Hello,

I enabled DnD-autoscroll in my Treeviewer by setting the
event.feedback=DND.FEEDBACK_SCROLL in the DragOver Method.
It is woking well, but very slowly...
Is it possible to get it faster?

In the eclipse workbench the DnD autoscroll is slow, too.

Regards,
LH

It is controlled by

private static final int SCROLL_HYSTERESIS = 600

in TreeDragUnderEffect.

There is no way for you to change this value. I am looking at making this
faster for 3.1. It would be best if it found an OS setting.

Thanks for information.
It would be nice if it became an editable value.

I'm looking foward to 3.1 ...
