DesktopWindow.Handle

From Xojo Documentation

Read-Only Property (As Ptr )
PtrValue = aDesktopWindow.Handle

New in 2021r3

Supported for all project types and targets.

Returns a handle to the window. Use this instead of the deprecated MacWindowPtr and WinHWND.

Notes

For interfacing with Cocoa APIs using Declares, Window.Handle always gives a NSWindow or NSPanel.
