[Tkinter] Scale 값 command button 파라미터로 호출

Scale

tkinter에는 슬라이드 바인 scale 위젯이 존재한다.

def DrawScale(self):
    scale = tkinter.Scale(self.frame, orient="horizontal", showvalue=True, from_=100, to=0, command=self.CallScale())
    scale.grid(row=0, column=0)

Scale과 함수 연동

scale의 바가 움직일 때마다 CallScale 함수가 호출된다.

def DrawScale(self):
    scale = tkinter.Scale(self.frame, orient="horizontal", showvalue=True, from_=100, to=0, command=self.CallScale())
    scale.grid(row=0, column=0)

def CallScale(self):
    print('CallScale')

CallScale 함수에서 scale 값 출력

def DrawScale(self):
    scale = tkinter.Scale(self.frame, orient="horizontal", showvalue=True, from_=100, to=0, command=lambda value: self.CallScale(value))
    scale.grid(row=0, column=0)

def CallScale(self, value):
    print(value)
