Hi,, I have a Button, i wanna set the SetRectRgn for that button.
How is that done, I DONT wanna make a new Rgn for and then set the Buttons Rgn to the new Rgn. What I wanna do is obtain a pointer to the region already initialized for the button and modify that rgn, with SetRectRgn!!
Why ?, I don't wanna make a new rgn because it takes memory. Modifying an region that's already initialized is that not an option ?
How is it done ?
