Hello all, I get some strange TypeErrors when I use the QGraphicsItemAnimation.
An example can be boiled down to the example below taken from the Qt documentation : http://doc.trolltech.com/4.5/qgraphicsitemanimation.html What I get is this error, when the application is running. "TypeError: native Qt signal is not callable" I have installed the snapshot : PyQt-x11-gpl-4.5-snapshot-20090403.tar.gz under python2.6 ( verified the error under python2.5 too ) I can hardly see that I do something wrong.. or is it my installation that has failed?? best Regards BBZ # --------------------------- 8< -------------------------- import sys from PyQt4.QtGui import QApplication , QGraphicsEllipseItem , QGraphicsItemAnimation from PyQt4.QtGui import QGraphicsScene , QGraphicsView from PyQt4.QtCore import SIGNAL , QPointF , QTimeLine app = QApplication( sys.argv ) # create a graphicsview with a moving ball... ball = QGraphicsEllipseItem(0, 0, 20, 20) timer = QTimeLine(5000) timer.setFrameRange(0, 100) animation = QGraphicsItemAnimation() animation.setItem(ball) animation.setTimeLine(timer) for i in xrange( 200 ) : animation.setPosAt(i / 200.0, QPointF(i, i)) scene = QGraphicsScene() scene.setSceneRect(0, 0, 250, 250) scene.addItem(ball) view = QGraphicsView(scene) view.show() timer.start() app.exec_() # --------------------------- 8< --------------------------
