Adding and removing fields when using a Mclistbox

Hey guys, it's really awesome you can post questions and actually
receive quality answers. I'm designing a program and I'm using the
Mclistbox megawidget. This creates several columns that are resizable
and include headers. My problem is I need to be able to remove the
different columns (take the columns and the contents out of the
listbox. I also need to be able to add in columns. I want to create an
exact program that outlook uses. There are several fields and you can
add or take them out.

If someone could help me out with this, i.e. show me the code, or
provide an example, I would appreciate it very much.

Look at the commands 'pathname column add' and 'pathname column delete'.
You can use those to add or remove columns.

You might also want to consider adding all the columns up front and just
making some of them invisible.
