Initialising in a Class

Hello:

I have been experimenting with the Shape control. One of the things that I wanted to do want to have one shape have the same colour as the form's BackColor. This led to define class ... * No procedure or function statement here! BackColor=ThisForm.BackColor but VFP does not like this. Apparently, there is some limitation to the expression being evaluable at compile-time. I had to create an Init to do the initialisation.

Or am I missing something? What are the limitations to the initialisation expression?

Sincerely,

Gene Wirchenko
