I¹ve fixed this. The edges (tubing) aren¹t being used during picking. I
modified the class in the following way:
1)Allow translating the plane by setting the ivar ³TranslateByTubing²
2) If ³TranslateByTubing² is on, ³Tubing² is turned on (if it isn¹t already)
and the ³EdgeActor² added to the pick list. If ³TranslateByTubing² is turned
off, ³EdgeActor² is removed from the pick list, ³Tubing² is left unmodified.
3) During ³OnLeftMouseDown², check if ³TranslateByTubing² is on and
³EdgesActor² is the picked prop. If true highlight the plane and set the
state to pushing.
Anyway, I have the patch for this but there is a previous patch that hasn¹t
been merged into the trunk yet on the same class:
http://www.vtk.org/Bug/bug_view_advanced_page.php?bug_id=8669.
Patch is in this bug...note that this patch also contains the fixes for the
previous bug since it hadn¹t been checked in yet.
