Hi all,

I'm upgrading to PB 2021 and the latest version of PFC.  Trying to upgrade some of my application windows, object, etc. to make better use of the PFC.  Does anyone know what the difference is between pfc_w_master and pfc_w_sheet?

Thank you,
~~~Tracy

Hi Tracy;

   If you use the PB IDE's "Object Browser" feature, you will be able to see the dependencies of the PFC Classes, PFE Classes and your PB App Classes and how they inter-relate. However basically, PFC_Master is the Ancestor of PFC_Sheet. You should see all this in the Object Browser. For example:

thank you! I was wondering why all of my main windows seem to be descendants of w_sheet and not w_master. I obviously forgot something I learned 20+ years ago! lol!

pfc_w_master/w_master is the ancestor window for all windows in the PFC. Thus, all the various types of ancestor windows in the PFC (w_frame, w_response, w_child, w_popup, w_sheet, w_main) are all descendants of w_master.
