here a question concerning transparency that differs from all the others:
I know how to check if somebody painted directly into "my" SWT window area.
I also know how to find out if "my" SWT window is covered (partly or completely) by an other window - as long as this window is a "normal" one - but if it uses Microsoft's UpdateLayeredWindow(..) or SetWindowLong(..) with GWL_EXSTYLE I don't "see" it, even if its transparency is set to 255!
Is there a way to discover such things within SWT?
