Usually, you can use a separate script file to store the
|
|
implementaion of each new widget class. If you have several of those
|
|
files, it will be a good idea to group the files into a single
|
|
directory and create a <tt>tclIndex</tt> file for them so that the new
|
|
classes can be auto-loaded.
|
|
<P>
|
|
Suppose you have put the class files into the directory <tt>/usr/my/tix/classes</tt>. You can create the <tt>tclIndex</tt> file using
|
|
the <tt>tools/tixindex</tt> program that comes with Tix:
|
|
<P>
|
|
<blockquote> <P><tt> cd /usr/my/tix/classes<BR>
|
|
/usr/my/Tix8.1/tools/tixindex *.tcl
|
|
</tt>
|
|
<P></blockquote>
|
|
The <tt>tclIndex</tt> file must be created by the <tt>tixindex</tt>
|
|
program. You cannot use the standard <tt>auto_mkindex</tt> command
|
|
that comes with Tcl.
|
|
<P>
|
|
Once you have created the <tt>tclIndex</tt> file, you can use your new
|
|
widget classes by auto-loading. Here is a small demo program that
|
|
uses the new TixArrowButton class:
|
|
<P>
|
|
<blockquote> <P><tt> #!/usr/local/bin/tixwish<BR>
|
|
lappend auto_path /usr/my/tix/classes<BR>
|
|
<BR>
|
|
# Now I can use my TixArrowButton class!<BR>
|
|
#<BR>
|
|
tixArrowButton .arr -direction n<BR>
|
|
pack .arr
|
|
</tt>
|
|
<P></blockquote>
