Hello, world!

Is it possible to use a Menu widget on a Combo instead of the usual addItems() method? Or otherwise, how can I add separators to the Combo dropdown? Menu would be better because I can associate an Object with each item.

Thanks!

Hi,

There isn't a way to do this for Combos, I don't know if the native controls
provide support for separators like this.

If this is important then a workaround you can try is to create a ToolBar
with a SWT.DROP_DOWN ToolItem, and provide the menu (which can contain a
separator) when needed. For an example of this see
http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org. eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet67. java .

Hm, I don't know if that will work for my application. Is there any way to set an item in the Combo as non-selectable?

No, there isn't a way to do this. But a menu item can be disabled ;-).
