how can I hide a widget that generated a signal in qt

Let's say we have more than one widgets and all of them have main menu button. so I connected all of the main menu buttons clicked signal to one slot, which is supposed to h

connect(widget1->mainMenuButton, SIGNAL(clicked()),this, SLOT(mainClicked()));
connect(widget1->mainMenuButton, SIGNAL(clicked()),this, SLOT(mainClicked()));

and I have

private slots:
    void mainClicked();

in mainClicked I want to hide whoever triggered the clicked signal. frame1 or frame2 in the above example.

I could use sender() to retrieve the QObject that triggered the signal but then how can I call hide which is QWidget function?

your help is appreciated.

Solution

  • I think this should work:

    dynamic_cast<QWidget*>(sender()) -> hide() ;
