Populating Your GUI Form
This part explains how to place and lay out components on forms in the GUI Designer.
When you create a new GUI form, a top-level JPanel is automatically placed in the Form Workspace ready to receive the additional components that will make up the GUI you want to build. The pane's Layout Manager property is set to the default layout manager configured in the GUI Designer Options.
The valid target areas where you can place a component, depend on the selected layout.
Undo and Redo work for add, copy, move and delete operations in the GUI Designer.
Use Escape to cancel any placement operation.
