Move findfiles example into manual tests
The example follows bad and outdated practices: - running time consuming and I/O heavy workload in the GUI thread - calling processEvents to keep the UI responsive - showing results only at the end of a search rather than continuously Perhaps this example can be rewritten at some point to apply modern practices (at least use a thread and emit signals), but it seems to have low overall educational value. Moving it to be a manual test for now.

- \example dialogs/findfiles
- \title Find Files Example
- \ingroup examples-dialogs
-
- \brief A dialog for finding files in a specified folder.
-
- The Find Files application allows the user to search for files in a
- specified directory, matching a given file name or wildcard,
- and containing a specified string (if filled in). The search
- result is displayed in a table containing the names of the files
- and their sizes. The application also shows the number of files found.
-
- The Find Files example illustrates the use of several classes:
-
- \table
- \row
- \li QProgressDialog
- \li Provide feedback on the progress of a search operation
- \row
- \li QFileDialog
- \li Browse through a file list
- \row
- \li QTextStream
- \li Use stream operators to read a file
- \row
- \li QTableWidget
- \li Browse through the search results in a table
- \row
- \li QDesktopServices
- \li Open files in the result list in a suitable application
- \endtable
-
- \image findfiles-example.png Screenshot of the Find Files example
-
-
- \section1 Window Class Definition
-
- The \c Window class inherits QWidget, and is the main application
- widget. It shows the search options and displays the search
- results.
-
- \snippet dialogs/findfiles/window.h 0
-
- The application has two private slots:
- \table
- \row
- \li The \c browse() slot
- \li Called whenever the user wants to browse for a directory to search in
- \row
- \li The \c find() slot
- \li Called whenever the user launches a search with the \uicontrol Find button
- \endtable
-
- In addition we declare several private functions:
-
- \table
- \row
- \li findFiles()
- \li Search for files matching the search parameters
- \row
- \li showFiles()
- \li Display the search result
- \row
- \li ceateButton()
- \li Construct the widget
- \row
- \li createComboBox()
- \li Construct the widget
- \row
- \li createFilesTable()
- \li Construct the widget
- \endtable
-
- \section1 Window Class Implementation
-
- In the constructor we first create the application's widgets.
-
- \snippet dialogs/findfiles/window.cpp 0
-
- We create the widgets to build up the UI, and we add them to a main layout
- using QGridLayout. We have, however, put the \c Find and \c Quit buttons
- and a stretchable space in a separate \l QHBoxLayout first, to make the
- buttons appear in the \c Window widget's bottom right corner.
-
- Alternatively, we could have used Qt Designer to construct a UI file,
- and \l {uic} to generate this code.
-
- \snippet dialogs/findfiles/window.cpp 1
-
- We did not create a \l QMenuBar with a \uicontrol Quit menu item; but we
- would still like to have a keyboard shortcut for quitting. Since we
- construct a \l QShortcut with \l QKeySequence::Quit, and connect it to
- \l QApplication::quit(), on most platforms it will be possible to press
- Control-Q to quit (or whichever standard Quit key is configured on that platform).
- (On \macos, this is redundant, because every application gets a
- \uicontrol Quit menu item automatically; but it helps to make the application portable.)
-
- \snippet dialogs/findfiles/window.cpp 2
-
- The \c browse() slot presents a file dialog to the user, using the
- QFileDialog class. QFileDialog enables a user to traverse the file
- system in order to select one or many files or a directory. The
- easiest way to create a QFileDialog is to use the convenience
- static functions.
-
- Here we use the static QFileDialog::getExistingDirectory()
- function which returns an existing directory selected by the
- user. Then we display the directory in the directory combobox
- using the QComboBox::addItem() function and update the current
- index.
-
- QComboBox::addItem() adds an item to the combobox with the given
- text (if not already present in the list), and containing
- the specified userData. The item is appended to the list of
- existing items.
-
- \snippet dialogs/findfiles/window.cpp 3
-
- The \c find() slot is called whenever the user requests a new
- search by pressing the \uicontrol Find button.
-
- First we eliminate any previous search results by setting the
- table widgets row count to zero. Then we retrieve the
- specified file name, text, and directory path from the respective
- comboboxes.
-
- \snippet dialogs/findfiles/window.cpp 4
-
- We use the directory's path to create a QDir; the QDir class
- provides access to the directory structure and its contents.
-
- We use QDirIterator to iterate over the files that match the
- specified file name and build a QStringList of paths.
