ProgressBar 위젯에 쓸만한 메서드

표시줄을 앞뒤로 왔다갔다 하게 하는 pulse() 대신, ProgressBar를 표시줄 비율(0.0과 1.0 값도 해당하는 사이 float 값)만큼 완료 의미로 "채워 넣는"다면, set_fraction(fraction)을 사용하십시오.

텍스트를 설정하고 보여주려면 (표시줄에 겹쳐 나타남) set_text("text")와 set_show_text(True)를 사용하십시오. 텍스트를 설정하지 않았고 set_show_text(True) 함수를 호출하면 나타나는 텍스트는 작업 완료 백분율입니다.
