Hi,
In my application, there is a tree with only two levels but which will contain at least 25.000 roots. What's more, my tree has 14 columns.
I would like to use Xviewer which offers a range of very efficient and interesting functionnalities.
However, the problem is that, in my case, the tree is loading excessively slowly. It looks like SWT.VIRTUAL is not active.
Is the slow loading normal? If so, how can the loading time be reduced?
It appears that, in JFace, there are problems involving trees (not tables) with SWT.VIRTUAL.
Thus, I have the following performance (if I change my tree to a table by removing one level)
25,000 nodes - Tree SWT.VIRTUAL -> > 20 sec
25,000 nodes - Table SWT.VIRTUAL -> > 2 sec
So, if in XViewer the problem with these data volumes stems from the fact that it is a tree, is it possible to change the tree to a table?
If so, how?
Or is there a "table" version of Xviewer?
Thank you.
Best regards,
Pascal.

Hi,
We have not publicly announced yet but we are currently working on a
high-performance-feature rich Grid-Framework.
Only problem - it requires Java8 - the underlying control is currently
Nebula-Grid but because the Facade does not impose an UI-Toolkit
information the internal implementation could be fairly everything.
We also don't yet support Tree functions which we'd need someone to fund!
See https://github.com/BestSolution-at/framework-grid
