The thing is that the picture attached is not the button created by myself
I want to create the same button using MY code. The problem is drawing that rouned rectangle around the button. I don't need to work with any mouse interface for now, but I want to create a button that has a 3D border around that. If I create a rectangular button, there is an API called "DrawEdge" that I can use to draw 3D borders but it only works for rectangular buttons. If I have circular, triangular, or rounded button, how would I draw a 3D border? I need to draw some kind of lines of rectangles manually using white colour of the left and top sides edges of the button, and drawing the same kind of lines using gray or black colour on the bottom and right sides of the button. Hopefully, you get the problem now
