Description
Qt allows using a context-sensitive menu to be shown in the control pane area that changes dynamically based on the focused widget. This is done by assigning softkeys (see QWidget::setSoftKeys() for a widget. By default, a menu item for Actions (see QWidget::actions()) is added in a focused widget's options menu.
This behavior can be changed by controlling context menu policy of a widget, a property that holds how the widget shows a context menu.
Source code
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
textEditor = new QTextEdit(tr("Hello"), this);
// Set context menu policy to 'none' to prevent Actions menu from being shown
textEditor->setContextMenuPolicy(Qt::NoContextMenu);
// Set softkeys to text editor for a context-sensitive menu
QAction* options = new QAction(tr("Options"), this);
options->setSoftKeyRole(QAction::MenuSoftKey);
QAction* exit = new QAction(tr("Exit"), this);
exit->setSoftKeyRole(QAction::ExitSoftKey);
QList<QAction*> textEditorSoftKeys;
textEditorSoftKeys.append(options);
textEditorSoftKeys.append(exit);
textEditor->setSoftKeys(textEditorSoftKeys);
setCentralWidget(textEditor);
// Add any common menu items into menu bar
fileMenu = menuBar()->addMenu(tr("&File"));
exit = new QAction(tr("&Exit"), this);
fileMenu->addAction(exit);
connect(exit, SIGNAL(triggered()), this, SLOT(close()));
}
Postconditions
Text editor has a menu without any visible Actions items.
