protected GridBagConstraints | 
GridBagLayout.defaultConstraints
This field holds a gridbag constraints instance
 containing the default values, so if a component
 does not have gridbag constraints associated with
 it, then the component will be assigned a
 copy of the  
defaultConstraints. | 
| Modifier and Type | Field and Description | 
|---|---|
protected Hashtable<Component,GridBagConstraints> | 
GridBagLayout.comptable
This hashtable maintains the association between
 a component and its gridbag constraints.

| Modifier and Type | Method and Description | 
|---|---|
GridBagConstraints | 
GridBagLayout.getConstraints(Component comp)
Gets the constraints for the specified component. 
 | 
protected GridBagConstraints | 
GridBagLayout.lookupConstraints(Component comp)

protected void | 
GridBagLayout.adjustForGravity(GridBagConstraints constraints,
                Rectangle r)
