Python의 확인란을 사용하여 트리보기를 만드는 방법

Question

저는 Tkinter와 Tix를 사용하여 작은 프로그램을 작성했습니다. 트리 뷰에서 항목을 선택할 수 있도록 체크 박스 (체크 버튼)가있는 트리보기가 필요한 시점에 있습니다. 쉬운 방법이 있나요? 나는 ttk.Treeview()를보고 있었고 트리보기를 쉽게 볼 수 있지만보기에 체크 버튼을 삽입하는 방법이 있습니까?

간단한 코드 스 니펫은 정말 감사하겠습니다.

나는 ttk에 국한되지 않습니다. 아무거나는 할 것이다; 한 내가 예 또는 좋은 문서를 가지고 나는 내가 ttk.Treeview을 상속 체크 박스와 트 리뷰 클래스를 만들어

Answer 1

import Tix 

class View(object): 
    def __init__(self, root): 
     self.root = root 
     self.makeCheckList() 

    def makeCheckList(self): 
     self.cl = Tix.CheckList(self.root, browsecmd=self.selectItem) 
     self.cl.pack() 
     self.cl.hlist.add("CL1", text="checklist1") 
     self.cl.hlist.add("CL1.Item1", text="subitem1") 
     self.cl.hlist.add("CL2", text="checklist2") 
     self.cl.hlist.add("CL2.Item1", text="subitem1") 
     self.cl.setstatus("CL2", "on") 
     self.cl.setstatus("CL2.Item1", "on") 
     self.cl.setstatus("CL1", "off") 
     self.cl.setstatus("CL1.Item1", "off") 
     self.cl.autosetmode() 

    def selectItem(self, item): 
     print item, self.cl.getstatus(item) 

def main(): 
    root = Tix.Tk() 
    view = View(root) 
    root.update() 
    root.mainloop() 

if __name__ == '__main__': 
    main()

작동 할 수 있지만, 체크 박스는 ttk.Checkbutton 만의 이미지되지 않습니다 체크, 체크되지 않은 체크 박스 및 삼중 체크 박스.

CheckboxTreeview의 개선 된 버전 ttkwidgets 모듈에서 사용할 수있다.
