A small and short demo app would nice. Or guideline and

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;
    });
