|
|
|
|
|
The <B>tk</B> 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 <I>option</I> argument. The legal forms are:
|
|
|
|
|
<P>
|
|
|
|
|
<DL>
|
|
|
|
|
<DT><A NAME="M4">(<B>tk 'appname</B>)</A><DD>
|
|
|
|
|
<DT><A NAME="M5">(<B>tk 'appname </B><I>newName</I>)</A><DD>
|
|
|
|
|
If <I>newName</I> isn't specified, this procedure returns the name
|
|
|
|
|
of the application (the name that may be used in <B><A HREF="./send.n.html">send</A></B>
|
|
|
|
|
procedures to communicate with the application).
|
|
|
|
|
If <I>newName</I> is specified, then the name of the application
|
|
|
|
|
is changed to <I>newName</I>.
|
|
|
|
|
If the given name is already in use, then a suffix of the form
|
|
|
|
|
``<B> #2</B>'' or ``<B> #3</B>'' is appended in order to make the name unique.
|
|
|
|
|
The procedure's result is the name actually chosen.
|
|
|
|
|
<I>newName</I> 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 <B><A HREF="./send.n.html">send</A></B> procedure,
|
|
|
|
|
(with <B>inhibit-send</B>) this procedure will reenable them and
|
|
|
|
|
recreate the <B><A HREF="./send.n.html">send</A></B> procedure.
