problem; I really only want to display/update this single graphic. How would I go about eliminating the flashing? I've read a bit about eliminating flashing in custom widgets with double buffering, but this is a stock Qt widget and I was surprised that updating its pixmap was so visually jarring.
def slotUpdateImage(self): x, y = self.masterImage.width(), self.masterImage.height() if not hasattr(self, 'currentImage'): self.scaledImage = self.masterImage.scale(x * (float(self.controlframe.height()) / y), self.controlframe.height()) self.currentImage = QPixmap() elif self.controlframe.height() != self.oldHeight: self.scaledImage = self.masterImage.scale(x * (float(self.controlframe.height()) / y), self.controlframe.height()) self.oldHeight = self.controlframe.height()
self.currentImage.convertFromImage(self.scaledImage) self.skellabel.setPixmap(self.currentImage)
There's probally a better way, but I've found an easy way is to try and use something like...
def slotUpdateImage(self):
self.currentImage.hide()
(change image)
self.currentImage.show()if you're using sizers, you might have to swap out image with a transparent image so things don't jump around.
def slotUpdateImage(self):
self.currentImage.hide()
self.transImage.show()
(change image)
self.currentImage.show()
self.transImage.hide()anyhow, might be something simple to try.
