See the "viewport display attributes". I guess you're looking for this one:

"gl_lit: If this detail attribute is 0, the geometry always appears without lighting. This is currently ignored for guide geometry"


So simply create a detail attribute 'gl_lit' and set it to 0 to get a flat look.

See "paneTabUnderCursor()"

https://www.sidefx.com/docs/houdini/hom/hou/Desktop.html [www.sidefx.com]

That's usefull if you trigger a script from within the paneTab you're after. Or you run some polling routine that keeps track which paneTab/type had the last focus.

Alternatively you can get the size of the paneTab and assume the largest one is the main one.

Check the docs for 'opengl tags", you can use them to set prims to render as "unlit"
