maybe you can use paintEvent

like:

class PaintWidget(QWidget):

    def paintEvent(self, event):
        painter = QPainter(self)
        painter.setPen(QPen(1, Qt.black))
        painter.fillRect(self.rect(), Qt.yellow)

[upmanager]

I want make mask for yellow area. So, Hope to show only yellow area on widget, and other side want to hide.
