[Octave-bug-tracker] [bug #49157] textbox annotation generates an error with gnuplot backend

[Dan Sebald]

Follow-up Comment #3, bug #49157 (project octave):

Works "fine" here as well.  That error message is coming from this line:


    switch (obj.type)
      case "image"
[snip]
      otherwise
        error ("__gnuplot_draw_axes__: unknown object class, %s", obj.type);
    endswitch


which is a very long switch statement that processes all the various graphics
objects.  Somehow a uicontextmenu was making its way through to the
__gnuplot_draw_axes__.m file.  In the latest code, __gnuplot_draw_figure__.m
has this check on the object:


          case {"uimenu", "uicontextmenu"}
            ## ignore uimenu objects
            kids(i) = [];
          otherwise
            error ("__gnuplot_draw_figure__: unknown object class, %s",
type);
        endswitch


Hence, the latest code is weeding out the 'uicontextmenu' objects.  I'm
guessing that wasn't in Octave release 4.0.3 yet.
