Scene viewport : Set path from node button press

[LaidlawFX]

Hello,

I am trying to set the path of the current scene viewport via a button press from a hda.

I know these python docs below are the key, but I can't seem to tie the relevant python functions together.

Any help would be great. 

Thanks,

Ok I figured it out a bit based on this chat.

This code was put into the Python Source Editor. If you have a geometry object /obj/geo1 in your scene, it will change the path of the SceneViewer to node. It will do a simple check if it is pinned and pin it. Probably could use a bunch of exceptions...

import hou
node = hou.node('/obj/geo1')
scene_pane = hou.ui.curDesktop().paneTabOfType(hou.paneTabType.SceneViewer)
if scene_pane.isPin() :
    scene_pane.setPin(False)
scene_pane.setPwd(node)
scene_pane.setPin(True)

which needs one of these

Then you can use these.

Hope that helps future me, and other fine folks.
