for some reason, Qt is trying to find the slot in QWidget instead of ur mwnd class

Qt Code: 
  1. Object::connect: No such slot QWidget::geometryClicked(Geometry*,QPoint) in src/mwnd.cpp:28
  2. Object::connect: No such slot QWidget::mouseEventCoordinate(QMouseEvent*,QPointF) in src/mwnd.cpp:46
To copy to clipboard, switch view to plain text mode 

..does ur class have any such parenting? could you elaborate a bit on code of mwnd?
