Function Documentation

fl_mac_set_about()

void fl_mac_set_about	(	Fl_Callback *	cb,
		void *	user_data,
		int	shortcut = 0
	)

Attaches a callback to the "About myprog" item of the system application menu.

For back-compatibility. Equivalent to Fl_Sys_Menu_Bar::about(Fl_Callback *cb, void *user_data).

fl_open_callback()

void fl_open_callback

(

void(*)(const char *)

cb

)

Register a function called for each file dropped onto an application icon.

This function is effective only on the Mac OS X platform. cb will be called with a single Unix-style file name and path. If multiple files were dropped, cb will be called multiple times.

This function should be called before fl_open_display() is called, either directly or indirectly (this happens at the first show() of a window), to be effective for files dropped on the application icon at launch time. It can also be called at any point to change the function used to open dropped files. A call with a NULL argument, after a previous call, makes the app ignore files dropped later.

Variable Documentation

fl_mac_os_version

int fl_mac_os_version

extern

The version number of the running Mac OS X (e.g., 100604 for 10.6.4, 101300 for 10.13, 140102 for 14.1.2).

FLTK initializes this global variable before main() begins running. If the value is needed in a static initializer, a previous call to Fl::system_driver() makes sure fl_mac_os_version has been initialized.
