// Native GTK is not thread safe, and thus, gotk3's GTK bindings may not
// be used from other goroutines. Instead, glib.IdleAdd() must be used
// to add a function to run in the GTK main loop when it is in an idle
// state.
//
// Two examples of using glib.IdleAdd() are shown below. The first runs
// a user created function, LabelSetTextIdle, and passes it two
// arguments for a label and the text to set it with. The second calls
// (*gtk.Label).SetText directly, passing in only the text as an
// argument.
//
// If the function passed to glib.IdleAdd() returns one argument, and
// that argument is a bool, this return value will be used in the same
// manner as a native g_idle_add() call. If this return value is false,
// the function will be removed from executing in the GTK main loop's
// idle state. If the return value is true, the function will continue
// to execute when the GTK main loop is in this state.
