I posted this question on utilitybase but was told I would get more luck asking Rigo or ssolie over here.
How do I create a simple rectangle (preferably non-fixed) that I can draw something in in a ReAction window??
I have tried Filler, Frame, FillRect but was told Space was the way to go. With the three former I got nothing, not a single pixel. With Space I atleast get my hook called but as expected its parameters doesn't contain any relevant information, such as the very simple x/x/w/h of my object in the window.
I tried using "render->gpr_GInfo->gi_Gadget->LeftEdge" etc. but that gives me the size of the parent group. Very useful... (not).
Tried "render->gpr_GInfo->gi_Domain.Left" etc. but those apparently hold the size of the window. Come on!

How do I do this and why is it so difficult??
