Thread Subject: How to color a specified line in LISTBOX

I have on my form:
-- 1 Listbox, 2 pushbuttons, 1 edit
=======================================
OBS:

Is this even posible and if yes how exactly somebody modifie my prg or give me some
example prg that do what i want.

Push Button 2 = Load a TXT file
Push Button 1 = Compare EDit/Listbox
=======================================
I want to :

a) Compare what is written in Edit with what a have in LIstbox
         --- this is done NO PRoblem Here.
b) When it match what is in the Edit with the line in LISTbox , -- I want that specific
    line in LIstbox to turn in GREEN === Big Problem
-------------------------------------------------------------------------------------------------------------
Here's a picture with what i want exact:

My Program:

% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB

% varargin command line arguments to Green_Detection (see VARARGIN)

% Choose default command line output for Green_Detection
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes Green_Detection wait for user response (see UIRESUME)
% uiwait(handles.figure1);


% --- Outputs from this function are returned to the command line.

Thanx

simply set your listbox item with HTML colors. for example:
'<html><font color="red">my listbox item</font></html>'

====================================
Thank you for your reply..... but is not exactly what I wanted.

I wanted to color the background of a SPECIFIC line in listbox
look at the links above with image.

NOT the WORD and NOt the entire background of the listbox

You'd need to write a custom Java ListCellRenderer class to achieve this (if you're already at it, this new class can also be used to display icons next to your list labels and do other fancy stuff).

Alternately, you could modify the listbox selection color and simply select the relevant entry/entries.

Try this -
'<html><DIV bgcolor="yellow"><font color="red">my listbox item</font></DIV></html>'

It will produce yellow background color for the specific listbox item.
You can do this when setting 'String' property value for each listbox item.
