Public Shared Function GetForWindowId (windowId As WindowId) As InputActivationListener

Parameters

windowId: WindowId

The window identifier.

Returns

InputActivationListener

A InputActivationListener object for the specified top-level window, or a new InputActivationListener if one doesn't exist.

If windowId is invalid, is owned by a different thread than the calling thread, or is a child window, GetForWindowId returns null.

Remarks

GetForWindowId only supports top-level windows on the same thread as the caller.

Calling GetForWindowId multiple times will return the same object each time.

In all cases there can only be a single InputActivationListener associated with a particular Window ID.
