My Eclipse e4 application contains a TrimmedWindow. This menu cannot be moved or closed. Now I'm searching a way to disable max/min/close of that Trimmedwindow.

Is there some tag available for the trimmedwondow or can I do this in code without fullscreen enabling?

Hi Engin,

One possibility is to register a model processor in one of your plugin.xml like this:

<extension
id="id1"
point="org.eclipse.e4.workbench.model">
<processor
apply="initial"
beforefragment="true"
class="esa.egoscc.gsmccc.product.model.TrimBarDecorator">
</processor>
</extension>

Then, create your model processor class. In my example I remove completely the main trim bar of the main application window:

public class TrimBarDecorator
{
@Inject
@Optional
private MWindow window;

@Execute
public void modifyTrimBar(MApplication app)
{
if (this.window == null)
{
this.window = app.getChildren().get(0);
}
this.window.getPersistedState().put(IPresentationEngine.STYLE_OVERRIDE_KEY, String.valueOf(SWT.NO_TRIM));
}
}

Best regards,
David
