# A Tiny Example Featuring a Toggle Action

This example program demonstrates the use of QAction in its incarnation as a toggle action.

Main:

    #include <qapplication.h>
    #include <qmainwindow.h>
    #include <qtoolbar.h>
    #include <qaction.h>

    #include "labelonoff.xpm"

    int main( int argc, char **argv )
    {
        QApplication app( argc, argv );
        QMainWindow * window = new QMainWindow;
        window->setCaption("Qt Example - Toggleaction");
        QToolBar * toolbar = new QToolBar( window );

        QAction * labelonoffaction = new QAction( window, "labelonoff", TRUE );

        labelonoffaction->setText( "labels on/off" );
        labelonoffaction->setAccel( Qt::ALT+Qt::Key_L );
        labelonoffaction->setIconSet( (QPixmap) labelonoff_xpm );

        QObject::connect( labelonoffaction, SIGNAL( toggled( bool ) ),
                          window, SLOT( setUsesTextLabel( bool ) ) );

        labelonoffaction->addTo( toolbar );

        app.setMainWidget( window );
        window->show();
        return app.exec();
    }
