[python]파이썬_Tkinter_엑셀형식_Entry입력(ScrollableFrame, Entry)

Tkinter Entry ( 입력 폼을 가로 3개 세로 10개 입력)

---

bg = []
cnt = 0
for i in range(10):
	for j in range(3):
		bg.append( tk.Entry(frame.scrollable_frame, text="", width=17))
		bg[cnt].grid(row = i, column = j)
		cnt += 1

 

3 x 10 Entry 객체

 

Scrollbar 및 결과를 확인 하기 위한 Button 추가

---

ScrollableFrame : 프레임에 스크롤이 달린 객체 ( 스크롤에 따라 프레임 위치 결정)

Button 추가 : checkEmpty() 기능 추가

checkEmpty() : 모든 Entry 값 확인하여 빈칸 갯수 Count
