The GUI Designer's Palette tool window can contain groups which can be used as a means of organizing GUI components. Each Group can contain one or more GUI components, and can optionally display a custom icon for each component.
Initially, there are 2 default groups: Swing that contains the default
javax.swing components, and Palette that contains one default node: Non-Palette Component. You can create other Groups for components from your libraries of GUI components and forms.
To create a new Group
- Right-click anywhere in the Palette tool window and choose Add Group on the context menu.
- In the Add Group dialog, type a name for the new Group.
- Click OK. A new group with the specified name adds to the Palette.
