Rotate QGraphicsProxyWidget in QGraphicsView

[wysota]

What if you get rid of the "wi" widget and the layout? What if you call rotate() instead of setRotation()?

#include <QtCore>
#include <QtGui>
 
int main(int argc, char **argv)
{
	QApplication a(argc, argv);
	QGraphicsView gv;
	QGraphicsScene scene(-200,-200,400,400);
	gv.setScene(&scene);
	gv.setRenderHint(QPainter::Antialiasing);
    gv.setDragMode(QGraphicsView::ScrollHandDrag);
 
	QPushButton btn("My Button");
    QGraphicsProxyWidget *pw = scene.addWidget(&btn);
    pw->setPos(0, 0);
    pw->rotate(-20);
    gv.show();
	return a.exec();
}

#include <QtCore>
#include <QtGui>

int main(int argc, char **argv)
{
	QApplication a(argc, argv);
	QGraphicsView gv;
	QGraphicsScene scene(-200,-200,400,400);
	gv.setScene(&scene);
	gv.setRenderHint(QPainter::Antialiasing);
    gv.setDragMode(QGraphicsView::ScrollHandDrag);

	QPushButton btn("My Button");
    QGraphicsProxyWidget *pw = scene.addWidget(&btn);
    pw->setPos(0, 0);
    pw->rotate(-20);
    gv.show();
	return a.exec();
}

To copy to clipboard, switch view to plain text mode 

gives:

Is there a solution to this problem ?

[wysota]

The solution is to use a widget style different than the native WindowsXP/Vista style. You may also browse the bug tracker to see if this bug was reported and fixed between 4.6.0 and 4.6.1. If so, you can download a patch and apply it to your 4.6.0 sources and rebuild the style. You may also downgrade to Qt 4.5.3