-
- Then we search through all the files in the list, using the private
- \c findFiles() function, eliminating the ones that don't contain the
- specified text. We sort them (because QDirIterator did not). And finally,
- we display the results using the private \c showFiles() function.
-
- If the user didn't specify any text, there is no reason to search
- through the files, so we sort and display the results immediately.
-
- \image findfiles_progress_dialog.png Screenshot of the Progress Dialog
-
- \snippet dialogs/findfiles/window.cpp 5
-
- In the private \c findFiles() function we search through a list of
- files, looking for the ones that contain a specified text. This
- can be a very slow operation depending on the number of files as
- well as their sizes. QProgressDialog displays a progress dialog
- if the application has to search through a large number of files,
- or if some of the files have a large size. QProgressDialog can
- also allow the user to abort the operation if it takes too much
- time.
-
- \snippet dialogs/findfiles/window.cpp 6
-
- We run through the files, one at a time, and for each file we
- update the QProgressDialog value. This property holds the current
- amount of progress made. We also update the progress dialog's
- label.
-
- Then we call the QCoreApplication::processEvents() function using
- the QApplication object. In this way we interleave the display of
- the progress made with the process of searching through the files
- so the application doesn't appear to be frozen.
-
- The QApplication class manages the GUI application's control flow
- and main settings. It contains the main event loop, where all
- events from the window system and other sources are processed and
- dispatched. QApplication inherits QCoreApplication. The
- QCoreApplication::processEvents() function processes all pending
- events according to the specified QEventLoop::ProcessEventFlags
- until there are no more events to process. The default flags are
- QEventLoop::AllEvents.
-
- \snippet dialogs/findfiles/window.cpp 7
-
- After updating the QProgressDialog, we open the file in read-only
- mode, and read one line at a time using QTextStream.
-
- The QTextStream class provides a convenient interface for reading
- and writing text. Using QTextStream's streaming operators, you can
- conveniently read and write words, lines and numbers.
-
- For each line we read we check if the QProgressDialog has been
- canceled. If it has, we abort the operation, otherwise we check if
- the line contains the specified text. When we find the text within
- one of the files, we add the file's name to a list of found files
- that contain the specified text, and start searching a new file.
-
- Finally, we return the list of the files found.
-
- \snippet dialogs/findfiles/window.cpp 8
-
- Both the \c findFiles() and \c showFiles() functions are called from
- the \c find() slot. In the \c showFiles() function we run through
- the provided list of file names, adding each relative file name to the
- first column in the table widget and retrieving the file's size using
- QFileInfo for the second column. We use \l QLocale::formattedDataSize()
- to format the file size in a human-readable form. For later use, we set
- the absolute path as a data on the QTableWidget using the
- the role absoluteFileNameRole defined to be Qt::UserRole + 1.
-
- \snippet dialogs/findfiles/window.cpp 17
-
- This allows for retrieving the name of an item using a
- convenience function:
-
- \snippet dialogs/findfiles/window.cpp 18
-
- We also update the total number of files found.
-
- \snippet dialogs/findfiles/window.cpp 10
-
- The private \c createComboBox() function is also called from the
- constructor. We create a QComboBox with the given text, and make it
- editable.
-
- When the user enters a new string in an editable combobox, the
- widget may or may not insert it, and it can insert it in several
- locations, depending on the QComboBox::InsertPolicy. The default
- policy is is QComboBox::InsertAtBottom.
-
- Then we add the provided text to the combobox, and specify the
- widget's size policies, before we return a pointer to the
- combobox.
-
- \snippet dialogs/findfiles/window.cpp 11
-
- The private \c createFilesTable() function is called from the
- constructor. In this function we create the QTableWidget that
- will display the search results. We set its horizontal headers and
- their resize mode.
-
- QTableWidget inherits QTableView which provides a default
- model/view implementation of a table view. The
- QTableView::horizontalHeader() function returns the table view's
- horizontal header as a QHeaderView. The QHeaderView class provides
- a header row or header column for item views, and the
- QHeaderView::setResizeMode() function sets the constraints on how
- the section in the header can be resized.
-
- Finally, we hide the QTableWidget's vertical headers using the
- QWidget::hide() function, and remove the default grid drawn for
- the table using the QTableView::setShowGrid() function.
-
- \snippet dialogs/findfiles/window.cpp 12
-
- \snippet dialogs/findfiles/window.cpp 14
-
- The \c openFileOfItem() slot is invoked when the user double
- clicks on a cell in the table. The QDesktopServices::openUrl()
