Description Alexander Nyßen

2014-06-10 14:20:26 EDT

For end-users, waypoint-related operations (bending of curves) show the following inconsistencies:

1) waypoints cannot be deleted when dragging them onto end points
2) when inserting a new waypoint, it cannot be deleted by dragging onto another waypoint or end point before the creation has been committed.

We will have to adjust this.

Furthermore, when deleting a waypoint, the handle is shortly visible at position (0,0).  We should ensure that does not happen.

Comment 2 Alexander Nyßen

Fixed indices and parameters were not properly assigned to handle parts and ensured updates are only performed on those handles that are actually affected (by sorting them and only updating the indices if needed). Thereby, the problem documented in comment #1 does no longer apply. What remains is a solution for 1) and 2).

Comment 3 Matthias Wienand

Fixed deletion of waypoints when dragging a newly created waypoint onto another waypoint (issue 2). The first issue remains.

Comment 4 Matthias Wienand

Implemented deletion of the first/last waypoint when dragging it onto the start/end point of the connection. Unfortunately, you still cannot delete the first/last waypoint by dragging the start/end point onto it.

Comment 5 Matthias Wienand

Updated list of issues:
 1) Waypoints cannot be deleted when dragging end points onto them.
 2) Hover feedback is missing for waypoint handles.
 3) Hover feedback is missing for connections.

Comment 6 Matthias Wienand

All issues have been resolved and the relevant code is published on the master branch. Therefore, I am changing the status to RESOLVED, FIXED.
