[news.eclipse.platform.rcp] Re: How to add a menu to a toolbar

[Reinhard Moser <moser@xxxxxxxx>]

Hi hombre,

  i added a drop down box for change the author. First create an action 
which implements IMenuCreator and extends Action like this:

package at.healthgate.ebmrc.client.actions;

import org.eclipse.jface.action.Action;
import org.eclipse.jface.action.IMenuCreator;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Menu;

public class TestAction extends Action implements IMenuCreator {

  private Menu menu_ = null;

  public void dispose() {
    if ( this.menu_ != null ) {
      this.menu_.dispose();
      this.menu_ = null;
    }
  }

  public Menu getMenu( Control parent ) {
    if ( this.menu_ != null )
      this.menu_.dispose();
    this.menu_ = new Menu( parent );
    // FILL menu with actions
    return this.menu_;
  }

  public Menu getMenu( Menu parent ) {
    return null;
  }

}

Afterwards you add the menu to your coolbar in the ActionBarAdvisor:

protected void fillCoolBar( ICoolBarManager _cool_bar_manager ) {
  super.fillCoolBar( _cool_bar_manager );
  IToolBarManager tool_bar_manager = new ToolBarManager( 
_cool_bar_manager.getStyle() );
  tool_bar_manager.add( new Separator( "user" ) );
  AuthorChangeAction author_change_action = new AuthorChangeAction();
  tool_bar_manager.add( author_change_action );
  ToolBarContributionItem toolbar_contribution_item = new 
ToolBarContributionItem(tool_bar_manager );
  _cool_bar_manager.add( toolbar_contribution_item );
}

For me this works.
