NAME
     DtWsm.h - workspace manager definitions

SYNOPSIS
     #include <Dt/Wsm.h>

DESCRIPTION
     The <Dt/Wsm.h> header defines structures and function proto-
     types for workspace management services.

     The DtWsmWorkspaceInfo structure contains at least the  fol-
     lowing members:
     Atom            workspace        X atom name for the workspace
     unsigned long   bg               Backdrop background pixel
     unsigned long   fg               Backdrop foreground pixel
     Atom            backdropName     X atom name for backdrop
     int             colorSetId       Number of color set used
     char            *pchTitle        Title of workspace
     Window          backdropWindow   The backdrop window for the
                                      current workspace

     The DtWsmCBContext structure is opaque.   Workspace  manage-
     ment functions that add callbacks to uniquely identify call-
     back functions for later removal, return the  DtWsmCBContext
     structure.

     The header defines the following DtWsmWsReason constants:

          DtWSM_REASON_ADD
          DtWSM_REASON_DELETE
          DtWSM_REASON_BACKDROP
          DtWSM_REASON_TITLE
          DtWSM_REASON_CURRENT

     The header defines the following functions:

     DtWsmCBContext
     DtWsmAddCurrentWorkspaceCallback(Widget widget,
                                      DtWsmWsChangeProc ws_change,
                                      Pointer client_data);

     void DtWsmAddWorkspaceFunctions(Display *display,
                                     Window window);

     void DtWsmRemoveWorkspaceFunctions(Display *display,
                                        Window window);

     DtWsmCBContext
     DtWsmAddWorkspaceModifiedCallback(Widget widget,
                                       DtWsmWsModifiedProc ws_change,
                                       Pointer client_data);

     void DtWsmRemoveWorkspaceCallback(DtWsmCBContext context);

     void DtWsmFreeWorkspaceInfo(DtWsmWorkspaceInfo *pWsInfo);

     Status DtWsmGetCurrentBackdropWindows(Display *display,
                                          Window root);

     Status DtWsmGetCurrentWorkspace(Display *display,
                                     Window root,
                                     Atom *paWorkspace);

     Status DtWsmSetCurrentWorkspace(Widget widget,
                                     Atom aWorkspace);

     Status DtWsmGetWorkspaceInfo(Display *display,
                                  Window root,
                                  Atom aWorkspace,
                                  DtWsmWorkspaceInfo **ppWsInfo);

     Status DtWsmGetWorkspaceList(Display *display,
                                  Window root,
                                  Atom **ppaWorkspaces,
                                  int *pNumWs);

     Status DtWsmGetWorkspacesOccupied(Display *display,
                                       Window window,
                                       Atom **ppaWorkspace,
                                       int *pNumWs);

     void DtWsmSetWorkspacesOccupied(Display *display,
                                     Window window,
                                     Atom *paWorkspaces,
                                     int numWs);

     void DtWsmOccupyAllWorkspaces(Display *display,
                                   Window window);
