Sure get access to the model and call setEnabled() but often this is
controlled by the Command-Attached to it.

As Tom mentioned, both a Handled tool item and direct tool item work by
querying the handler's @CanExecute method (where the direct tool item
handler is simply a contribution object).

If you are the handler, you can return true/false from your @CanExecute
method.

My xwt contains the following
..
<ToolBar x:style="SWT.NONE">
<ToolItem x:Data="test" x:style="SWT.PUSH" SelectionEvent="onTI1Clicked"
image="/icons/sample.gif" Loaded="performToolItemLoaded"></ToolItem>
<ToolItem x:Data="test1" x:style="SWT.PUSH"
SelectionEvent="onTI2Clicked"
image="/icons/sample.gif" Loaded="performToolItemLoaded"></ToolItem>
</ToolBar>

The ToolItem getControl is null as demonstrated with this snippet.

Map oM = new HashMap ( ) ;
public void performToolItemLoaded(Object object, Event event) {
ToolItem oTI = (ToolItem) event.widget;
System.out.println ( oTI.getData() ) ;
oM.put(oTI.getData(), oTI) ;
}
public void onTI1Clicked(Object object, Event event) {
ToolItem oTI = (ToolItem) event.widget;
System.out.println ( oTI.getData() ) ;
oTI = ( ToolItem ) oM.get ( "test1" ) ;
if ( oTI.getControl ( ) == null )
System.err.println ( "test1 control: " + oTI.getControl ( ) ) ;
else
oTI.getControl().setEnabled(false) ;
}
public void onTI2Clicked(Object object, Event event) {
ToolItem oTI = (ToolItem) event.widget;
System.out.println ( oTI.getData() ) ;
}

How do I disable a tool item when another tool item is clicked ?

Thanks
- Walter

Hi,

Ok you should have been more specific in your question. The answer from
me and Paul was about the e4-Workbench-ToolItems while you are talking
about XWT.

I'd suggest for the future that people use [xwt] in the subject if their
question is on this topic.
