Class BasicTabbedPropertySheetTitleProvider

org.eclipse.core.commands.common.EventManager

org.eclipse.jface.viewers.BaseLabelProvider

org.eclipse.jface.viewers.LabelProvider

org.eclipse.sphinx.emf.ui.properties.BasicTabbedPropertySheetTitleProvider

All Implemented Interfaces:

org.eclipse.jface.viewers.IBaseLabelProvider, org.eclipse.jface.viewers.ILabelProvider

public class BasicTabbedPropertySheetTitleProvider
extends org.eclipse.jface.viewers.LabelProvider

Defines a label provider and a description provider for the title bar in tabbed properties views.

In contrast to Eclipse's built-in TabbedPropertySheetTitleProvider this implementation doesn't initialize the label provider and the description provider in its constructor but lazily when the getImage(Object) and getText(Object) methods are called. This makes sure that label provider and description provider have a chance to get properly initialized by the time where they are really needed and don't remain null when their initialization fails by the time where this class is instantiated.

Since:

0.7.0
