Calculating/Getting the number of visible rows in a Table [message #371031]

I need to know the amount of visible rows in a table, but i can't seem to
get the formula right.

I have a Shell, which a menu and it contains a table.
I need to know the amount of visible rows, so i tried the following :

int itemHeight =
table.getItemHeight()+table.getGridLineWidth();
_visibleRows =
(shell.getClientArea().height-table.getBorderWidth()-table.g etHeaderHeight()
)/itemHeight;

When the shell i large it calculates too few rows, and then the shell is
very small it calculates to many rows.

Hope you can help

Why not start at table.getTopIndex() and use item.getBounds() for each item
and compare the rect with table.getClientArea()? How about a snippet?
