Hi

Using Qt3.3.3. I have a QToolbutton derive class where I am trying use a style to help the button to conform to OS GUI used. I can set the QStyle drawPrimitive or QStyle drawComplex so the graphic is what I want however I cannot change the colour to indicate for example hover or mouse click.

Qt Code: 
  1. //++ ------------------------------------------------------------------------------------
  2. void RDWinWithWinMenuBtn_c::paintEvent( QPaintEvent * /*vpEvent*/ )
  3. {
  4. 	// RD_DEV_IOR_FACT
  5. 	// The colorGroup parameter in drawComplexControl appears not to be used (look at Qt source code)
  6. 	// so doing this 
  7. 	// QColorGroup colorGrp; <- default all black
  8. 	// makes not difference to the button color!!
  9. 	//
  10. 	// Also style does not change when windows theme changes. Is this not the idea of QStyles?
  11.  
  12. 	QPainter painter( this );
  13. 	//style().drawComplexControl( QStyle::CC_ToolButton, &painter, this, rect(), colorGroup() );
  14.  
  15.          // Test code to change to ANY color or style! Not!
  16. 	QStyle::SFlags sf = QStyle::Style_Raised;
  17. 	QPalette pl = palette();
  18. 	QColorGroup cga = pl.active();
  19. 	QColorGroup cgi = pl.inactive();
  20. 	QColorGroup cgBtn;
  21. 	if( hasMouse() )
  22. 	{
  23. 		if( m_bBtnIsClicked )
  24. 		{
  25. 			sf = QStyle::Style_Down;
  26. 			cga.setColor( QColorGroup::Background, QColor( Qt::green ) );
  27. 			cgBtn = cga;
  28. 		}
  29. 		else
  30. 		{
  31. 			sf = QStyle::Style_HasFocus;
  32. 			cgi.setColor( QColorGroup::Background, QColor( Qt::blue ) );
  33. 			cgBtn = cgi;
  34. 		}
  35. 	}
  36.  
  37. 	pl.setActive( cga );
  38. 	pl.setInactive( cgi );
  39. 	setPalette( pl );
  40. 	style().drawControl( QStyle::CE_PushButton, &painter, this, rect(), cgBtn, sf );
  41. }
  42.  
  43. void RDWinWithWinMenuBtn_c::mousePressEvent( QMouseEvent * vpEvent )
  44. {
  45. 	m_bBtnIsClicked = true;
  46. }
  47.  
  48. void RDWinWithWinMenuBtn_c::mouseReleaseEvent( QMouseEvent * vpEvent )
  49. {
  50. 	m_bBtnIsClicked = false;
  51. }

How do I get the style colour to be used? ATM I see a button but it does not 'animate' to show the user it is active or clicked on. It makes no difference what a style flag or colorGroup I feed it.
