Any chance to zoom in/zoom out node graph?

[vtushevskiy]

Would it be possible to implement zoom in/out for whole node graph in the editor?

I have hacked up a quick proof of concept using a suggestion noted here: ocornut/imgui#772 (comment) . It seems to work for both visual and input parts. I can work on it after I land mini-map changes.

Very cool @smilediver !

I don't want to have ImNodes depend on a modified ImGui version. But if there is some community-supported way of doing this, then that would be great to have documented in the repository.

It doesn't require modifications to ImGui. Basically it does two things: goes through ImNodes' draw lists and transforms the vertices; and modifies ImGui's mouse states (like ImGuiIO::MousePos) to be in the zoomed coordinate space. I just hope that ImGui doesn't have some hidden mouse states that we can't control.

hi @smilediver, is a (possibly beta) version of your change available anywhere ? - thanks

[smilediver]

I think it's mostly done. I'll try to find some free time to work on it on Friday to clean it up and review, and maybe will do a PR.

did this ever get implemented?

Hello,
Is this zoom in/out implemented? If yes, how to use it?
Thanks

[navyenzo]

Yes, any news on whether this was implemented?

the mini-map is ok, but wheel-zooming and mouse panning would be awesome

mouse panning would be awesome

Although this feature isn't implemented in the library, I was able to get this to work using EditorContextGetPanning and EditorContextResetPanning
