Monitoring Workspace Changes

You can monitor workspace changes by using either or both of the following functions:

DtWsmAddCurrentWorkspaceCallback registers an application callback to be called whenever the Workspace Manager is switched to a new workspace. See the DtWsmAddCurrentWorkspaceCallback(3) man page for more information.

DtWsmWorkspaceModifiedCallback registers an application callback to be called whenever a workspace is added, deleted, or changed. See the DtWsmWorkspaceModifiedCallback(3) man page for more information.

To Monitor Workspace Switching

1. Use DtWsmAddCurrentWorkspaceCallback.

In the demo program wsinfo.c, this function is called after the top-level widget is realized.

DtWsmAddCurrentWorkspaceCallback (toplevel, wschangecb, NULL);

where

• toplevel is the application's top level widget.

• wschangecb is the name of the function to be called.

• NULL is the parameter for client data to be passed to the callback. In this case, no data is passed.

To Monitor Other Workspace Changes

1. Use DtWsmWorkspaceModifiedCallback.

   DtWsmWorkspaceModifiedCallback (toplevel, wschangecb, NULL);

   where:

   • toplevel is the application's top-level widget.

   • wschangecb is the name of the function to be called.

   • NULL is the parameter for client data to be passed to the callback. In this case, no data is passed.
