Quick find (Ctrl + F) does not work for virtual Table Viewer [message #1077094]

Our application is an RCP application and needs to display table of several thousands items. For this reason, we're setting SWT.VIRTUAL in our TableViewer's constructor. That works pretty well except for finding text using find text-box (Ctrl+F).

We're having following issue :

Our TableViewer support sorting and filtering. When we use a virtual tableviewer and try to find text in the table by either typing the text or by opening find text-box (by clicking Ctrl+F) at the lower-right corner and entering the text, the find text-box does not open to find the text.

Using a non virtual TableViewer, everything works fine.

Is this a known bug / issue?

Please suggest some pointers or alternative work around.

Thanks for the answers.

First of this is a feature only available on Linux and provided by GTK.
The problem is that a virtual viewer creates its TableItems on demand so
a text search can't work.

Hi Thomas,

Thanks for your reply.

Actually we cannot remove SWT.VIRTUAL option from the table viewer as there are more than hundred thousand elements (rows) in the table. Hence we need some fix for quick find to work in virtual Table.
Please suggest any pointer for the same.

Thanks for the answers.

You need to do the search yourself inside your domain elements,
calculate the index and then reveal this item.
