Multiline ultratree node scrolling issue
posted

Hi,

I have run into an issue with a tall multiline node in an Ultratree.  When the node height is greater than the height of the tree, I get a vertical scrollbar but when I try to scroll down, the display jumps to show the next node in the tree at the top of the window.  So the text at the bottom of the very tall node can never be scrolled into view.  I'm using the latest version and still have this issue.  It only happens when a node is very tall and can't fit entirely in the window.  If no single node is too tall, the tree scrolls properly.

Is this a known problem, and is there a way around it?

Thanks,

Cassio Nishiguchi

    Hi Cassio,

    The tree's scrolling is node-based. In other words, the scrollbar always scrolls such that a node is positioned flush against the top of the tree.

    In order to achieve what you want, the scrolling would have to be pixel-based, allowing you to scroll part of a node into view. There is no way to do that.

    What you should do is set up your application such that the user can resize the tree and/or ensure that no nodes are taller than the height of the entire tree.
