DESCRIPTION
       Tk_WindowId and the other names listed above are all macros that return
       fields from Tk's local data structure for tkwin.	 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 par‐
       ent is the token that was specified when tkwin was created, or NULL for
       main windows.

       Tk_Interp  returns  the Tcl interpreter associated with a tkwin or NULL
       if there is an error.

       Tk_Display returns a pointer to the Xlib display structure  correspond‐
       ing  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 location information
       refers to the upper-left pixel in the window, 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 attributes of the tkwin's window, such
       as background pixmap, event mask, and so on (Tk keeps track of all this
       information  as	it is changed by the application).  Note: it is essen‐
       tial that applications use Tk procedures like  Tk_ResizeWindow  instead
       of X procedures like XResizeWindow, so that Tk can keep its data struc‐
       tures up-to-date.

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

       Tk_IsEmbedded  returns a non-zero value if tkwin 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 is not 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  is
       not 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_Geome‐
       tryRequest for tkwin.

       Tk_MinReqWidth  and  Tk_MinReqHeight  return information about the win‐
       dow'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 vis‐
       ual characteristics of a window.	 Tk_Visual returns the visual type for
       the  window, Tk_Depth returns the number of bits per pixel, and Tk_Col‐
       ormap returns the current colormap for the window.  The visual  charac‐
       teristics  are  normally set from the defaults for the window's screen,
       but they may be overridden by calling Tk_SetWindowVisual.
