elseif button_state == get(hObject,'Min')

% Toggle button is not pressed-take appropriate action

...

end

Note Use a button group to manage exclusive selection behavior for toggle

buttons. You must include the code to control these toggle buttons in the

button group’s

SelectionChangeFcn callback function, not in the individual

toggle button

Callback functions. A button group overwrites the Callback

properties of radio buttons and toggle buttons that it manages. See “Button

Group” on page 8-26 for more information.

Radio Button

You can determine the current state of a radio button from within its callback

by querying the state of its

Value property, as illustrated in the following

example:

if (get(hObject,'Value') == get(hObject,'Max'))

% Radio button is selected-take approriate action

else

% Radio button is not selected-take approriate action

end

Note Use a button group to manage exclusive selection behavior for radio

buttons. You must include the code to control these radio buttons in the

button group’s

SelectionChangeFcn callback function, not in the individual

radio button

Callback functions. A button group overwrites the Callback

properties of radio buttons and toggle buttons that it manages. See “Button

Group” on page 8-26 for more information.

Check Box

You can determine the current state of a check box from within its callback by

querying the state of its

Value property, as illustrated in the following

example:

1 2 ... 188 189 190 191 192 193 194 195 196 197 198 ... 329 330
