C++ (Cpp) QEglContext::swapBuffers Examples

Example #1

void QVGLiteWindowSurface::flush(QWidget *widget, const QRegion &region, const QPoint &offset)
{
    Q_UNUSED(widget);
    Q_UNUSED(region);
    Q_UNUSED(offset);
    QEglContext *context = graphicsSystem->context;
    if (context) {
        if (!isPaintingActive)
            qt_vg_make_current(context, graphicsSystem->rootWindow);
        context->swapBuffers();
        qt_vg_done_current(context);
        context->setSurface(EGL_NO_SURFACE);
        isPaintingActive = false;
    }
}
