QInputDialog in QGraphicsScene is opened on each mousePressEvent

[Davy]

Good Morning,

I have a QGraphicsScene with two kinds of items : rectangle items and text Items
I use a QInputDialog window to get the user's text and insert it in the text items. However, once the QInputDialog is closed, it opens again whenever I click on the scene. Normally the dialog should open only when I click on the text items but not when I click on rectangle items.
I have this behaviour under Windows but not under Linux.
Here is the code :

    def __init__(self,  parent=None):
        super(TextItem, self).__init__(parent)
        self.text_rect = QRectF(10, 10, 100, 20)
        self.name = ""
        self.brush =  QtGui.QBrush(QtCore.Qt.darkBlue)
 
    def boundingRect(self):
        return self.text_rect

        painter.drawText(self.text_rect,  QtCore.Qt.AlignHCenter| QtCore.Qt.AlignTop, self.name);
        painter.drawRect(self.text_rect)
 
    def setName(self, new_name):
        self.name = new_name
        self.update()
 
 
 
    def mousePressEvent(self, mouseEvent):

            item = RectItem(10 + i*10, 50)
            self.addItem(item)

    app = QApplication(sys.argv)
    size = 200
 
    scene = Scene()
    scene.setSceneRect(QRectF(0, 0, size, size))
    view = QGraphicsView(scene)
    view.show();
 
    sys.exit(app.exec_())

To copy to clipboard, switch view to plain text mode 

Thanks in advance for any help.
