[QtEmbedded] Translucent QGraphicsView with animated child widgets

[zuck]

Yeah! This is the final working code (Qt 4.6):

#include <QtGui/QDesktopWidget>
#include <QtGui/QApplication>
 
MainWindow::MainWindow(QWidget* parent)
    :   QmlView(parent) // or QGraphicsView...
{
    this->setWindowFlags(Qt::FramelessWindowHint);
    this->setCacheMode(QGraphicsView::CacheBackground);
}
 
void MainWindow::showEvent(QShowEvent* event)
{ 
    WId wid = QApplication::desktop()->winId();
 
    int x = this->x();
    int y = this->y();
    int w = this->width();
    int h = this->height();
 
    this->setBackgroundBrush(QPixmap::grabWindow(wid, x, y, w, h));
 
    QmlView::showEvent(event);
}

#include <QtGui/QDesktopWidget>
#include <QtGui/QApplication>

MainWindow::MainWindow(QWidget* parent)
    :   QmlView(parent) // or QGraphicsView...
{
    this->setWindowFlags(Qt::FramelessWindowHint);
    this->setCacheMode(QGraphicsView::CacheBackground);
}

void MainWindow::showEvent(QShowEvent* event)
{ 
    WId wid = QApplication::desktop()->winId();
    
    int x = this->x();
    int y = this->y();
    int w = this->width();
    int h = this->height();
    
    this->setBackgroundBrush(QPixmap::grabWindow(wid, x, y, w, h));

    QmlView::showEvent(event);
}

No "WA_TranslucentBackground" or "autoFillBackground(false)" are needed!
