I'm not sure for all the reasons but Table performance is difficult to
match. For example:
Grid grid = new Grid(shell,SWT.VIRTUAL | SWT.V_SCROLL |
SWT.H_SCROLL);
GridColumn column = new GridColumn(grid,SWT.NONE);
column.setWidth(100);
grid.setItemCount(100000);
That code takes about 2100 milliseconds on my system. Run the same
thing with Table and it takes about 20 milliseconds. Thats a huge
difference. Honestly its a little surprising to me that its soo
different. I'm sure there are things I could in Grid for it to be
faster but I doubt I can make up that margin. If you have any insight
it would be much appreciated.

Why would the SWT table be faster on
Windows? Do you have a benchmark?
Hi Ivan,
I've just implemented on small performance fix that should speed up
performance
on population. That being said, the base SWT Table is likely always
going to be faster than Grid (at least on win32 Windows port).

oh! sorry, is my fault. yape! VIRTUAL was implemented. I use the Table
VIRTUAL sample and it works :-) but... like what you had mentioned,
performance
not as snappy as Table control...

Hi Ivan,
Grid currently supports multiple lines in an item by using a
combination
of GridColumn#setWordWrap and Grid#setItemHeight. There is also some
work underway to allow differing heights for different items. See:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=190252
SWT.VIRTUAL has been implemented though there is one outstanding issue
preventing performance from being particularly good. Regardless,
10,000 is not a large number of rows for the tab and that should
populate
extremely quickly with or without SWT.VIRTUAL.

Hi,
Does Grid control able to support multiple lines in a GridItem as what
Table control able ?
What about SWT.VIRTUAL ? This features is good for 10k rows.
Thanks
