how to detect full visibility or partial visibility of a win

Two photon applications: ( Process A and Process B ) have their own
windows:

Process A ------ Window A
Process B ------ Window B

How can I know visibility of window A in Process A whether
it is partially or completely hidden by window B ( of course,
window A is Focus Lost )?

Regards

Hello WeiBing

Check out the funct PhQueryWindowVisible in the docs. It should help you do what you want to do.

Thanks

Also you might want to check out PhQueryRids() (using the Ph_WND_MGR_REGION type) to determine
all of the windows present, and PhRegionQuery() to retrieve their corresponding rectangles.
