A GUI to Set Simulink

Model Parameters (GUIDE)

function CloseB utto n_Callback(hObject, eventdata, handles)

% Close the GUI and any plot window that is open

if isfield(h andl es,'PlotFigure') && ...

ishandle(handles.PlotFigure),

close(handles.PlotFigure);

end

close(handles.F14ControllerEditor);

TheListBoxCallbackandCreateFunction

This GUI does not use the list box callback because the a ctions performed on

list box items are carried out by push buttons (Simulate and store results,

Remove,andPlot). GUIDE autom atically inserts a callback stub w hen yo u

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 th e list box).

In this example, there is no need for the list box callback to execute. You

candeleteitfromtheGUIcodefileandatthesametimealsodeletethe

Callback property string in the Property Inspector so that the software does

not attempt to execute the callback.

For more information on how to trigger the list box callback, see the

description of list box.
