Description
The routine
PA_GetWindowProcess
returns the process number that runs the window whose
reference is passed in
wRef
. If the
wRef
is incorrect, does not exist or refers to a window that does not belong to any process, the routine returns 0 (zero).
If a 4D plug-in is coded to browse all the windows of a 4D working session,
PA_GetWindowProcess
can be used to determine which windows belong to which processes.
To retrieve the process that owns the front window, including floating windows, use
PA_GetFrontWindowProcess
.
