+
+    This class provides several functions for customizing the menu items
+    appearance that are available only in wxMSW port. These functions should
+    not be used in portable programs and, moreover, have some known limitations
+    even in wxMSW: using them switches the menu item in a "owner drawn" mode,
+    where it is painted by wxWidgets itself and not the system, which may
+    result in a slightly different appearance for it. Owner drawn items are
+    also incompatible with dark mode support and using them makes the entire
+    menu containing them to use standard light mode colours even in dark mode.
