daphne - how would you like to use the if statement because it isn't clear to me how. Also, rather than creating a string for your callback, just define another function...though depending upon your version of MATLAB you may need to put your above code within a function (rather than a script) so that you can define the callback function too. For example, the following code would be saved to a file named myUrlDownloadExample.m
function myUrlDownloadExample
close all;
% Create a blank figure window
f=figure('Name','Browser GUI demo');
% Add the browser object on the right
jObject = com.mathworks.mlwidgets.html.HTMLBrowserPanel;
[browser,container] = javacomponent(jObject, [], f);
set(container, 'Units','norm', 'Pos',[0.3,0.05,0.65,0.9]);
% Add the URLs listbox on the left
urls = {'http://www.google.ca/'};
hListbox = uicontrol('style','listbox', 'string',urls, ...
'units','norm', 'pos',[0.05,0.05,0.2,0.9], ...
'userdata',browser);
% Set the listbox's callback to update the browser contents
set(hListbox,'Callback',@listBoxCallback);
function listBoxCallback(hObject, eventdata)
strs = get(hObject,'string');
url = strs{get(hObject,'value')};
% browser = get(hObject,'userdata');
msg=['<html><h2>Loading ' url ' - please wait'];
browser.setHtmlText(msg);
pause(0.1);
drawnow;
browser.setCurrentLocation(url);
end
end
