Not scroll when related scrollbar disposed [message #1296582]

Hi, all

I want to realize the effect of scrolling by code rather than by drag the scrollbar of a tree, so I dispose the scrolbar using the code like :

tree.getVerticalBar().dispose();

and in another event listener I write like :

tree.setTopItem(specifiedItem);

I found that the second code only works under the situation that the scrolbar is not disposed, but Why?

And this is different from a table widget, since I can control the scrolling of a table even its related scollbar is disposed.

Who can explain this?
Thanks.

Robin.

Using the code example at http://www.java2s.com/Tutorial/Java/0280__SWT/Fixedfirstcolumnandhorizontalscrollremainingcolumns.htm I can dispose the vertical scrollbar of the left table and it is still sync with the right table, but when I change the left table to a tree, it only works that the vertical scrollbar of the tree is not disposed.

Who can explain this or sovle my issue?
Any suggestions would be appreciated.

Robin.
