Constructor Detail

RulerEditPart

public RulerEditPart(java.lang.Object model)

Method Detail

activate

public void activate()

Description copied from class: AbstractGraphicalEditPart

Extends AbstractEditPart.activate() to also activate all source ConnectionEditParts.

Specified by:

activate in interface EditPart

Overrides:

activate in class AbstractGraphicalEditPart

See Also:

EditPart.activate()

createEditPolicies

protected void createEditPolicies()

Description copied from class: AbstractEditPart

Creates the initial EditPolicies and/or reserves slots for dynamic ones. Should be implemented to install the inital EditPolicies based on the model's initial state. null can be used to reserve a "slot", should there be some desire to guarantee the ordering of EditPolcies.

Specified by:

createEditPolicies in class AbstractEditPart

See Also:

EditPart.installEditPolicy(Object, EditPolicy)

createFigure

protected org.eclipse.draw2d.IFigure createFigure()

Description copied from class: AbstractGraphicalEditPart

Creates the Figure to be used as this part's visuals. This is called from AbstractGraphicalEditPart.getFigure() if the figure has not been created.

Specified by:

createFigure in class AbstractGraphicalEditPart

Returns:

a Figure

deactivate

public void deactivate()

Description copied from class: AbstractGraphicalEditPart

Extends AbstractEditPart.deactivate() to also deactivate the source ConnectionEditParts. Subclasses should extend this method to remove any listeners added in AbstractGraphicalEditPart.activate().

Specified by:

deactivate in interface EditPart

Overrides:

deactivate in class AbstractGraphicalEditPart

See Also:

EditPart.deactivate()

getAccessibleEditPart

protected AccessibleEditPart getAccessibleEditPart()

Description copied from class: AbstractEditPart

Returns the AccessibleEditPart adapter for this EditPart. The same adapter instance must be used throughout the editpart's existance. Each adapter has a unique ID which is registered during AbstractEditPart.register(). Accessibility clients can only refer to this editpart via that ID.

Overrides:

getAccessibleEditPart in class AbstractEditPart

Returns:

null or an AccessibleEditPart adapter

getDiagramViewer

protected GraphicalViewer getDiagramViewer()

Returns the GraphicalViewer associated with the diagram.

Returns:

graphical viewer associated with the diagram.

getDragTracker

public DragTracker getDragTracker(Request request)

Description copied from class: AbstractGraphicalEditPart

Overridden to return a default DragTracker for GraphicalEditParts.

Specified by:

getDragTracker in interface EditPart

Overrides:

getDragTracker in class AbstractGraphicalEditPart

See Also:

EditPart.getDragTracker(Request)

getGuideLayer

public org.eclipse.draw2d.IFigure getGuideLayer()

getModelChildren

protected java.util.List getModelChildren()

Description copied from class: AbstractEditPart

Returns a List containing the children model objects. If this EditPart's model is a container, this method should be overridden to returns its children. This is what causes children EditParts to be created.

Callers must not modify the returned List. Must not return null.

Overrides:

getModelChildren in class AbstractEditPart

Returns:

the List of children

getRulerFigure

protected RulerFigure getRulerFigure()

getRulerProvider

public RulerProvider getRulerProvider()

getTargetEditPart

public EditPart getTargetEditPart(Request request)

Description copied from interface: EditPart

Return the EditPart that should be used as the target for the specified Request. Tools will generally call this method with the mouse location so that the receiver can implement drop targeting. Typically, if this EditPart is not the requested target (for example, this EditPart is not a composite), it will forward the call to its parent.

Specified by:

getTargetEditPart in interface EditPart

Overrides:

getTargetEditPart in class AbstractEditPart

Parameters:

request - Describes the type of target desired.

Returns:

null or the target EditPart

See Also:

EditPart.getTargetEditPart(Request), EditPolicy.getTargetEditPart(Request)

getZoomManager

public ZoomManager getZoomManager()

handleGuideReparented

public void handleGuideReparented(java.lang.Object guide)

handleUnitsChanged

public void handleUnitsChanged(int newUnit)

isHorizontal

public boolean isHorizontal()

setParent

public void setParent(EditPart parent)

Description copied from interface: EditPart

Sets the parent. This should only be called by the parent EditPart.

Specified by:

setParent in interface EditPart

Overrides:

setParent in class AbstractEditPart

See Also:

EditPart.setParent(EditPart)
