Details:

There doesn't seem to be a clean way to remove a context menu from a figure:


% By default, uicontextmenu is []
F = figure;
get(F,'uicontextmenu')

% add a uicontextmenu
c = uicontextmenu;
m = uimenu('parent',c,'label','menu');
set(F,'uicontextmenu',c);

% => error
set(F,'uicontextmenu',[]);

% => deleted but remains as invalid handle
delete(get(F,'uicontextmenu'))
get(F,'uicontextmenu')
get(get(F,'uicontextmenu'))
