How to add Filter to my Combo?

Question

Hi Everyone!

I have a SWT combo box which has items more than 100.

For more efficient selecting, I want to add filter on combo box.

I have searched for this, but I cannot find appropriate comments.

Please let me know what is the best way for this.

Thanks.

Answer 1

As far as I know, SWT uses a simple model of adding an array of Strings as items using the setItems() method, but does not allow filtering like the JFace viewers.

So I think, the only solution is to filter the elements either before adding it using the setItems(), or using the add()/remove() methods (either based on indexing or Strings).

I know it's not pure SWT, but if JFace is okay I find ComvoViewer API gives me the appropriate points, allowing me to to implement my filters. See the ContentProvider API, and specifically the inputChanged lifecycle.
