If I understand your situation, you want to modify widgets from a spawned thread. You cannot do that, but you should send a widget-state-change request to the main thread using Idle class.
import glib.Idle; void aThreadFun(){ new Idle(delegate bool(){ // Modify your widget here. Redraw etc. return false; }); }
