Hello and sorry if this question has come up already. Couldn’t find answers myself.
I’ve got one button on the titlebar that I use to set the layer for the window (kinda on top/on bottom switch).
What I’d like to do is change the appearance of the button depending on the layer that the window is set to. But I can’t figure out how to change the button style for a specific window (other than switching the whole decoration).
Is there a way to do this in Fvwm? Thank you for your help.
(I’ll just add these three mock-ups here to clarify what kind of buttons I want to change between)
