Class MultiButtonCellEditor
java.lang.Object
org.eclipse.jface.viewers.CellEditor
org.eclipse.gmf.runtime.common.ui.services.properties.extended.MultiButtonCellEditor
-
Direct Known Subclasses:
-
PropertyPageCellEditor
-
public abstract class MultiButtonCellEditor
- extends
CellEditor
Cell editor that provides for a read-only label representation of the value
and multiple buttons at the end. The last button receives the focus. The
subclasses have to override the initButtons() method. The implementation of
that method should only make calls to the method addButton() to initialize
the desired buttons.
