6 Laying Out a GUI

6-18

Adding Components to the Layout Area

This topic tells you how to place components in the layout area and give each

component a unique identifier.

1 Place a component in the layout area. Use either of these ways:

- Click the component in the component palette, then drag it into the layout

area and drop it.

- Select the component in the component palette. The cursor changes to a

cross. Add the component to the layout by either (1) placing the cursor in

the layout area where you want the upper-left corner of the component to

be and clicking, or (2) placing the cursor in the layout area where you want

Button Group Button groups are like panels but can be used to manage

exclusive selection behavior for radio buttons and toggle

buttons.

For radio buttons and toggle buttons that are managed by

a button group, you must include the code to control them

in the button group’s

SelectionChangeFcn callback

function, not in the individual user interface control

(uicontrol)

Callback functions. A button group overwrites

the

Callback properties of radio buttons and toggle

buttons that it manages.

ActiveX

Component

ActiveX components enable you to display ActiveX

controls in your GUI. They are available only on the

Microsoft Windows platform.

An ActiveX control can be the child only of a figure, i.e., of

the GUI itself. It cannot be the child of a panel or button

group.

See “ActiveX Control” on page 8-31in this document for an

example. See MATLAB COM Client Support in the online

MATLAB documentation to learn more about ActiveX

controls.
