Question

I am using org.eclipse.jface.fieldassist.AutoCompleteField class to suggest my combo box options. But it’s not useful, because it only suggests entries matching entered text at the beginning.

JavaCode:

   ComboContentAdapter comboAdapter = new ComboContentAdapter();                    
   new  AutoCompleteField(branchCombo,comboAdapter,branchCombo.getItems());

Example :

Combo Box Options:

['ZMEDIA_TWITTER_MIGRATION_BRANCH','ZMEDIA_TWITTER_HOTFIX_BRANCH','ZMEDIA_FB_BRANCH'].

If I type TWITTER in combo box it suggests nothing . It looks like the TWITTER with startswith match in combobox options .

Is there any option to override this?

Thanks You

Simply put, there isn’t.

However, this can be achieved by creating your own proposal provider by implementing org.eclipse.jface.fieldassist.IContentProposalProvider and implementing your filtering logic in its’ getProposals(String contents, int position) method.

Then, just add your proposal provider to a ContentProposalAdapter and adapt the combobox, as follows:

MyContentProposalProvider provider = new  MyContentProposalProvider(combo.getItems());
ContentProposalAdapter adapter = new ContentProposalAdapter(combo, comboAdapter, provider, null, null);
adapter.setPropagateKeys(true);
adapter.setProposalAcceptanceStyle(ContentProposalAdapter.PROPOSAL_REPLACE);
