5 GUI Applications

when you add the list box and automatically sets the Callback property to

execute this subfunction whenever the callback is triggered (which happens

when users select an item in the list box).

In this case, there is no need for the list box callback to execute, so you should

delete it from the GUI M-file. It is important to remember to also delete the

Callback property string so MATLAB does not attempt to execute the callback.

You can do this using the property inspector:

See the description of list boxes for more information on how to trigger the list

box callback.

Setting the Background to White

The list box create function enables you to determine the background color of

the list box. The following code shows the create function for the list box that

is tagged

ResultsList.

function ResultsList_CreateFcn(hObject, eventdata, handles)

% Hint: listbox controls usually have a white background, change

% 'usewhitebg' to 0 to use default. See ISPC and COMPUTER.

usewhite/jointfilesconvert/339281/bg = 1;

if usewhite/jointfilesconvert/339281/bg

set(hObject,'BackgroundColor','white');

else

set(hObject,'BackgroundColor',get(0,'defaultUicontrolBackgroundColor'));

end
