[Qt-interest] QGraphicsItem can not show the cursor

[christopherx]

Hello all:

    I have made a simple program to show the problem:
 

#include <QtGui/QtGui>

int main(int argc, char **argv)
{
     QApplication app(argc, argv);

	QGroupBox *groupBox = *new* QGroupBox("Contact Details");
	QLabel *numberLabel = *new* QLabel("Telephone number");
	QLineEdit *numberEdit = *new* QLineEdit;

	QFormLayout *layout = *new* QFormLayout;
	layout->addRow(numberLabel, numberEdit);
	groupBox->setLayout(layout);

     QGraphicsScene scene;
     QGraphicsProxyWidget *proxy = scene.addWidget(groupBox);
	///numberEdit->setFocus();/

     QGraphicsView view(&scene);
     view.show();

     *return* app.exec();
}

   I like to see the cursor in numberEdit field when the form is first 
show. 

   With the setFocus() call, I only got keyboard focus.  Is this a 
limitation of  QGraphicsProxyWidget ?
or I missed anything ?

Thanks,
Chris Xu
