◆ buffer()

HBITMAP QQC2::QWindowsXPStylePrivate::buffer	(	int	w = 0,
		int	h = 0 )

Returns a native buffer (DIB section) of at least the size of ( x , y ). The buffer has a 32 bit depth, to not lose the alpha values on proper alpha-pixmaps.

◆ drawBackground()

bool QQC2::QWindowsXPStylePrivate::drawBackground	(	XPThemeData &	themeData,
		qreal	correctionFactor = 1 )

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.

◆ drawBackgroundDirectly()

bool QQC2::QWindowsXPStylePrivate::drawBackgroundDirectly	(	HDC	dc,
		XPThemeData &	themeData,
		qreal	additionalDevicePixelRatio )

This function draws the theme parts directly to the paintengines HDC. Do not use this if you need to perform other transformations on the resulting data.

Definition at line 647 of file qquickwindowsxpstyle.cpp.

References QQC2::XPThemeData::painter, QQC2::XPThemeData::partId, QPaintEngine::QPainter, and QQC2::XPThemeData::stateId.

◆ drawBackgroundThruNativeBuffer()

bool QQC2::QWindowsXPStylePrivate::drawBackgroundThruNativeBuffer	(	XPThemeData &	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 (horizonal 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).

Here is the call graph for this function:

◆ fixAlphaChannel()

bool QQC2::QWindowsXPStylePrivate::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 occures.

◆ hasAlphaChannel()

bool QQC2::QWindowsXPStylePrivate::hasAlphaChannel ( const QRect & rect )

Returns true if the native doublebuffer contains pixels with varying alpha value.

◆ swapAlphaChannel()

bool QQC2::QWindowsXPStylePrivate::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.

This function will always return a valid window handle, and might create a limbo widget to do so. We often need a window handle to for example open theme data, so this function ensures that we get one.
