.SH SYNOPSIS
|
||
|
|
\fBtk\fR \fIoption \fR?\fIarg arg ...\fR?
|
||
|
|
.BE
|
||
|
|
|

.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
The \fBtk\fR 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 \fIoption\fR argument. The legal forms are:
|
||
|
|
.TP
|
||
|
|
\fBtk appname ?\fInewName\fR?
|
||
|
|
If \fInewName\fR isn't specified, this command returns the name
|
||
|
|
of the application (the name that may be used in \fBsend\fR
|
||
|
|
commands to communicate with the application).
|
||
|
|
If \fInewName\fR is specified, then the name of the application
|
||
|
|
is changed to \fInewName\fR.
|
||
|
|
If the given name is already in use, then a suffix of the form
|
||
|
|
``\fB #2\fR'' or ``\fB #3\fR'' is appended in order to make the name unique.
|
||
|
|
The command's result is the name actually chosen.
|
||
|
|
\fInewName\fR 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 \fBsend\fR command,
|
||
|
|
this command will reenable them and recreate the \fBsend\fR
|
||
|
|
command.
