Parameter

Parameter	Description
component	The component.
panel	The panel.
layout	The grid bag layout.
gridx	The grid x position.
gridwidth	The grid width.
weightx	How much extra horizontal space the component will get.
gridy	The grid y position.
gridheight	The grid height.
weighty	How much extra vertical space the component will get.
fill	Whether the component should expand to fill its space.
anchor	Where to place the component if it doesn't fill its space.
