    Hi
    I have a QGraphicsView and it has many buttons
    I created a QScroller which grabs LeftMouseButton for scrolling
    but buttons can not be clicked

    How can I fix this?

    Thanks

      Hi,

      As silly as it may sound: release the mouse grab from your scroller.

        @SGaist Sorry, I did not understand what you said
        What do you mean by releasing mouse grab?
        Where and how I should do this?

          Can you share the code where you setup your QScroller ? We might be talking about two different things.

            @SGaist
            In ctor of my window which contains a QGraphicsView:
            QScroller *scroller = QScroller::grabGesture(graphicsView, QScroller::LeftMouseButtonGesture);
            in graphicsView, there are multiple buttons. but buttons are not clickeable when I add above line.

              Ok, can you provide a minimal compilable example that shows that behavior ?

                @SGaist Sorry, I removed my old code, but this is psudo code of what I did:

                QList<QList<QPushButton*>> buttons;
                for(int i = 0; i < 4; i++)
                   for(int j = 0; j < 10; j++)
                   {
                      // set size
                      // set position in scene
                      // add to scene
                   }
                
                // change scene rect, based on buttons positions, with some margin
                
                QScroller *scroller = QScroller::grabGesture(graphicsViewPointer, QScroller::LeftMouseButtonGesture);
                

                By adding last line, I can kinetic scroll the graphicsView with mouse, but I can not click buttons

                  The problem with pseudo code is that I can't reproduce your setup so I can't test in the same condition as you do.
