Layout Manager Properties
Each container component that has a layout manager has layout properties. The list of layout properties depends on the used layout manager.
Select a container component in the Design or Structure view to see its layout properties in the Properties view.
This screenshot shows layout manager properties of a container that has a MigLayout.
When you add a container component to a form, following dialog appears and you can choose the layout manager for the new container. You can also set the layout properties in this dialog.
