Main theme drawing function. Determines the correct lowlevel drawing method depending on several factors. Use drawBackgroundThruNativeBuffer() if:

Painter does not have an HDC
Theme part is flipped (mirrored horizontally) else use drawBackgroundDirectly().
Note
drawBackgroundThruNativeBuffer() can return false for large sizes due to buffer()/CreateDIBSection() failing.

◆ drawBackgroundThruNativeBuffer()

bool QWindowsVistaStylePrivate::drawBackgroundThruNativeBuffer	(	QWindowsThemeData &	themeData,
		qreal	additionalDevicePixelRatio,
		qreal	correctionFactor )

This function uses a secondary Native doublebuffer for painting parts. It should only be used when the painteengine doesn't provide a proper HDC for direct painting (e.g. when doing a grabWidget(), painting to other pixmaps etc), or when special transformations are needed (e.g. flips (horizontal mirroring only, vertical are handled by the theme engine).

correctionFactor is an additional factor used to scale up controls that are too small on High DPI screens, as has been observed for WP_MDICLOSEBUTTON, WP_MDIRESTOREBUTTON, WP_MDIMINBUTTON (QTBUG-75927).

◆ fixAlphaChannel()

bool QWindowsVistaStylePrivate::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. The rule of thumb for premultiplied pixmaps is that the color values of a pixel can never be higher than the alpha values, so we use this to our advantage here, and fix all instances where this occurs.
