| Virtual Table page size. [message #103207] |

Hi,
I'm using a TableViewer with a VIRTUAL table, currently everything works
fine, just when I scroll down the "..." appear stating that the next
batch of data is loading.
My question is, can I define a "page" size so I can force that the
viewer loads more than the visible number of records?
Thanks
Tiago

Hi Tiago,
you can set a "virtual" size at first using setItemCount(), e.g. 100. If
you get close to this item count in LazyContentProvider#updateElement(),
you can then increase the itemCount by your page size, e.g. to 200.
Is this what you mean?
Regards,
Stefan.

Hi Stefan,
Something like that, can you give me a small example?
Thanks.

Hi Tiago,
you can find an example attached to RAP-Bug 241049 in bugzilla:
https://bugs.eclipse.org/bugs/attachment.cgi?id=107576
There is a model which grows when the user scrolls down near to the end
of the list.
Regards,
Stefan.
