I have searched but not found (almost always no hits). I wish to alter/set the pen width when drawing.
I cannot find how to set the pen to XOR so that a second drawing of the same line removes it (for rubber banding).
Any pointers please?
Thank you klaus for those pointers, I don't know why my search didn't find them.
A question now occurs to me. I have never come across ForeLayer in any other language, is there only one? If so does that mean a form has two layers and can they just be switched between etc?
What is its main purpose (why was it invented )
Any further info and common usage would be appreciated.
