Problem to recover an object via a QAction

[Potch]

Hello,

I have several QPushButtons on which I added the same contextual menu this way :

setContextMenuPolicy(Qt::ActionsContextMenu);
QAction* MyAction = new QAction("DoThis");
connect(MyAction, SIGNAL(triggered()), this, SLOT(MySlot()));
addAction(MyAction);

setContextMenuPolicy(Qt::ActionsContextMenu);
QAction* MyAction = new QAction("DoThis");
connect(MyAction, SIGNAL(triggered()), this, SLOT(MySlot()));
addAction(MyAction);

To copy to clipboard, switch view to plain text mode 

For every button, there's a contextual menu with the same action. This action is connected to one slot. This slot has to behave differently regarding to the sender.

So far I can easily recover the occurrence of the button the user clicked on using :

QPushButton* PB = qobject_cast<QPushButton*>( sender() );
PB->etc...

QPushButton* PB = qobject_cast<QPushButton*>( sender() );
PB->etc...

To copy to clipboard, switch view to plain text mode 

My problem is to recover the occurence of the button on which the user used the contextual menu. For QAction inherits QObject, I tried

QAction* TheAction= qobject_cast<QAction*>( sender() );

QAction* TheAction= qobject_cast<QAction*>( sender() );

To copy to clipboard, switch view to plain text mode 

But then how to make the link between the QAction and the QPushButton ?
I associated the same action to all the buttons. Is it a problem ?

Please feel free to ask me if I didn't made myself clear.
Thanks in advance.

How about QAction::setData?
You can set some specific data (an enum perhaps), when you create and add the action, later you can retrieve it.


(PS: Personally I do not really like using sender() etc. and prefer using QSignalMapper if necessary.)

Thanks for your advice caduel, I'm seeing how I can implement it this way...
