[Octave-bug-tracker] [bug #43664] ginput() freezes upon double-clicking in a fltk figure

[Andreas Weber]

Update of bug #43664 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #1:

I can confirm this with 3.8.2 and on the default branch (although it's much
harder to reproduuce on default).

The reason on stable is, that in __fttk_ginput__.m, line 51

  [x, y, n0, button] = ginput_accumulator (-1, 0, 0, 0)
  until (n0 == n || n0 < 0)


waits until n0 matches exactly the number of requested clicks but if the user
is very fast and double clicks, n0 get 2 and the loop doesn't get aborted. A
solution would be to change this to


  until (n0 >= n || n0 < 0)


and remove the surplus entries in x,y and button. Can someone test how Matlab
behaves on double clicks in ginput?
