First thank for your post.
Have you an idea why in XE3 the same with the same code, the fill property do nothing (we can not fill the triangle) ?

I think is better to put the code to assign the Polygon points in a procedure like onresize or something like this. Don’t need to assign on every paint event. This event can occur a lot of times without polygon changes.

Hey Anon,
I would not agree with you. Delphi is "unmanaged", so there is no garbage collector to free up things when they are no longer accessible. It is a typical approach to use constructor and destructor of the class to respectively allocate and release any memory used by a class instance.

Don’t ever finalize fields in the destructor! It’s unsafe and unnecessary.
