PA_GetWindowProcess (wRef) 
long
| Parameter | Type | Description | |
| wRef | PA_WindowRef | | Window reference |
| Function result | long |  | Number of the process that owns the window |
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.
