The last month I was working on a complete rewrite of the FPGUI native AROS interface.
I found out that AROS allows to make windows as a parent to a window (in contrast to AmigaOS) so now every item on the screen is created as a window. This makes it much easier to handle events especially paint with overlapping layers and so on. Its far from perfect but I think thats the better way.
Sadly I found again a drawback there exist functions to show/hide windows in Aros, but they DO NOT work, especially the HideWindow function. Seems its already known in Aros forum long time and still not changed, so I made a workaround and change the size to 0,0 when a item is Hidden, not a nice way but at I have no other idea.
I’m rather satisfied with the result as it is now, so i put it on to the links for download (together with the source of aros fpgui).
