Gtk.jl - GTKFileChooserButton question

General Usage
6 
function on_fileChooser_file_set(var)
	filename = Gtk.bytestring(Gtk.GAccessor.filename(var),true)
	println("this is the filename: ", filename)
	#println("I'm here.")
end

I cannot test because I don’t have the glade file. Best thing to test is that you provide a minimal working example (MWE). Instead of providing the glade file, you can also paste the content of the glade file into a string my_ui_string and call GtkBuilder(buffer=my_ui_string).
