Functions

createPixmapData()

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

virtual

Factory function for QPixmapData.

PixelType can be either PixmapType or BitmapType.

QPixmapData

Implements QPlatformIntegration.

Definition at line 110 of file qdirectfbintegration.cpp.

{
    if (type == QPixmapData::BitmapType)
        return new QRasterPixmapData(type);
    else
        return new QDirectFbBlitterPlatformPixmap;
}

createPlatformWindow()

QPlatformWindow * QDirectFbIntegration::createPlatformWindow ( QWidget *  widget, WId  winId = 0  ) 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.

QPlatformWindow, QPlatformWindowFormat

createWindowSurface(QWidget *widget, WId winId) const

Implements QPlatformIntegration.

Definition at line 118 of file qdirectfbintegration.cpp.

{
    return new QDirectFbWindow(window,m_input.data());
}

createWindowSurface()

QWindowSurface * QDirectFbIntegration::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.

}

fontDatabase()

QPlatformFontDatabase * QDirectFbIntegration::fontDatabase ( ) const

virtual
