hi,

I define a coolbar in my view using this code :

// define a CommandContributionItem
IWorkbenchWindow window = getSite().getWorkbenchWindow() ;
CommandContributionItemParameter p = new CommandContributionItemParameter(
window, "",
"myCommandID",
SWT.PUSH);

CommandContributionItem contributionItem = new CommandContributionItem( p );

// I define coolbar in my view
CoolBar coolBar = new CoolBar( coolBarContainer, SWT.FLAT );

final IToolBarManager toolbar = new ToolBarManager(SWT.FLAT | SWT.RIGHT);

// add my CommandContributionItem to the toolbar
toolbar.add( contributionItem ) ;

ToolBarContributionItem toolBarContributionItem = new ToolBarContributionItem( toolbar, "model") ;

toolBarContributionItem.fill(coolBar, 0) ;

In the same view ,there is a TreeViewer , the command should be enabled if and only if a certain type of node of the TreeViewer is selected.

how to define the enabledwhen of the command ?

thanks!

Where is your handler defined for that command? In the plugin.xml, it's org.eclipse.ui.handlers that defines an enabledWhen clause for a handler. If it was activated programmatically in your view, it's your handler that contols its enabled state.
