NAME    [Toc]    [Back]

     tk	- Manipulate Tk	internal state

SYNOPSIS    [Toc]    [Back]

     tk	option ?arg arg	...?

DESCRIPTION    [Toc]    [Back]

     The tk command provides access to miscellaneous elements of Tk's internal
     state.  Most of the information manipulated by this command pertains to
     the application as	a whole, or to a screen	or display, rather than	to a
     particular	window.	 The command can take any of a number of different
     forms depending on	the option argument.  The legal	forms are:

     tk	appname	?newName?
	  If newName isn't specified, this command returns the name of the    |
	  application (the name	that may be used in send commands to	      |
	  communicate with the application).  If newName is specified, then   |
	  the name of the application is changed to newName.  If the given    |
	  name is already in use, then a suffix	of the form `` #2'' or `` #3''|
	  is appended in order to make the name	unique.	 The command's result |
	  is the name actually chosen.	newName	should not start with a	      |
	  capital letter.  This	will interfere with option processing, since  |
	  names	starting with capitals are assumed to be classes;  as a	      |
	  result, Tk may not be	able to	find some options for the application.|
	  If sends have	been disabled by deleting the send command, this      |
	  command will reenable	them and recreate the send command.
