How to Add Options Menu in Symbian Application
Options menu and Exit button can be attached to "QMainWindow":http://doc.qt.nokia.com/latest/qmainwindow.html, "QDialog":http://doc.qt.nokia.com/latest/qdialog.html or to "QWidget":http://doc.qt.nokia.com/latest/qwidget.html on Symbian. QMainWindow has predefined Symbian CBA buttons but they have to be defined for QDialog and QWidget.
Preconditions
Make sure that the status pane and the control pane of the application are enabled. To do it call method showMaximized() of the main window:
<br />int main(int argc, char *argv[])<br />{<br /> QApplication app(argc, argv);
MainWindow mainWindow;<br /> mainWindow.showMaximized();
return app.exec&amp;#40;&#41;;<br />}<br />
QMainWindow has predefined Symbian CBA buttons so different options can be added to the Options menu by adding a new action.
menuBar()<s>>addAction("Example&quot;, this, SLOT (exampleSlot())); <code>
<br />Please note that '''exampleSlot()''' slot is called when an item is selected from the Options menu and its behavior should be also implemented.
<br />h2. Defining menus in QDialog or QWidget
<br />Symbian CBA buttons are not predefined for QDialog or QWidget and they have to be defined.
<br />An instance of "QMenu&quot;:http://doc.qt.nokia.com/latest/qmenu.html should be added at the header:
<br />
QMenu* m_pMenu;
At appropriate location should be added the implementation of Options menu and the Exit button:
<br />// Create menu<br />m_pMenu = new QMenu(this);<br />m_pMenu</s>>addAction("Example&quot;, this, SLOT (exampleSlot()));
// Create Options CBA<br />QAction *pOptions = new QAction("Options&quot;, this);<br />// Set defined menu into Options button<br />pOptions->setMenu(m_pMenu);<br />pOptions->setSoftKeyRole(QAction::PositiveSoftKey);<br />addAction(pOptions);
// Create Exit CBA<br />QAction *pExitButton = new QAction(QString("Exit&quot;), this);<br />pExitButton->setSoftKeyRole(QAction::NegativeSoftKey);<br />// Exit button closes the application<br />QObject::connect(pExitButton, SIGNAL (triggered()),<br />QApplication::instance(), SLOT (quit()));<br />addAction(pExitButton);<br />
Of course the right button can be used not only to close the application as it can be connected to other slot.
