Public Functions inherited from QWindowsXPStylePrivate
HBITMAP	buffer (int w=0, int h=0)

void	cleanup (bool force=false)
void	cleanupHandleMap ()
void	drawBackground (XPThemeData &themeData)
	Main theme drawing function. More...
void	drawBackgroundDirectly (XPThemeData &themeData)
	This function draws the theme parts directly to the paintengines HDC. More...
void	drawBackgroundThruNativeBuffer (XPThemeData &themeData)
	This function uses a secondary Native doublebuffer for painting parts. More...
bool	fixAlphaChannel (const QRect &rect)
	When the theme engine paints both a true alpha pixmap and a glyph into our buffer, the glyph might not contain a proper alpha value. More...
bool	hasAlphaChannel (const QRect &rect)
	Returns true if the native doublebuffer contains pixels with varying alpha value. More...

	Returns true if the native doublebuffer contains a pixel which has a non-0xFF alpha value. More...
void	init (bool force=false)
bool	isTransparent (XPThemeData &themeData)

bool	swapAlphaChannel (const QRect &rect, bool allPixels=false)
	Swaps the alpha values on certain pixels: 0xFF?????? -> 0x00?????? 0x00?????? -> 0xFF?????? Used to determin the mask of a non-alpha transparent pixmap in the native doublebuffer, and swap the alphas so we may paint the image as a Premultiplied QImage with drawImage(), and obtain the mask transparency. More...
const QPixmap *	tabBody (QWidget *widget)
	Returns the pointer to a tab widgets body pixmap, scaled to the height of the screen. More...
