+ In fact, leaving at least @a text empty for the stock menu items is strongly
recommended as they will have appearance and keyboard interface (including
standard accelerators) familiar to the user.

For the custom (non-stock) menu items, @a text must be specified and while
@a helpString may be left empty, it's recommended to pass the item
- description (which is automatically shown by the library in the status bar when
- the menu item is selected) in this parameter.

Finally note that you can e.g. use a stock menu label without using its stock
- help string; that is, stock properties are set independently one from the other.

+
+ @code
+ // use all stock properties:
+ helpMenu->Append(wxID_ABOUT);

+ // use the stock label and the stock accelerator but not the stock help string:

+ // use all stock properties except for the bitmap:
+ wxMenuItem *mymenu = new wxMenuItem(helpMenu, wxID_ABOUT);

+ helpMenu->Append(mymenu);
