Is there currently any support for controlling autoscrolling?
I am using an extension of GraphicalEditorWithFlyoutPalette that has a bunch
of parts and associated figures, and am looking for a way to autoscroll the
window if I drag a figure near the edge of the view. Imagine something like
dragging some cells around in Excel - as you get near the edge, the
spreadsheet starts to scroll in that direction...
Also, is there a way to disable the mousewheel while dragging an object? It
seems that when scrolling using the mouse wheel and dragging an object, the
coordinates don't update as expected (ie: if I start dragging something and
scroll down with the mouse wheel, the figure I'm dragging is still relative
to the same co-ordinates it was, and the mouse pointer is now way off from
the object, effectively making the scrolling more harmful than helpful in
placing the object further down.
Any help on this at all would be appreciated. Thanks!
Christine

ScalableFreeformRootEditPart already does that. ScalableRootEditPart should
be doing the same. Open a bug report.
