Token for window.
    
    

    

  










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 parent 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
    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 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 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 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_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.
