Hi all, I'm trying to make a fade effect as explained here:
http://doc.trolltech.com/qq/qq16-fader.html http://labs.trolltech.com/blogs/2007/08/21/fade-effects-a-blast-from-the-past/ I have a main windows and I change the centralwidget on some user action so I do somenthing like: self.setCentralWidget(newwidget) I would like to have a fade effect on widget change so I tryed to do a FaderWidget and call something like: self.setCentralWidget(FaderWidget(newwidget)) this is my not working attempt for FaderWidget: class widgetFader(QWidget): def __init__(self,faded,parent=None): super(widgetFader,self).__init__(parent) faded.setupUi(faded) self.timeline=QTimeLine(3000,self) self.connect(self.timeline, SIGNAL("frameChanged(int)"), SLOT("update()")) self.timeline.setFrameRange(0,100) self.timeline.setCurveShape(QTimeLine.EaseInOutCurve) if faded: self.startBrush=faded.palette().window() else: self.startBrush=Qt.white def startAnimation(self): self.timeline.start() def paintEvent(self,event): painter=QPainter(self) frame=self.timeline.currentFrame() #print frame/100.0 painter.setOpacity(frame/100.0) painter.fillRect(self.rect(),self.startBrush) if frame>=100: self.close() what's wrong? waht is the right way to have a fader widget? thanks Nicola _______________________________________________ PyQt mailing list [email protected] http://www.riverbankcomputing.com/mailman/listinfo/pyqt
