When I write to a PtMultiText widget that is in the background (using
PtWidgetToBack for example), the widget that is in the foreground (using
PtWidgetToFront) flickers momentarily. Any way to get around this?
Thanks.
I think that you are saying that you update a widget hidden
behind another widget, the foreground widget flickers.
A possible solution is to PtUnrealizeWidget() the background
widget. Of course you will need to PtRealizeWidget() the
widget when you want it to appear.
The reason for the flash is that the widget code is using a
simple painters algorithm to update the screen. At the show
I was told that Photon 2.0 either has or would have better
algorithms, but I don’t know if they are implemented yet.
