3 Laying Out GUIs and Setting Properties

3-54

Making the Change in the Property Editor. For example, to change the callback name

in a push button’s callback property, select the push button in the Layout

Editor and then select

Property Inspector in the View menu. Scroll down in

the Property Inspector until you come to

Callback, as shown in the following

figure.

As shown, the callback property points to

pushbutton1_Callback in the M-file.

If you need to change the callback property to

Closebutton_Callback, replace

the string

pushbutton1_Callback with Closebutton_Callback in the

Callback field, as shown in the following figure.

Making Sure Your GUI Still Works. If you change the value of any callback

properties manually in the Property Inspector, GUIDE does not update the

corresponding callbacks in the M-file, and might not be able to update the

callback properties or references to the handles structure. If you change the

value of a callback property, you must make sure that

• Callback functions in the M-file are updated.

• Callback function names in the callback properties agree with the names of

the appropriate callback functions in the M-file.
