annotate libgui/graphics/Menu.cc @ 23224:73f7ef7169ac
Make uimenu "Position" property Matlab-compatible (bug #50369).
* Menu.cc (Menu::Menu, Menu::update, Menu::updateSiblingPositions):
Don't skip objects which belong to "builtinMenu" when processing uimenus.
* Figure.cc: Correct typo in comment "mennubar" -> "menubar".
