Functions

clipboard()

QPlatformClipboard * QWaylandIntegration::clipboard ( ) const

virtual

Accessor for the platform integrations clipboard.

Default implementation returns a default QPlatformClipboard.

QPlatformClipboard

Reimplemented from QPlatformIntegration.

Definition at line 138 of file qwaylandintegration.cpp.

{
    if (!mClipboard)
        mClipboard = new QWaylandClipboard(mDisplay);
    return mClipboard;
}

createPixmapData()

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

virtual

Factory function for QPixmapData.

PixelType can be either PixmapType or BitmapType.

See also

QPixmapData

Implements QPlatformIntegration.

Definition at line 92 of file qwaylandintegration.cpp.

{
#ifdef QT_WAYLAND_GL_SUPPORT
    if (mUseOpenGL)
        return new QGLPixmapData(type);
#endif
    return new QRasterPixmapData(type);
}

createPlatformWindow()

QPlatformWindow * QWaylandIntegration::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.

QPlatformWindow, QPlatformWindowFormat

createWindowSurface(QWidget *widget, WId winId) const

Implements QPlatformIntegration.

Definition at line 101 of file qwaylandintegration.cpp.

{
    Q_UNUSED(winId);
#ifdef QT_WAYLAND_GL_SUPPORT
    bool useOpenGL = mUseOpenGL || (widget->platformWindowFormat().windowApi() == QPlatformWindowFormat::OpenGL);
    if (useOpenGL)
        return mDisplay->eglIntegration()->createEglWindow(widget);
#endif
    return new QWaylandShmWindow(widget);
}

createWindowSurface()

QWindowSurface * QWaylandIntegration::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.

    Q_UNUSED(winId);
#ifdef QT_WAYLAND_GL_SUPPORT

    if (useOpenGL)
        return new QWaylandGLWindowSurface(widget);
#endif
    return new QWaylandShmWindowSurface(widget);
}

fontDatabase()

QPlatformFontDatabase * QWaylandIntegration::fontDatabase ( ) const

virtual

Accessor for the platform integrations fontdatabase.

Default implementation returns a default QPlatformFontDatabase.

QPlatformNativeInterface * QWaylandIntegration::nativeInterface ( ) const

virtual

Reimplemented from QPlatformIntegration.

Definition at line 72 of file qwaylandintegration.cpp.

{
    return mNativeInterface;

screens()

QList< QPlatformScreen * > QWaylandIntegration::screens ( ) const

virtual

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