QGraphicsWidget does not respect focusPolicy

Widgets that are added to a QGraphicsScene via QGraphicsProxyWidget do not obey the QWidget's or QGraphicsProxyWidget's focus policy.

For example, having a QCheckBox with Qt::NoFocus policy will take the focus away from a QLineEdit.

This only appears to occur for widgets on canvas.

Non QGraphicsView widgets do obey the focusPolicy as expected.

Update: The fix was reverted before 4.4.1 was released - this task has been reopened. The original fix was wrong.

Test case main.cpp to reproduce issue
======================================
#include <QtGui>

class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow(QWidget *parent = 0)
: QMainWindow(parent)

{ QWidget *w = new QWidget(this); setCentralWidget(w); QVBoxLayout *layout = new QVBoxLayout(w); #if 0 // Non Widget on Canvas approach QCheckBox *cb = new QCheckBox("Check Box"); cb->setFocusPolicy(Qt::NoFocus); layout->addWidget(cb); layout->addWidget(new QLineEdit); #else // Widget on Canvas approach QGraphicsScene *scene = new QGraphicsScene; QGraphicsWidget *gw = new QGraphicsWidget; scene->addItem(gw); QGraphicsLinearLayout *gwLayout = new QGraphicsLinearLayout(Qt::Vertical, gw); QCheckBox *cb = new QCheckBox("Check Box"); cb->setFocusPolicy(Qt::NoFocus); QGraphicsProxyWidget *cbProxyWidget = new QGraphicsProxyWidget; cbProxyWidget->setFocusPolicy(Qt::NoFocus); cbProxyWidget->setWidget(cb); gwLayout->addItem(cbProxyWidget); QGraphicsProxyWidget *leProxyWidget = new QGraphicsProxyWidget; leProxyWidget->setWidget(new QLineEdit); gwLayout->addItem(leProxyWidget); QGraphicsView *view = new QGraphicsView(scene); layout->addWidget(view); #endif }

};

int main(int argc, char **argv)
{
QApplication a(argc, argv);
MainWindow mw;
mw.show();
return a.exec();
}
