Containers are created with default layout managers. Most use BorderLayout by default. Panels use FlowLayout by default.
Layout managers do not apply to all containers. For example, ScrollPane,
JScroll Pane, JTabbedPane, JDesktopPane,
and JSplitPane
have
their own special layouts that cannot be changed.
You can change the layout manager of most containers using the component palette, Form window, or Component Inspector.
To set the layout manager using the component palette:
If you are not yet familiar with the icons that represent the various layout managers, move the pointer over each image to see the tool tips.
To set the layout manager using the Form window or Component Inspector:
![]() |
When you change layouts, the IDE remembers the properties of the discarded layout manager. If you change the layout manager back, the component looks the same as it previously looked with that layout manager. The only exception can happen when you switch from AbsoluteLayout to GridBagLayout. In this case, the new properties are created such that GridBagLayout looks as close as possible to the previous AbsoluteLayout. Therefore, any previous GridBagLayout property settings are lost. |
