Is it possible to make the different lines of text in a
listbox style UICONTROL different colors?

cdata doesn't seem to do anything and backgroundcolor only
accepts a single 3-matrix RGB value.

As far as I know (and I tried this very hard!), it's not
possible.

Try

h=uicontrol('style',...
'popupmenu',...
'String',...
{'<HTML>Row 1<HTML>',...
'<HTML>Row 2<HTML>'});

Actually, it's pretty easy using HTML:
uicontrol('Style','list', 'String', ...
 {'<HTML>Hello</HTML>', ...
 'world', ...
 '<HTML>!!!</HTML>'} );

This is based on the undocumented fact that all Matlab GUI
components are based on Java Swing, which supports HTML
rendering.

Perfect! I am pleasantly surprised. This will make string
parsing a bit tougher, but it's exactly what I want. Thank
you all.

I tried the same thing for a multi-line text-box, without success ... any other ideas for this?

Thanks!

I believe that if you want a multi-color uicontrol('Style','text')
or uicontrol('Style','edit') then you will need to fiddle at the java
level.

You can use JEditorPane or JTextPane: see
http://java.sun.com/docs/books/tutorial/uiswing/components/text.html
for an explanation, and my UIComponent
(http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=14583)
for a sample integration with Matlab GUI.
