The following code block:
class MDraw(QtWidgets.QGraphicsView): def __init__(self, parent): super(MDraw, self).__init__(parent) self.data = None self.width = 0 self.height = 0 def resizeEvent(self, event): self.width = event.size().width() self.height = event.size().height() self.draw(self.data) def draw(self, indata): self.image = QImage(self.width, self.height, QImage.Format_ARGB32) self.image = QImage(self.width, self.height, QImage.Format_Grayscale8) self.image = QImage(self.width, self.height, QImage.Format_Alpha8) self.image = QImage(self.width, self.height, QImage.Format_RGB32) qpainter = QPainter(self.image) bbush = QBrush(QColor(90,0,0)) qpainter.setBrush(bbush) qpainter.drawRect(20, 20, 80, 80) qpainter.end() self.pixmap = QPixmap.fromImage(self.image) self.pixmapItem = QGraphicsPixmapItem(self.pixmap) scene = QGraphicsScene() scene.addItem(self.pixmapItem) self.setScene(scene)Works fine when expanding the widget size, but produces artifacts when shrinking?
