Hi,

Currently my application repeatedly plots points to the canvas, and I need to be able to select one of the points while new points are still being plotted. This is fine when WA_PaintOutsidePaintEvent is set to false. However, when I set it to true:

canvas()->setAttribute(WA_PaintOutsidePaintEvent, true);

The QEvent::MouseButtonPress inside of the EventFilter in CanvasPicker does not get activated until the points stop plotting. Furthermore, the QEvent::MouseMove event still gets triggered even when the points are still plotting. Here is the EventFilter function:

Qt Code: 
  1. bool CanvasPicker::eventFilter(QObject *object, QEvent *e)
  2. {
  3.  
  4.     if ( object != (QObject *)plot()->canvas() )
  5.         return false;
  6.  
  7.     switch(e->type())
  8.     {
  9.         case QEvent::FocusIn:
  10.             showCursor(true);
  11.         case QEvent::FocusOut:
  12.             showCursor(false);
  13.  
  14.         case QEvent::Paint:
  15.         {   
  16.             QApplication::postEvent(this, new QEvent(QEvent::User));
  17.             break;
  18.         }
  19.         case QEvent::MouseButtonPress:
  20.         {
  21.           // Only capture left click
  22.           if (((QMouseEvent *)e)->button() == (Qt::LeftButton))
  23.           {
  24.             select(((QMouseEvent *)e)->pos(), ((QMouseEvent *)e)->globalPos());
  25.             return true; 
  26.           }
  27.         }
  28.         // Gets called each time mouse is moved on canvas
  29.         case QEvent::MouseMove:
  30.         {
  31.             return true; 
  32.         }
  33.  
  34.         default:
  35.             break;
  36.     }
  37.     return QObject::eventFilter(object, e);
  38. }
To copy to clipboard, switch view to plain text mode 

Can somebody please tell me how to get around this problem? (So I want to set WA_PaintOutsidePaintEvent true and have QEvent::MouseButtonPress get triggered while points are continuously plotting on the graph) Thank you.
