The usage of Fl_Menu_Item user_data is not clear to me and might either need some documentation or an extension of the Fl_Menu_:value(...) method:

In my case I store the text corresponding to an Fl_Choice menu item in a settings file. When I reload a previously saved settings file later on and try to set the Fl_Choice widget according to the text, there is the inherited method Fl_Menu_:find_item(text) method which allows me to retrieve the corresponding menu_item user_data. However, unlike in C++ fltk, a call to Fl_Menu_:value(user_data) does not work, apparently only the Fl_Menu_:value(index) version has been translated to lua. Therefore, as a work-around, I currently have to determine the index by looping over the user_data returned by Fl_Menu_:menu(i) and compare the texts manually. This is pretty cumbersome. Also, unlike one would expect in Lua, one has to loop like in C++ from 0 to Fl_Menu_:size()-1.

My suggestion to improve this would be an extension of the Fl_Menu_:value() method to allow also menu item user_data as input.

[Update]
Additionally, calls to Fl_Menu_Item:labelsize() seem currently useless. They always return 0 irrespectively to any value passed before.

Regards,
Gerald
