# 여러 QCheckBox의 stateChanged slot 처리 방법 

## slot에 QCheckBox 객체를 넘겨 처리하는 방법

class checkdemo(QWidget):

   def __init__(self, parent = None):

      super(checkdemo, self).__init__(parent)

## QButtonGroup을 만들어 처리하는 방법

<pre>

self.bg = QButtonGroup()

self.bg.addButton(self.b1,1)

self.bg.addButton(self.b2,2)

self.bg.buttonClicked[QAbstractButton].connect(self.btngroup)

def btngroup(self,btn):

   print btn.text()+" is selected"

</pre>
