Hi,

In all trees, shows the behavior that if we extended the tree and the tree becomes an "out of the window does not disappear automatically scrolls to the top. So you open an entry, the expansion of the tree is shown, however, outside the visible window, so that the user must manually scroll down. This will ensure that the tree is scrolled automatically.

How can i do that the tree scroll automatically.

Thanks

Hi,

unfortunately, Tree#setTopItem( TreeItem ) is still not implemented in
RAP. See:
285890: [Tree] setTopItem is missing
https://bugs.eclipse.org/bugs/show_bug.cgi?id=285890
This will be fixed in 1.4 release.

HTH,
Ivan
