Functions

◆ clipboard()

QPlatformClipboard * QXlibIntegration::clipboard ( ) const

virtual

Accessor for the platform integrations clipboard.

Default implementation returns a default QPlatformClipboard.

See also: QPlatformClipboard

Reimplemented from QPlatformIntegration.

Definition at line 134 of file qxlibintegration.cpp.

Referenced by screens().

 {
     //Use lazy init since clipboard needs QTestliteScreen

         that->mClipboard = new QXlibClipboard(mPrimaryScreen);
     }
     return mClipboard;
 }

◆ createPixmapData()

QPixmapData * QXlibIntegration::createPixmapData ( QPixmapData::PixelType type ) const

virtual

Factory function for QPixmapData.

PixelType can be either PixmapType or BitmapType.

Implements QPlatformIntegration.

Definition at line 85 of file qxlibintegration.cpp.

 {
 #ifndef QT_NO_OPENGL
     if (mUseOpenGL)

 #endif
     return new QRasterPixmapData(type);
 }

◆ createPlatformWindow()

QPlatformWindow * QXlibIntegration::createPlatformWindow	(	QWidget *	widget,
		WId	winId
	)		const

virtual

Factory function for QPlatformWindow.

The widget parameter is a pointer to the top level widget(tlw) which the QPlatformWindow is suppose to be created for. The WId handle is actually never used, but there for future reference. Its purpose is if it is going to be possible to create QPlatformWindows on existing WId.

All tlw has to have a QPlatformWindow, and it will be created when the QPlatformWindow is set to be visible for the first time. If the tlw's window flags are changed, or if the tlw's QPlatformWindowFormat is changed, then the tlw's QPlatformWindow is deleted and a new one is created.

Implements QPlatformIntegration.

Definition at line 104 of file qxlibintegration.cpp.

 {
     return new QXlibWindow(widget);
 }

◆ createWindowSurface()

QWindowSurface * QXlibIntegration::createWindowSurface	(	QWidget *	widget,
		WId	winId
	)		const

virtual

Factory function for QWindowSurface.

The QWidget parameter is a pointer to the top level widget(tlw) the window surface is created for. A QPlatformWindow is always created before the QWindowSurface for tlw where the widget also requires a WindowSurface. It is possible to create top level QWidgets without a QWindowSurface by specifying QPlatformWindowFormat::setWindowSurface(false) for the tlw QPlatformWindowFormat.

See also: QWindowSurface; createPlatformWindow(QWidget *widget, WId winId = 0) const

Implements QPlatformIntegration.

 #ifndef QT_NO_OPENGL

         return new QGLWindowSurface(widget);
 #endif
     return new QXlibWindowSurface(widget);
 }

◆ fontDatabase()

QPlatformFontDatabase * QXlibIntegration::fontDatabase ( ) const

virtual

◆ grabWindow()

QPixmap QXlibIntegration::grabWindow	(	WId	window,
		int	x,

		int	height
	)		const
