The separator has READ and WRITE attributes - and the corresponding functions \c separator() and \c setSeparator(). For - more information on Q_PROPERTY(), refer to \l{Qt's Property System}. - - \section1 TreeModelCompleter Class Implementation - - The first constructor constructs a \c TreeModelCompleter object with a - parent while the second constructor constructs an object with a parent - and a QAbstractItemModel, \a model. - - \snippet examples/tools/treemodelcompleter/treemodelcompleter.cpp 0 - \codeline - \snippet examples/tools/treemodelcompleter/treemodelcompleter.cpp 1 - - The \c separator() function is a getter function that returns the - separator string. - - \snippet examples/tools/treemodelcompleter/treemodelcompleter.cpp 2 - - As mentioned earlier, the \c splitPath() function is reimplemented because - the default implementation is more suited to QDirModel or list models. In - order for QCompleter to split the path into a list of strings that are - matched at each level, we split it using QString::split() with \c sep as its - separator. - - \snippet examples/tools/treemodelcompleter/treemodelcompleter.cpp 3 - - The \c pathFromIndex() function returns data for the completionRole() for a - tree model. This function is reimplemented as its default implementation is - more suitable for list models. If there is no separator, we use - \l{QCompleter}'s default implementation, otherwise we use the - \l{QStringList::prepend()}{prepend()} function to navigate upwards and - accumulate the data. The function then returns a QStringList, \c dataList, - using a separator to join objects of different levels. - - \snippet examples/tools/treemodelcompleter/treemodelcompleter.cpp 4 - - \section1 MainWindow Class Definition - - The \c MainWindow class is a subclass of QMainWindow and implements five - custom slots: \c about(), \c changeCase(), \c changeMode(), - \c highlight(), and \c updateContentsLabel(). - - \snippet examples/tools/treemodelcompleter/mainwindow.h 0 - - In addition, the class has two private functions, \c createMenu() and - \c modelFromFile(), as well as private instances of QTreeView, QComboBox, - QLabel, \c TreeModelCompleter and QLineEdit. - - \snippet examples/tools/treemodelcompleter/mainwindow.h 1 - - \section1 MainWindow Class Implementation - - The \c{MainWindow}'s constructor creates a \c MainWindow object with a - parent and initializes the \c completer and \c lineEdit. The - \c createMenu() function is invoked to set up the "File" menu and "Help" - menu. The \c{completer}'s model is set to the QAbstractItemModel obtained - from \c modelFromFile(), and the \l{QCompleter::highlighted()} - {highlighted()} signal is connected to \c{MainWindow}'s \c highlight() - slot. - - \snippet examples/tools/treemodelcompleter/mainwindow.cpp 0 - - The QLabel objects \c modelLabel, \c modeLabel and \c caseLabel are - instantiated. Also, the QComboBox objects, \c modeCombo and \c caseCombo, - are instantiated and populated. By default, the \c{completer}'s mode is - "Filtered Popup" and the case is insensitive. - - \snippet examples/tools/treemodelcompleter/mainwindow.cpp 1 - \codeline - \snippet examples/tools/treemodelcompleter/mainwindow.cpp 2 - - We use a QGridLayout to place all the objects in the \c MainWindow. - - \snippet examples/tools/treemodelcompleter/mainwindow.cpp 3 - - The \c createMenu() function sets up the QAction objects required and - adds them to the "File" menu and "Help" menu. The - \l{QAction::triggered()}{triggered()} signals from these actions are - connected to their respective slots. - - \snippet examples/tools/treemodelcompleter/mainwindow.cpp 4 - - The \c changeMode() function accepts an \a index corresponding to the - user's choice of completion mode and changes the \c{completer}'s mode - accordingly. - - \snippet examples/tools/treemodelcompleter/mainwindow.cpp 5 - - The \c about() function provides a brief description on the Tree Model - Completer example. - - \snippet examples/tools/treemodelcompleter/mainwindow.cpp 6 - - The \c changeCase() function alternates between \l{Qt::CaseSensitive} - {Case Sensitive} and \l{Qt::CaseInsensitive}{Case Insensitive} modes, - depending on the value of \a cs. - - \snippet examples/tools/treemodelcompleter/mainwindow.cpp 7 - - \section1 \c main() Function - - The \c main() function instantiates \c MainWindow and invokes the - \l{QWidget::show()}{show()} function to display it. - - \snippet examples/tools/treemodelcompleter/main.cpp 0 -*/ |
