Is there an easy way to find the position of the non justified side of a PANE ?
You can easily query the position for the side that has been justified but not so much for the non justified side that I know of.
If a panel is bottom justified, how do I find the panels top position ?
Keeping mind you could create a pane, bottom justified and on the screen it appears bottom justified, but then you could mirror it and then the panel although bottom justified would appear to be top justified visually
