tk

Manipulate Tk internal state

SYNOPSIS

(tk option ?arg arg ...?)

DESCRIPTION

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

(tk 'appname)
(tk 'appname newName)
If newName isn't specified, this procedure returns the name of the application (the name that may be used in send procedures 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 procedure'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 procedure, (with inhibit-send) this procedure will reenable them and recreate the send procedure.
