Method Detail

createDragSourceFeedbackFigure

protected IFigure createDragSourceFeedbackFigure()

createSelectionHandles

protected List createSelectionHandles()

Overrides:

createSelectionHandles in class SelectionHandlesEditPolicy

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 SelectionEditPolicy

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

See Also:

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

eraseChangeBoundsFeedback

protected void eraseChangeBoundsFeedback(ChangeBoundsRequest request)

Erase feedback indicating that the receiver object is being dragged. This method is called when a drag is completed or cancelled on the receiver object.

Parameters:

dragTracker - org.eclipse.gef.tools.DragTracker The drag tracker of the tool performing the drag.

eraseSourceFeedback

public void eraseSourceFeedback(Request request)

Erase feedback indicating that the receiver object is being dragged. This method is called when a drag is completed or cancelled on the receiver object.

Overrides:

eraseSourceFeedback in class AbstractEditPolicy

Parameters:

dragTracker - org.eclipse.gef.tools.DragTracker The drag tracker of the tool performing the drag.

getCommand

public Command getCommand(Request request)

Description copied from interface: EditPolicy

Returns the command for a given request, or null if the EditPolicy does not work with that request type. null is treated as a no-op by the caller, or a zero contribution. The EditPolicy must return an UnexectuableCommand if it wishes to prevent the operation from being performed.

Overrides:

getCommand in class AbstractEditPolicy

getDragSourceFeedbackFigure

protected IFigure getDragSourceFeedbackFigure()

Return the Figure to be used to paint the drag source feedback.

getAlignCommand

protected Command getAlignCommand(AlignmentRequest request)

getMoveCommand

protected Command getMoveCommand(ChangeBoundsRequest request)

getOrphanCommand

protected Command getOrphanCommand(Request req)

hideFocus

protected void hideFocus()

Overrides:

hideFocus in class SelectionEditPolicy

showChangeBoundsFeedback

protected void showChangeBoundsFeedback(ChangeBoundsRequest request)

Display feedback to indicate that the receiver object is being dragged. The default feedback is a rectangle the same size as the figure.

Parameters:

dragTracker - org.eclipse.gef.tools.DragTracker The drag tracker of the tool performing the drag.

showFocus

protected void showFocus()

Overrides:

showFocus in class SelectionEditPolicy

showSourceFeedback

public void showSourceFeedback(Request request)

Description copied from interface: EditPolicy

Shows or updates source feedback if the receiver works with the request type. This method may be called repeatedly for the purpose of updating feedback based on changes to the request object. Does nothing if the EditPolicy does not recognize the given request.

Overrides:

showSourceFeedback in class AbstractEditPolicy

understandsRequest

public boolean understandsRequest(Request request)

Overrides:

understandsRequest in class AbstractEditPolicy
