undermouse() function not working

[wysota]

Retrieve the event position from the event object and then test whether the rect() of the class contains the position of the event, like so:

void someClass::mousePressEvent(QMouseEvent *me){
  QPoint pos = me->pos();
  if(stackedwidget->rect().contains(pos)){
    qDebug("STACK WIDGET HERE");
  }
}

void someClass::mousePressEvent(QMouseEvent *me){
  QPoint pos = me->pos();
  if(stackedwidget->rect().contains(pos)){
    qDebug("STACK WIDGET HERE");
  }
}

To copy to clipboard, switch view to plain text mode 

Note that this will not work if the child widget you want to test against handles the mouse press event itself (like QListView probably does). In that situation you have to reimplement the event in the widget in question or apply an event filter on the child widget to monitor its events. See the docs for reference on event filters.

thank u wysota
is there any way to stop all the widgets in the main window receiving events
and all the events should be send by mainwindow.
i know event filter may do this but main window must require knowledge of its child widgets, is it possible to stop the events of the childs without the knowldege of the number of childs the main window has.

AFAIK you can get *all* events by installing the eventfilter on qApp. This way you could get all events from all widgets. Be sure to pass on the events you are not interested in.
