Re: [fltk.general] Re: Use native parent window with fltk widgets to retain Mac menubar of parent application - Forums

I think we are talking about the same thing. Basically, if the FLTK program does not make any calls to Fl_Sys_Menu_Bar, then the menu bar on the top of the mac is left absolutely unchanged (either as whatever another toolkit set it to, or whatever the default behavior of Mac is when you don't do anything). It sounds like the current FLTK messes with the top menu when the programmer does nothing, which I don't think is correct behavior.

For avoiding having to change your code depending on the platform, I think a window subclass (MainWindow?) would work. If a Sys_Menu_Bar is set up on a system that does not have such a menubar, these windows move all the widgets down sufficiently and add a regular MenuBar. This would allow the programmer to select what window(s) get menu bars, rather than a single one or all of them.

It would certainly be nice if this "no window menu" behavior was automatic if the fltk program did not try to set the main menu!

I'm not sure to grasp what exactly is meant here, but I've seen one situation that could be improved :
when FLTK is used on macOS while another toolkit creates the mac system menu.
The git repository for 1.4 now supports such situation without asking the user to set explicitly
Fl_Sys_Menu_Bar::window_menu_style(Fl_Sys_Menu_Bar::no_window_menu);
