It is possible to add controls on top of TImageEnView. Can you please explain why this is possible? I like the option to drag and drop controls around on TImageEnView. Is there a demo available how to drag and drop controls around on TImageEnView?
There is not a way to do this, but many years ago I tried some code that allowed controls to be moved and sized on a control in the same way as in the VCL. You might try searching for that.
TImageEnView is just a TWinControl, so the same code should work fine.
