how to use drawItems() in PyQt?
- by DSblizzard
I have these two code fragments in program:
class TGraphicsView(QGraphicsView):
def __init__(self, parent = None):
print("__init__")
QGraphicsView.__init__(self, parent)
def drawItems(self, Painter, ItemCount, Items, StyleOptions):
print("drawItems")
Brush = QBrush(Qt.red, Qt.SolidPattern)
Painter.setBrush(Brush)
Painter.drawEllipse(0, 0, 100, 100)
...
Mw.gvNavigation = TGraphicsView(Mw) # Mw - main window
Mw.gvNavigation.setGeometry(0, 0, Size1, Size1)
Mw.gvNavigation.setScene(Mw.Scene)
Mw.gvNavigation.setSceneRect(0, 0, Size2, Size2)
Mw.gvNavigation.show()
_init_ works, Mw.gvNavigation is displayed and there are Mw.Scene items in it, but drawItems() isn't called. Please explain, what I'm doing wrong.
