generatelist exampleimages - -\section1 Chapter 5: Styling - -Styles in Qt Quick Controls are designed to work on any platform. In this -chapter, we'll do some minor visual tweaks to make sure our application -looks good when run with the \l {Basic Style}{Basic}, -\l {Material Style}{Material}, and \l {Universal Style}{Universal} styles. - -So far, we've just been testing the application with the Basic style. If we -run it with the \l {Material Style}, for example, we'll immediately see some issues. -Here is the Contacts page: - -\borderedimage qtquickcontrols2-chattutorial-chapter5-contacts-material-test.png - -The header text is black on a dark blue background, which is very difficult to -read. The same thing occurs with the Conversations page: - -\borderedimage qtquickcontrols2-chattutorial-chapter5-conversations-material-test.png - -The solution is to tell the toolbar that it should use the \e "Dark" theme, so -that this information is propagated to its children, allowing them to switch -their text color to something lighter. The simplest way of doing so is to -import the Material style directly and use the Material attached property: - -\code - import QtQuick.Controls.Material 2.12 - - // ... - - header: ToolBar { - Material.theme: Material.Dark - - // ... - } -\endcode - -However, this brings with it a hard dependency to the Material style; the -Material style plugin \e must be deployed with the application, even if the -target device doesn't use it, otherwise the QML engine will fail to find the -import. - -Instead, it is better to rely on Qt Quick Controls's built-in support for -\l {Using File Selectors with Qt Quick Controls}{style-based file selectors}. -To do this, we must move the ToolBar out into its own file. We'll call it -\c ChatToolBar.qml. This will be the \e "default" version of the file, which -means that it will be used when the \l {Basic Style}{Basic style} (which is the -style that is used when none is specified) is in -use. Here's the new file: - -\quotefromfile chattutorial/chapter5-styling/ChatToolBar.qml -\skipto import -\printuntil } - -As we only use the ToolBar type within this file, we only need the -Qt Quick Controls import. The code itself has not changed from how it was -in \c ContactPage.qml, which is how it should be; for the default version -of the file, nothing needs to be different. - -Back in \c ContactPage.qml, we update the code to use the new type: - -\quotefromfile chattutorial/chapter5-styling/ContactPage.qml -\skipto ToolBar -\printuntil } -\printuntil } - -Now we need to add the Material version of the toolbar. File selectors expect -variants of a file to be in appropriately named directories that exist -alongside the default version of the file. This means that we need to add a -folder named "+Material" in the same directory that ChatToolBar.qml is in: -the root folder. The "+" is required by \l QFileSelector as a way of ensuring -that the selection feature is not accidentally triggered. - -Here's \c +Material/ChatToolBar.qml: - -\quotefromfile chattutorial/chapter5-styling/+Material/ChatToolBar.qml -\skipto import -\printuntil } - -We'll make the same changes to \c ConversationPage.qml: - -\quotefromfile chattutorial/chapter5-styling/ConversationPage.qml -\skipto header: ChatToolBar -\printuntil } -\printuntil } -\printuntil } - -Now both pages look correct: - -\borderedimage qtquickcontrols2-chattutorial-chapter5-contacts-material.png -\borderedimage qtquickcontrols2-chattutorial-chapter5-conversations-material.png - -Let's try out the Universal style: - -\borderedimage qtquickcontrols2-chattutorial-chapter5-contacts-universal.png -\borderedimage qtquickcontrols2-chattutorial-chapter5-conversations-universal.png - -No issues there. For a relatively simple application such as this one, there -should be very few adjustments necessary when switching styles. - -Now let's try each style's dark theme. The Basic style has no dark theme, as -it would add a slight overhead to a style that is designed to be as performant -as possible. We'll test out the Material style first, so add an entry to -\c qtquickcontrols2.conf that tells it to use its dark theme: - -\code -[Material] -Primary=Indigo -Accent=Indigo -Theme=Dark -\endcode - -Once this is done, build and run the application. This is what you should see: - -\borderedimage qtquickcontrols2-chattutorial-chapter5-contacts-material-dark.png -\borderedimage qtquickcontrols2-chattutorial-chapter5-conversations-material-dark.png - -Both pages look fine. Now add an entry for the Universal style: - -\code -[universal] -Theme=Dark -\endcode - -After building and running the application, you should see these results: - -\borderedimage qtquickcontrols2-chattutorial-chapter5-contacts-universal-dark.png -\borderedimage qtquickcontrols2-chattutorial-chapter5-conversations-universal-dark.png - -\generatelist examplefiles .*(chapter5|shared).* -\generatelist exampleimages - -\section1 Summary - -In this tutorial, we've taken you through the following steps of writing a -basic application using Qt Quick Controls: - -\list -\li Creating a new project using Qt Creator. -\li Setting up a basic ApplicationWindow. -\li Defining headers and footers with Page. -\li Displaying content in a ListView. -\li Refactoring components into their own files. -\li Navigating between screens with StackView. -\li Using layouts to allow an application to resize gracefully. -\li Implementing both custom read-only and writable models that integrate an -SQL database into the application. -\li Integrating C++ with QML via \l Q_PROPERTY, \l Q_INVOKABLE, and -\l qmlRegisterType(). -\li Testing and configuring multiple styles. -\endlist -
