Method Detail

getCloneCommand

protected org.eclipse.gef.commands.Command getCloneCommand(org.eclipse.gef.requests.ChangeBoundsRequest request)
Overrides getCloneCommand() to generate the proper constraint for each child being cloned. Once the constraint is calculated, createCloneCommand(EditPart,Object) is called. Subclasses must implement this method. The logic of this method is taken from ConstrainedLayoutEditPolicy.getAddCommand(Request).

Overrides:
getCloneCommand in class org.eclipse.gef.editpolicies.LayoutEditPolicy
See Also:
org.eclipse.gef.editpolicies.LayoutEditPolicy#getCloneCommand(Request)

createCloneCommand

protected org.eclipse.gef.commands.Command createCloneCommand(org.eclipse.gef.EditPart child,
                                                              Object constraint)

createChangeConstraintCommand

protected org.eclipse.gef.commands.Command createChangeConstraintCommand(org.eclipse.gef.EditPart child,
                                                                         Object constraint)
Overrides:
createChangeConstraintCommand in class org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy

getConstraintFor

protected Object getConstraintFor(org.eclipse.draw2d.geometry.Point point)
Specified by:
getConstraintFor in class org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy

getConstraintFor

protected Object getConstraintFor(org.eclipse.draw2d.geometry.Rectangle rect)
Specified by:
getConstraintFor in class org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy

createChildEditPolicy

protected org.eclipse.gef.EditPolicy createChildEditPolicy(org.eclipse.gef.EditPart child)
Overrides:
createChildEditPolicy in class org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy
