Method Detail

activate

public void activate()

Description copied from class: AbstractEditPolicy

Called to activate this EditPolicy. When activated, this edit policy may wish to add listeners to its host, its host's model, or some other Object. These listeners should be freed in AbstractEditPolicy.deactivate(). AbstractEditPolicy.initialize() is called to do any setup work that does not need to be undone. There is a current bug that initialize() is called every time activate is called. It will only be called once in the future

Overrides:

activate in class AbstractEditPolicy

Following copied from interface: org.eclipse.gef.EditPolicy

EditPart.activate(), EditPolicy.deactivate(), EditPart.installEditPolicy(Object, EditPolicy)

addSelectionListener

protected void addSelectionListener()

deactivate

public void deactivate()

Description copied from interface: EditPolicy

This policy should shutdown and remove all listeners established in activate(). deactivate() will be called either when the host is deactivated, or when this policy is uninstalled from its host.

Overrides:

deactivate in class AbstractEditPolicy

Following copied from interface: org.eclipse.gef.EditPolicy

See Also:

EditPart.deactivate(), EditPolicy.activate(), EditPart.removeEditPolicy(Object)

getTargetEditPart

public EditPart getTargetEditPart(Request request)

Description copied from interface: EditPolicy

Returns the host EditPart if the EditPolicy works with the given request type, otherwise return null. For all practical uses, this method has "boolean" behavior. It is possible, although rarely useful, to return an EditPart other than the host.

Overrides:

getTargetEditPart in class AbstractEditPolicy

hideFocus

protected void hideFocus()

hideSelection

protected abstract void hideSelection()

removeSelectionListener

protected void removeSelectionListener()

setFocus

protected void setFocus(boolean value)

setSelectedState

protected void setSelectedState(int type)

showFocus

showPrimarySelection

protected void showPrimarySelection()

showSelection
