QScroller prevent button click

MajidKamali

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?

SGaist

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.

SGaist

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.
