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:

AbstractGraphicalEditPart.activate()

createAccessible

protected AccessibleEditPart createAccessible()

returns the AccessibleEditPart for this EditPart. This method is called lazily from getAccessibleEditPart().

createEditPolicies

public 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)

createToolTip

protected org.eclipse.draw2d.IFigure createToolTip()

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:

AbstractGraphicalEditPart.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

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:

AbstractGraphicalEditPart.getDragTracker(Request)

getImageCache

protected static PaletteEditPart.ImageCache getImageCache()

Returns the image cache. The cache is global, and is shared by all palette edit parts. This has the disadvantage that once an image is allocated, it is never freed until the display is disposed. However, it has the advantage that the same image in different palettes is only ever created once.

getModelChildren

public 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

See Also:

AbstractEditPart.getModelChildren()

getPaletteEntry

protected PaletteEntry getPaletteEntry()

getPreferenceSource

protected PaletteViewerPreferences getPreferenceSource()

getToolTipFigure

protected org.eclipse.draw2d.IFigure getToolTipFigure()

getToolTipText

protected java.lang.String getToolTipText()

nameNeededInToolTip

protected boolean nameNeededInToolTip()

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent evt)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

See Also:

PropertyChangeListener.propertyChange(PropertyChangeEvent)

restoreState

public void restoreState(org.eclipse.ui.IMemento memento)

saveState

public void saveState(org.eclipse.ui.IMemento memento)

setImageDescriptor

protected void setImageDescriptor(org.eclipse.jface.resource.ImageDescriptor desc)

setImageInFigure

protected void setImageInFigure(org.eclipse.swt.graphics.Image image)
