Passing some events from Control to 3D view

DavidGasku

I have one situation I don't know how to handle, hope some wise one can help me :)

I have one Control panel, like a pop up. I want to handle BUTTON_LEFT, but pass any other event down to the map, so you can click, but if you MOUSE_WHEEL, the map still zooms. ~~~~

This is what I've tried: 1) gui_input() in popup, only using accept_event when BUTTON_LEFT Problem: unhandled_input in the map is not called, as the event is considered handled. 2) using input in the map instead of unhandled_input. This way works fine with the popup situation Problem: the map is also zoomed when I use the MOUSE_WHEEL in any Control, like in a Slider (even with Mouse Filter set to Stop)

What would be the best way to get the desired behaviour? Thanks in advance

For 2) you could implement an additional state that keeps track of what node the mouse is over then use that state value in an if conditional check to determine whether to zoom on MOUSE_WHEEL or not.

Ok, just to document my solution, in case someone finds the same problem. I tried with signals, but coupling a specific panel with the map didn't seem a good fix. Finally I found an undocumented function, that seems to be implemented as a workaround for a similar issue: https://github.com/godotengine/godot/issues/17326

You can simply use get_viewport().unhandled_input(event) to propagate the event as unhandled to the viewport.

Still, I don't get what is the benefit of marking an event as handled even when not accepted by any panel.

Will try that, but seems like a hack, doesn't it?. Should I report this as a bug? Why does the event change to handled if nobody handles it?

A Hack? Not in particular. But is it the most optimal solution? Perhaps not.

Didn't want to sound as ungrateful, thanks for helping :)
