Customizing Callbacks in GUIDE

warnbeforesave. If possible, change the Tag property before saving the GUI

to cause GUIDE to autom atically create callback templates having names you

prefer. H owever, if you decide to change a

Tag property after saving the G U I,

GUIDE updates the following items according to the new

Tag,providedthat

all components have distinct tags:

• The component’s callback functions in the GUI code file

• The value of the component’s callback properties, which y ou can view in

the Property Inspector

• References in the code file to the field of the

handles structure that

contains the component’s handle. See “handles Structure” on page 8-22 for

more information about the

handles structure.

To rename a particular callback function without changing the

Tag property,

• In the Property Inspector, replace the name string in the callback property

with the new name . For example, if the value of the callback property for

apushbuttonin

mygui is

mygui('pushbutton1_Callback',hObject,ev entdata,guidata(hObject ))

the string pushbutton1_Callback isthenameofthecallbackfunction.

Changethenametothedesiredname,forexample,

closethegui.

• As necessary, update instances of the callback function name in the code

file (for example, to

function closet hegu i in its function definition).

After y ou alter a callback signature, when ever you clic k its pencil-and-paper

icon

to go to the function definition in the GUI code file, GUIDE presents

a dialog box for you to confirm the changes you made.
