hi all,

i m facing a strange problem. i have made a custom toolkit by doing some general drawing. The basic purpose is to show this tooltip when the mouse hovers over a widget and hide it when the cursor is removed off this widget. So, i showed the tooltip when the mouse hovers over the widget and hide it when the mouse is taken off it. Here is the code:
Qt Code: 
  1. bool CPreviewLeftWidget::eventFilter(QObject *obj, QEvent *event)
  2.     {
  3.         if (obj == m_plblIconInfo) {
  4.             if (event->type() == QEvent::HoverEnter) 
  5. 			{
  6.                 CToolTip::showTip(m_plblIconInfo,tr("PreviewLeftWidget_Manual_Positioning_Heading"),tr("PreviewLeftWidget_Manual_Positioning_Tooltip"));
  7. 			    m_bHovered = TRUE;
  8.                 return true;
  9.             } 
  10. 			if(event->type() == QEvent::HoverLeave)
  11. 		    {
  12. 				CToolTip::onMouseLeave();
  13. 				m_bHovered = FALSE;
  14.                 return true;
  15.             }
  16.  
  17. 			else {
  18.             // pass the event on to the parent class
  19.             return QWidget::eventFilter(obj, event);
  20.         }
  21. 		}
  22.     }

The problem is that QHoverLeave event is sent even when the mouse is still over the widget...which causes a blinking effect. Here is the showTip and drawing used:
Qt Code: 
  1. void CToolTip::showTip(QWidget* widget,QString heading,QString tip)
  2. {
  3. 	if(m_pGlobalToolTip == NULL )
  4. 		m_pGlobalToolTip = new CToolTip(widget,heading,tip);
  5.  
  6.     m_pGlobalToolTip->setToolTip(heading, tip);
  7.  
  8. 	if(widget == NULL )
  9. 	{
  10. 		return;
  11. 	}
  12. 	QRect rect = widget->rect();
  13. 	QPoint point = widget->mapToGlobal(widget->rect().topLeft());
  14. 	int rect_height = rect.height();
  15. 	int rect_width = rect.width();
  16.  
  17. 	int tooltip_width = m_pGlobalToolTip->getWidth();
  18.  
  19. 	int xpos;
  20.     int ypos;
  21.  
  22. 	if(m_pGlobalToolTip->isShownOnRight(widget))
  23. 	{
  24. 		xpos = point.x() + rect_width + 5 ;
  25. 		if(xpos < 0)
  26. 			xpos = 0;
  27.  
  28. 		ypos = point.y() + (rect_height/2) - 26 - CORNER_RADIUS;
  29. 		if(ypos < 0)
  30. 			ypos = 0;
  31. 	}
  32. 	else
  33. 	{
  34. 		xpos = point.x() - tooltip_width - 5;
  35. 		if(xpos < 0)
  36. 			xpos = 0;
  37.  
  38. 		ypos = point.y() + (rect_height/2) - 26 - CORNER_RADIUS;
  39. 		if(ypos < 0)
  40. 			ypos = 0;
  41. 	}
  42.  
  43.  
  44. 	QPoint pos(xpos, ypos);
  45. 	m_pGlobalToolTip->showToolTip(pos);
  46. }

is this behaviour occuring cuz i do the drawing outside the widget's rectangle which causes QHoverLeave to occur...if this is so, how to stop it . I m on a tight deadline..so i would reallly appreciate a brisk reply or any kind of opinion!!!
