DESCRIPTION
     Tk_WindowId and the other names listed above are all  macros
     that return fields from Tk's local data structure for tkwin.

Tk Library Procedures                            Tk_WindowId(3TK)



     None of these  macros  requires  any  interaction  with  the
     server;  it is safe to assume that all are fast.

     Tk_WindowId returns the X identifier for tkwin, or  NULL  if
     no X window has been created for tkwin yet.

     Tk_Parent returns Tk's  token  for  the  logical  parent  of
     tkwin.   The  parent  is  the  token that was specified when
     tkwin was created, or NULL for main windows.

     Tk_Display returns a pointer to the Xlib  display  structure
     corresponding  to  tkwin.   Tk_DisplayName  returns an ASCII
     string identifying tkwin's display.  Tk_ScreenNumber returns
     the index of tkwin's screen among all the screens of tkwin's
     display.  Tk_Screen returns a pointer to the Xlib  structure
     corresponding to tkwin's screen.

     Tk_X, Tk_Y, Tk_Width, and Tk_Height return information about
     tkwin's  location within its parent and its size.  The loca-
     tion information refers to the upper-left pixel in the  win-
     dow,  or  its  border if there is one.  The width and height
     information refers to the interior size of the  window,  not
     including  any  border.   Tk_Changes  returns a pointer to a
     structure containing all of the above information plus a few
     other   fields.   Tk_Attributes  returns  a  pointer  to  an
     XSetWindowAttributes structure describing all of the  attri-
     butes  of  the  tkwin's  window,  such as background pixmap,
     event mask, and so on (Tk keeps track of all  this  informa-
     tion  as  it  is  changed  by the application).  Note: it is
     essential  that  applications   use   Tk   procedures   like
     Tk_ResizeWindow  instead of X procedures like XResizeWindow,
     so that Tk can keep its data structures up-to-date.

     Tk_IsContainer returns a non-zero value if tkwin is  a  con-
     tainer,  and  that  some  other application may be embedding
     itself inside tkwin.

     Tk_IsEmbedded returns a non-zero value if tkwin is is not  a
     free-standing  window,  but rather is embedded in some other
     application.

     Tk_IsMapped returns a non-zero value if tkwin is mapped  and
     zero if tkwin isn't mapped.

     Tk_IsTopLevel returns a non-zero value if tkwin  is  a  top-
     level window (its X parent is the root window of the screen)
     and zero if tkwin isn't a top-level window.

     Tk_ReqWidth and Tk_ReqHeight return  information  about  the
     window's  requested  size.   These  values correspond to the
     last call to Tk_GeometryRequest for tkwin.

     Tk_MinReqWidth and Tk_MinReqHeight return information  about
     the   window's   minimum   requested   size.   These  values
     correspond to the last call to Tk_SetMinimumRequestSize  for
     tkwin.

     Tk_InternalBorderLeft,               Tk_InternalBorderRight,
     Tk_InternalBorderTop  and Tk_InternalBorderBottom return the
     width of one side of  the  internal  border  that  has  been
     requested  for  tkwin,  or  0  if  no  internal  border  was
     requested.  The return value is simply the last value passed
     to Tk_SetInternalBorder or Tk_SetInternalBorderEx for tkwin.

     Tk_Visual,  Tk_Depth,  and  Tk_Colormap  return  information
     about  the  visual  characteristics  of a window.  Tk_Visual
     returns the visual type for the window, Tk_Depth returns the
     number  of  bits  per  pixel,  and  Tk_Colormap  returns the
     current colormap for the window.  The visual characteristics
     are  normally set from the defaults for the window's screen,
     but they may be overridden by calling Tk_SetWindowVisual.
