Hi all,
I am trying to get my head around EasyPtr (again).
I have been playing with the new ability to create resizable windows.
This
turns out to be not terribly difficult, and I was able to create a
resizable version of the calculator from Norman Dunbar's tutorial without
suffering too much.
However, creating a freely resizable version of QBase is dependent on
being
able to read the size of the newly resized window.and its components. I
have been unable to find any obvious way to do this.
Does anyone know how this is accomplished?
I use the following routine after every move or resize.
It has the advantage of returning the actual values, because calculated
values given to MDRAW for a new position or size can be adjusted by WMAN2.
That may make X even and will always keep the window inside the screen,
including shadow spaces.
