How to get the object on which mouse is released?
Message 1 in thread
Hi All,
I have a small doubt here.
How to get the object on which mouse is released?
In my code I am performing a mousePressEvent on a button(say button1)
and mouseReleaseEvent on another button(say button2). The problem here
is I am not able to access the button on which mouseReleaseEvent is
performed (ie .not able to access button2) instead it is referring to
button1.
I tried with the below code but it is not working.
Void mouseReleaseEvent(QMouseEvent *event)
{
If(event->button==4)
{
QString str;
str=this->text();
Printf("str : %s\n",str.toLatin1().data());
}
}
But in the above code "this pointer" is referring to the object on which
the mousePressEvent happened. so how to get the object on which the
mouse is released?
Regards
Naveen

But QApplication::widgetAt(event->globalPos()) function returns a QWidget but I want a QPushButton so that I can access the text of the button.
So how to get the button(QPuhButton) when a mouseReleaseEvent happens.

See qobject_cast.
Please don't post HTML messages, it hurts! Use plain text.
