<P>
This provides lots of useful control over a console:
<DL>
<DT> <CODE>tkcon <b>attach</b></CODE> <I>interpreter</I>
<DD> Attaches tkcon to the named interpreter. The name must be that
returned by <CODE>[tk appname]</CODE> or a valid path to a slave
interpreter. It's best to use this via the <CODE>Console->Attach
Console</CODE> menu.
<DT> <CODE>tkcon <b>buffer</b></CODE> ?<I>size</I>?
<DD> Sets or queries the allowed size of the console text widget in lines.
The text widget will automatically delete leading lines once this number
has been exceeded (read: this is the scroll buffer size).
<DT> <CODE>tkcon <b>bgerror</b></CODE> ?<I>msg errorInfo</I>?
<DD> Does bgerror stuff in the tkcon master interpreter.
<DT> <CODE>tkcon <b>close</b></CODE> or <CODE>tkcon <b>destroy</b></CODE>
<DD> Destroys this tkcon widget.
<DT> <CODE>tkcon <b>congets</b></CODE>
<DD> Behaves like the traditional Tcl <code>gets</code>, but instead of
using <code>stdin</code>, it uses the tkcon console window. By default,
tkcon replaces the standard gets with this command. This behavior can be
controlled by altering the <code>::tkcon::OPT(gets)</code> parameter at
startup. This should not be called directly - instead rely on the
overloaded <code>gets</code>, which has support for the optional varName
parameter.
<DT> <CODE>tkcon <b>console</b></CODE> <I>args</I>
<DD> Passes the args to the tkcon text widget (the console).
<DT> <CODE>tkcon <b>error</b></CODE>
<DD> Pops up a dialog that gives the user a full trace of the last error
received in the tkcon console.
<DT> <CODE>tkcon <b>find</b></CODE> <I>string ?-case TCL_BOOLEAN
-regexp TCL_BOOLEAN?</I>
<DD> Highlights all instances of <I>string</I> in the console. If the string
is empty, it clears any previous highlighting.
<DT> <CODE>tkcon <b>font</b></CODE> ?<I>fontname</I>?
<DD> Sets or returns the font used by tkcon text widgets.
<DT> <CODE>tkcon <b>gets</b></CODE>
<DD> Behaves like the traditional Tcl <code>gets</code>, but instead of
needing <code>stdin</code>, it pops a dialog box up for the user. The
overloaded <code>gets</code> has support for the optional varName parameter.
<DT> <CODE>tkcon <b>getcommand</b></CODE>
<DD> A variation of the <CODE><b>congets</b></CODE> method that requires a
full command to be input before returning.
<DT> <CODE>tkcon <b>hide</b></CODE>
<DD> Withdraw the tkcon display from the screen (make sure you have
a way to get it back).
<DT> <CODE>tkcon <b>history</b></CODE> ?<i>-newline</i>?
<DD> Displays the tkcon history in sourceable form. If <i>-newline</i> is
specified, it separates each command by an extra newline.
<DT> <CODE>tkcon <b>iconify</b></CODE>
<DD> Iconifies the tkcon display.
<DT> <CODE>tkcon <b>linelength</b></CODE> ?<i>value</i>?
<DD> Sets or displays the number that specifies the limit of long result lines.
True result is still captured in $_ (and 'puts $_' works).
<DT> <CODE>tkcon <b>load</b></CODE> <I>filename</I>
<DD> Sources named file into the slave interpreter. If no filename is
given, it will attempt to call <CODE>tk_getOpenFile</CODE> to pop up the
file select box.
<DT> <CODE>tkcon <b>main</b></CODE> ?<I>arg arg ...</I>?
<DD> Passes the args to the main tkcon interpreter to be evaluated and
returns the result.
<DT> <CODE>tkcon <b>master</b></CODE> <I>args</I>
<DD> Passes the args to the master interpreter to be evaluated and
returns the result.
<DT> <CODE>tkcon <b>new</b></CODE>
<DD> Creates a new tkcon widget.
<DT> <CODE>tkcon <b>resultfilter</b></CODE> ?<I>command</I>?
<DD> Specify a command to process the results before outputting it to the
console window. The command receives one argument (the result string) and
the string returned is placed in the console.
<DT> <CODE>tkcon <b>save</b></CODE> ?<I>filename</I> ?<I>type</I>??
<DD> Saves the console buffer to the given filename. If no filename is
given, it will attempt to call <CODE>tk_getSaveFile</CODE> to pop up the
file select box. If no type is given, a dialog will ask you to specify
what portion of the text you want to save.
<DT> <CODE>tkcon <b>set</b></CODE> <I>var ?value?</I>
<DD> Queries or sets a master interpreter variable.
<DT> <CODE>tkcon <b>append</b></CODE> <I>var ?value?</I>
<DD> Like set, but uses <CODE>append</CODE> on the variable.
<DT> <CODE>tkcon <b>lappend</b></CODE> <I>var ?value?</I>
<DD> Like set, but uses <CODE>lappend</CODE> on the variable.
<DT> <CODE>tkcon <b>show</b></CODE> or <CODE>tkcon deiconify</CODE>
<DD> Redisplays tkcon on the screen.
<DT> <CODE>tkcon <b>slave</b></CODE> ?<I>slavename ?arg arg ...?</I>?
<DD> If called with no args, it returns the name of all the tkcon
interpreters. Otherwise given an interp name it passes the args
to the named interpreter to be evaluated and returns the result.
If no args are passed, then it returns the <CODE>[tk appname]</CODE>
of that interpreter.
<DT> <CODE>tkcon <b>title</b></CODE> ?<I>title</I>?
<DD> Sets or returns the title for tkcon.
<DT> <CODE>tkcon <b>version</b></CODE>
<DD> Returns of version of tkcon.
