Next try with MDI child
Hello AGraham and Klaus,
first thank you, Klaus (Danke!!) for the helpfull hint about the Black/White Image, but for the things I want to do the solution with the panel and the Image is a dead end. (an Image has no transparent property !!)
In former times i wrote Graphic-Programs in GFA-Basic for Atari there it was easy to draw by multiply the background with the pen and if the position of the pen was changed multiply again and the Image wasn't damaged by the previous position.
Now it seems that it is necessary to have layers, to prevent a damage for the Image. So I tried to add the AutoScroll property to an MDI child, to use the back- and forelayer of the form.
I tried : frm1obj.Value = FormEx2.ControlRef (frm1obj as Door object)
frm1obj.SetProperty("AutoScroll", True)
and frm1obj.FromControl("Form2")
frm1obj.SetProperty("AutoScroll", True)
at different positions in the source before running the parent-form and after but scrollbars apears at the MDI child.
Is there a way to have AutoScroll property for the -child ????
Best regards
Bernd Gödecke
