Member Function Documentation

◆ animationTime()

QTime QWindowsVistaStylePrivate::animationTime ( ) const

Animations are started at a frame that is based on the current time, which makes it impossible to run baseline tests with this style. Allow overriding through a dynamic property.

Here is the call graph for this function:

◆ buffer()

HBITMAP QWindowsVistaStylePrivate::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.

static

Definition at line 306 of file qwindowsvistastyle.cpp.

◆ drawBackground()

bool QWindowsVistaStylePrivate::drawBackground	(	QWindowsThemeData &	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.

Definition at line 622 of file qwindowsvistastyle.cpp.

References QPaintEngine::QPainter, and QPainter::QWidget.

Here is the call graph for this function:

◆ drawBackgroundDirectly()

bool QWindowsVistaStylePrivate::drawBackgroundDirectly	(	HDC	dc,
		QWindowsThemeData &	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 681 of file qwindowsvistastyle.cpp.

References QPaintEngine::QPainter.

Here is the call graph for this function:

◆ 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).

Here is the call graph for this function:

◆ 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.

static

Definition at line 254 of file qwindowsvistastyle.cpp.

◆ hasAlphaChannel()

bool QWindowsVistaStylePrivate::hasAlphaChannel ( const QRect & rect )

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

◆ isTransparent()

bool QWindowsVistaStylePrivate::isTransparent ( QWindowsThemeData & themeData )

Returns true if the part contains any transparency at all. This does not indicate what kind of transparency we're dealing with. It can be

Alpha transparency
Masked transparency

Definition at line 461 of file qwindowsvistastyle.cpp.

◆ pixelMetricFromSystemDp()

◆ region()

QRegion QWindowsVistaStylePrivate::region ( QWindowsThemeData & themeData )

Returns a QRegion of the region of the part

Definition at line 471 of file qwindowsvistastyle.cpp.

◆ swapAlphaChannel()

bool QWindowsVistaStylePrivate::swapAlphaChannel	(	const QRect &	rect,
		bool	allPixels = false )

Swaps the alpha values on certain pixels: 0xFF?????? -> 0x00?????? 0x00?????? -> 0xFF?????? Used to determine 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.

◆ winId()

HWND QWindowsVistaStylePrivate::winId ( const QWidget * widget )

static

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.
