Package org.eclipse.ease.ui.tools

Class ToggleHandler

java.lang.Object

org.eclipse.core.commands.common.EventManager

org.eclipse.core.commands.AbstractHandler

org.eclipse.ease.ui.tools.ToggleHandler

All Implemented Interfaces:

IHandler, IHandler2, IElementUpdater

public abstract class ToggleHandler
extends AbstractHandler
implements IElementUpdater

Use this handler for style="toggle" command contributions. You need to declare a state for your command to use ToggleHandler:

 <command id="somecommand" name="SomeCommand">
    <state class="org.eclipse.jface.commands.ToggleState" id="STYLE"/>
 </command>
 

The id="STYLE" was chosen because of IMenuStateIds.STYLE - maybe this will work without any Handler foo in later Eclipse versions. See http://www.ralfebert.de/eclipse/2009_01_21_togglehandler/ http://eclipsesource.com/blogs/2009/01/15/toggling-a-command-contribution/
