Set the text in the slot for QAction::trigerred signal.
something like -

void someClass::someSlot()
{
     QAction *action = (QAction*)sender();
     action->setText( action->text() == "Open" ?  "Close" : "Open" );
}

void someClass::someSlot()
{
     QAction *action = (QAction*)sender();
     action->setText( action->text() == "Open" ?  "Close" : "Open" );
}

To copy to clipboard, switch view to plain text mode

Hi Aamer,
Thanks for replying to this message. Actually I need to implement toggle action for context menu. But only one text can be added to QAction, like QAction( _icon, _text, _parent ). In my case i need both "Open" and "Close" for the same action. But it should be toggled. Can u tell me how to implement.

How are you showing the context menu ? You must be adding some actions to it somewhere ?

I'm creating like following

Action::Action( enum , const QIcon & icon, const QString & text,
                                QObject * parent, int ) :
QAction( icon, text, parent ),
{
}
 
Action class is derived from QAction.
 
creation of menu action for contextmenu device
--------
createMethode()
{
	QMenu * menu = new QMenu( _parent );
 
    menu->addAction( new Action( enum value, QIcon(), tr( "Open" ), menu ) );
}

Action::Action( enum , const QIcon & icon, const QString & text,
                                QObject * parent, int ) :
QAction( icon, text, parent ),
{
}

Is there a reason to inherit QAction ??
What I want to know is how you are showing menu. You need to simply follow the following steps -

QAction *action = new QAction("Open");
connect(action,trigerred(bool), someClass, mySlot(bool) );
// Add action to any menu u want... when that action is triggered you will reach mySlot function.
// Before I gave hint what to do in mySlot.

QAction *action = new QAction("Open");
connect(action,trigerred(bool), someClass, mySlot(bool) );
// Add action to any menu u want... when that action is triggered you will reach mySlot function.
// Before I gave hint what to do in mySlot.

Hope you can now join the pieces together

or you can just create 2 actions one for open and other for close. Store a flag somewhere which according to the current state of your application and just before you show your menu , hide the appropriate action.
