NAME

       Tk_MainWindow, Tk_GetNumMainWindows - functions for querying main window information

SYNOPSIS

       #include <tk.h>

       Tk_Window
       Tk_MainWindow(interp)

       int
       Tk_GetNumMainWindows()

ARGUMENTS

       Tcl_Interp   *interp	(in/out)  Interpreter associated with the application.
_________________________________________________________________

DESCRIPTION

       A main window is a special kind of toplevel window used as the outermost window in an application.

       If interp is associated with a Tk application then Tk_MainWindow returns the application's main window. If there is no Tk application asso-
       ciated with interp then Tk_MainWindow returns NULL and leaves an error message in interp->result.

       Tk_GetNumMainWindows returns a count of the number of main windows currently open in the process.

KEYWORDS

DESCRIPTION

       Each  window  managed  by  Tk  has two names, a short name that identifies a window among children of the same parent, and a path name that
       identifies the window uniquely among all the windows belonging to the same main window.	The path name is used more often in  Tk  than  the
       short name;  many commands, like bind, expect path names as arguments.

       The  Tk_Name macro returns a window's short name, which is the same as the name argument passed to Tk_CreateWindow when the window was cre-
       ated.  The value is returned as a Tk_Uid, which may be used just like a string pointer but also has the properties of a	unique	identifier
       (see the manual entry for Tk_GetUid for details).

       The  Tk_PathName  macro	returns  a  hierarchical  name for tkwin.  Path names have a structure similar to file names in Unix but with dots
       between elements instead of slashes:  the main window for an application has the path name ``.'';  its children have names like ``.a''  and
       ``.b'';	their  children have names like ``.a.aa'' and ``.b.bb''; and so on.  A window is considered to be be a child of another window for
       naming purposes if the second window was named as the first window's parent when the first window was created.  This is not always the same
       as the X window hierarchy.  For example, a pop-up is created as a child of the root window, but its logical parent will usually be a window
       within the application.

       The procedure Tk_NameToWindow returns the token for a window given its path name (the pathName argument) and another  window  belonging	to
       the  same  main	window	(tkwin).  It normally returns a token for the named window, but if no such window exists Tk_NameToWindow leaves an
       error message in interp->result and returns NULL.  The tkwin argument to Tk_NameToWindow is needed  because  path  names  are  only  unique
       within  a  single  application  hierarchy.  If, for example, a single process has opened two main windows, each will have a separate naming
       hierarchy and the same path name might appear in each of the hierarchies.  Normally tkwin is the main window of the desired hierarchy,  but
       this need not be the case:  any window in the desired hierarchy may be used.
