hello
I am trying to create a table . But I am unable to set it's size.to be
more precise, the size changes according to the no of elements. But my
requirement is to show only 10 elements in table with scroll bars. I
tried variuos methods but , no effects.
I tried to use the redraw methos which sets the size with scrollbars ,
but nothing appears in the table.
please find attached the method where I am creating table.
thanks
Prameela

Hi Prameela,
don't pack your table. If you pack it it will be resized and that is
what you want to avoid. Set the size of your table explicitely.
