(solved) Mousewheel over GUI

[Radiant]

How do I detect the mousewheel being used over a GUI? The normal method (on_mouse_click) doesn't register on GUIs, and the variant (on_event eEventGUIMouseDown) doesn't seem to offer a way to detect which way the mousewheel is turned.

I tested this and I was able to use on_mouse_click, the GUI has to be clickable though.

It looks like since mouse.IsButtonDown only works with eMouseLeft, Middle and Right, turning the mouse wheel does trigger on_mouse_click and not on_event over GUIs; I'm guessing because otherwise there actually wouldn't be a way to catch scrolling over a GUI.

And that fixed it, thanks.
