Make TAdvGroupBox sizable

TAdvGroupBox has an AutoSize property with these sub-properties: gasBoth, gasHorizontal, gasNone, gasVertical.

Similarly, there should be a Sizable property which of course is active only when AutoSize = gasNone.
The sub-properties of Sizable should be: gsBoth, gsHorizontal, gsNone, gsVertical.
For example: When Sizable = gsVertical, then the AdvGroupBox can be sized vertically at run-time with the mouse.

This would be very useful, e.g. when one of the controls inside the AdvGroupBox has the Align property set to alClient!

Implemented

After having installed TMSVCLUIPack 10.7.9.1 today in Delphi 11.1 Alexandria, I have loaded the demo \TMS VCL UI Pack\Demos\AdvGroupBox in Delphi 11.1 Alexandria:

However, TAdvGroupBox still does not have a Sizable property! So is it still not implemented?

I reported on July 17, 2022 this was implemented.
v10.7.9.1 was released on July 5, 2022, hence it doesn't include something implemented on July 5, 2022.
This will be included in v10.8 to be released later this week.

Sorry, I am not very good at detective work. :blush:
