Examples: Program GUI C omponents

You can also select a menu item programm atically by setting the pop-up

Value property to the index o f the desired item . For example,

set(pmh,'Value',2)

selects the second item in the pop-up menu with handle pmh.

Use the Index to Determine the Selected String. This exam ple retrieves

the actual string selected in the pop-up menu. It u ses the pop-up menu

Value

property to index into the list of strings. This approach may be useful if your

program dynamically loads the contents of the pop-up menu bas ed on user

action and you need to obtain the selected string. Note that it is necessary to

convert the value returned by the

String property from a cell array to a string.

function popupm enu1 _Callback(hObject,event data)

val = get(hObject,'Value');

string_list = get(hObject,'String');

selected_string = string_list{val}; % Convert from cell array

% to string

% Proceed with callback...

hObject

is the handle of the component for which the event was triggered.

Push Button

This example contains only a push button. Clicking the button closes the GUI.

This is the push button’s Callback callback. It displays the string Goodbye at

the command line and then closes the GUI.

function pushbu tton 1_Callback(hObject,even tdata)

display Good bye
