[Qt-interest] repaint not working

[Malyushytsky, Alex]

Minimum compilable example may help to find a problem.
At least without seen all the code I am only able to tell that neither update or  repaint should not be required,
cause update should be scheduled  ( and executed as soon event loop gets to it ) by

setUpdatesEnabled(true);

Subject: [Qt-interest] repaint not working

We have a project that 3 people are working on. The repaint works in the Mac. the same code compiled on Ubuntu does not work.


{

    connect(this, SIGNAL(pointChanged()), this, SLOT(repaint()));

}





...


    qDebug() << "I'm  trying to paint 0000000000000";

    if ( newPoint != oldPoint ) {

        m_input_map->getSet(m_held_set)->setPoint(m_sets_point, newPoint);

               setUpdatesEnabled(true);

         //   emit pointChanged();

        //      emit repaint();

               QWidget::repaint() ;

               qDebug() << "I'm  trying to paint";

    }

    qDebug() << "Set:" << m_held_set << " Point:" << m_sets_point;

    qDebug() << "At:" << event->pos();







As you can see I have been trying different thing to see if I can get it to work.

This code is executed as the debug messages are see.



The changes that the code makes the the view are there, as they can be seen by forcing a system repaint by moving a different window over this one and then moving it away.



When the window is thus redisplayed the changes that were expected are there.





So --- why on Ubuntu it won't repaint?  As I said it works on a Mac.
