Pt_ARG_ICON_WINDOW

Hi

I create different types of windows from one base window module.

Is it possible to have different Icons to display in PDM for each window?

I would like to have several Icons created in Phab and then set the
Pt_ARG_ICON_WINDOW resource when the window is created. Is this possible?
How do I set the Pt_ARG_ICON_WINDOW resource to an icon created with Phab
from code?

TIA

Augie
