Consecutive pastes place each copy to the lower right of the last one.

Duplicating. Select one or more components that you want to duplicate, then do

one of the following:

• Copy and paste the selected components as described above.

• Select

Duplicate from the Edit menu or the pop-up menu. Duplicate places

the copy to the lower right of the original.

• Right-click and drag the component to the desired location. The position of

the cursor when you drop the components determines the parent of all the

selected components. Look for the highlight as described in “Adding a

Component to a Panel or Button Group” on page 6-20.

Front-to-Back Positioning

MATLAB figures maintain separate stacks that control the front-to-back

positioning for different kinds of components:

• User interface controls such as buttons, sliders, and pop-up menus

• Panels, button groups, and axes

• ActiveX controls

You can control the front-to-back positioning of components that overlap only

if those components are in the same stack. For overlapping components that

are in different stacks:

• User interface controls always appear on top of panels, button groups, axes,

and ActiveX controls they overlap.

• Panels, button groups, and axes always appear on top of ActiveX controls.

The Layout Editor provides four operations that enable you to control

front-to-back positioning. All are available from the

Layout menu, which is

shown in the following figure.
