public RootTreeEditPart()

Method Detail

addChildVisual

protected void addChildVisual(EditPart childEditPart,
                              int index)

This is where the child gets added. No TreeItem is needed here because the contents is actually represented by the Tree iteself.

Overrides:

addChildVisual in class AbstractEditPart

Parameters:

childEditPart - EditPart of child to be added.

index - Position where it is to be added.

createEditPolicies

protected void createEditPolicies()

Description copied from class: AbstractEditPart

Creates the initial EditPolicies and reserves slots for dynamic ones. Should be overridden to install the inital edit policies 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.

Overrides:

createEditPolicies in class AbstractEditPart

Following copied from class: org.eclipse.gef.editparts.AbstractEditPart

See Also:

AbstractEditPart.doInitialize(), AbstractEditPart.installEditPolicy(Object, EditPolicy)

getCommand

public Command getCommand(Request request)

Description copied from interface: EditPart

Returns the command to perform the given Request or null.

Specified by:

getCommand in interface EditPart

Overrides:

getCommand in class AbstractEditPart

Following copied from class: org.eclipse.gef.editparts.AbstractEditPart

Parameters:

Request - A request describing the command to be created.

See Also:

EditPolicy.getCommand(Request)

getContents

public EditPart getContents()

Specified by:

getContents in interface RootEditPart

getDragTracker

public DragTracker getDragTracker(Request request)

Description copied from interface: EditPart

Return a drag tracker for dragging this EditPart. The SelectionTool makes such requests, but other Tools may also do so.

Specified by:

getDragTracker in interface EditPart

getRoot

public RootEditPart getRoot()

Returns itself

Specified by:

getRoot in interface EditPart

Overrides:

getRoot in class AbstractEditPart

getViewer

public EditPartViewer getViewer()

Return the viewer that this root view object lives in.

Specified by:

getViewer in interface RootEditPart

Overrides:

getViewer in class AbstractEditPart

Parameters:

viewer - org.eclipse.gef.IGEFViewer The viewer.

getWidget

public Widget getWidget()

Specified by:

getWidget in interface TreeEditPart

removeChildVisual

protected void removeChildVisual(EditPart childEditPart)

This is where the child gets removed. This method is overridden here so that the AbstractTreeEditPart does not dispose the widget, which is the Tree in this case. The tree is owned by the viewer, not the child.

Overrides:

removeChildVisual in class AbstractEditPart

Parameters:

childEditPart - EditPart of child to be removed.

setContents

public void setContents(EditPart editpart)

Specified by:

setContents in interface RootEditPart

setViewer
