Functions

◆ createPixmapData()

QPixmapData * QMinimalIntegration::createPixmapData ( QPixmapData::PixelType  type) const
virtual

Factory function for QPixmapData.

PixelType can be either PixmapType or BitmapType.

◆ createPlatformWindow()

QPlatformWindow * QMinimalIntegration::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.

◆ createWindowSurface()

QWindowSurface * QMinimalIntegration::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.

◆ hasCapability()

bool QMinimalIntegration::hasCapability ( QPlatformIntegration::Capability  cap) const
virtual

Reimplemented from QPlatformIntegration.

virtual bool hasCapability(Capability cap) const

◆ screens()

QList<QPlatformScreen *> QMinimalIntegration::screens ( ) const
inlinevirtual

Accessor function to a list of all the screens on the current system.

The screen with the index == 0 is the default/main screen.

Implements QPlatformIntegration.
