findObjectAtExcluding
public EditPart findObjectAtExcluding(org.eclipse.draw2d.geometry.Point pt, java.util.Collection exclude, EditPartViewer.Conditional condition)
Description copied from interface:EditPartViewerReturnsnullor theEditPartat the specified location, using the given exclusion set and conditional. This method behaves similarly toEditPartViewer.findObjectAt(Point).- Parameters:
pt- The mouse locationexclude- The set of EditParts to be excludedcondition- the Conditional used to evaluate a potential hit- Returns:
nullor an EditPart- See Also:

-
fireSelectionChanged
protected void fireSelectionChanged()
Description copied from class:AbstractEditPartViewerFires selection changed to the registered listeners at the time called.- Overrides:
fireSelectionChangedin classAbstractEditPartViewer- See Also:
AbstractEditPartViewer.fireSelectionChanged()
-
hookControl
protected void hookControl()
"Hooks up" a Control, i.e. sets it as the control for the RootTreeEditPart, adds necessary listener for proper operation, etc.- Overrides:
hookControlin classAbstractEditPartViewer- See Also:
AbstractEditPartViewer.unhookControl()
-
reveal
public void reveal(EditPart part)
