Advanced Layout
(Optional from here on)
)CardLayout
)GridBagLayout
)Using No Layout Manager
CardLayout (Optional from here on)
) The CardLayout manager arranges
components
in a queue of cards. You can only see one card
at
a time. To construct a CardLayout, simply use
the constructor CardLayout().
) To add a component in the CardLayout
container, use the following method:
void add(Component com,
String name)
CardLayout View Components
)void first(container)
)void last(container)
)void next(container)
)void previous(container)
)void show(Container, String name)
Example 10.10
Testing CardLayout Manager
) Objective: Create two panels in a frame. The
first panel holds named components. The second
panel uses buttons and a choice box to control
which component is shown.
ShowCardLayout
Run
GridBagLayout
The GridBagLayout manager is the most flexible
and the most complex. It is similar to the
GridLayout manager in the sense that both layout
managers arrange components in a grid. The
components can vary in size, however, and can be
added in any order in GridBagLayout.
Example 10.11: Using GridBagLayout Manager
RunShowGridBagLayout
Using No Layout Manager
You can place components in a container without
using any layout manager. In this case, the
component must be placed using the component’s
instance method setBounds().
Example 10.12: Using No Layout Manager
RunShowNoLayout
