Constructor Detail

def : UInt64, marshal : GObject::ClosureMarshal | Nil, params : Enumerable(Gtk::Expression), callback_func : GObject::Callback, user_data : Pointer(Void) | Nil, user_destroy : GObject::ClosureNotify | Nil) : self #

Creates a Gtk::Expression that calls callback_func when it is evaluated.

This function is a variant of that creates a GClosure by calling g_cclosure_new() with the given callback_func, user_data and user_destroy.
