SWT ComboViewer with ContentProposal and Pagination Control (large anmount of data) [message #1319701]

Hi Everyone

I have implemented a ComboViewer that also uses content proposal (ContentProposalAdapter) functionality in Eclipse RCP application (using SWT). User is able to type first letter of e.g. a street and he gets all valid proposals e.g. streets that starts with 'Mac'. It works really great. Now I am facing additional problem. Number of data to show in this combo can be very big. Now I got almost 200000 records to show. Creating Combo element in GUI takes forever and it crashes my RCP application. I thought about introducing pagination control for this ComboViewer. I would like it to work very similar to this ExtJs solution:

dev.sencha.com/deploy/ext-4.0.1/examples/form/forum-search.html

What I was able to find is Nebula Pagination Control (https://www.eclipse.org/nebula/widgets/pagination/pagination.php) I found just examples where it is user in grid, but not in a combo. There is something like PageableTable, but it is something way different that I need (Although in here: dev.eclipse.org/mhonarc/lists/nebula-dev/msg01669.html it is said that it will copied from ContentProposalAdapter ) Does anyone have any example of combining pagination control with ComboViewer? Can Nebula component support this kind of functionality ?

cheers

Hi.
I am not aware of any lazy combo viewer. I am not able to find any information online. Can you give me any direction (link or something) ?

cheers,

Thanks for the information. It is very similar to Nebula where it is allowed just for table and tree.

Pawel we have the TableCombo widget [1].

Other that this, I am afraid we don't have what you are looking for. We would be very happy with such a contribution Wink
