以下代码应创建QGraphicsView小部件,该小部件拥有一个QGraphicsScene,其中包含文本:

#!/usr/bin/python

import sys
from PyQt4.QtGui import *


if __name__ == '__main__':
  app = QApplication(sys.argv)

  view = QGraphicsView()  
  scene = QGraphicsScene()

  scene.addText("Hello!")

  view.setScene(scene)
  view.show();

  sys.exit(app.exec_())

这将打开窗口,将文本放在那里,但在关闭窗口后 - python转储核心并打印出几个问题:

(python:5387): Gtk-CRITICAL **: IA__gtk_container_add: assertion `GTK_IS_CONTAINER (container)' failed

(python:5387): Gtk-CRITICAL **: IA__gtk_widget_realize: assertion `GTK_WIDGET_ANCHORED (widget) || GTK_IS_INVISIBLE (widget)' failed
