[Octave-bug-tracker] [bug #44763] Reset submenus of a uicontextmenu

[Rik]

Follow-up Comment #3, bug #44763 (project octave):

This is still present on the development branch (6.0).

I suspect the problem is that calling uimenu() to add the submenu invokes
extra code that checks whether there is an existing menu, etc., and makes
changes to the menu.  Then, when you delete the submenu, it just deletes the
actual graphics object.  There probably needs to be destructor code written
for the submenu that is called automatically by delete() to freshen the parent
uimenu.
