xml 설명 파일을 사용하여 pyGObject로 GUI를 만들었으며 GtkTreeView으로 사이드 바를 만들려고합니다. GtkTreeView은 일부를 추가 했는데도 텍스트를 내 GUI의 헤더와 하위에 표시하지 않습니다. 왜 그런가요? 어떻게 해결할 수 있습니까?GUI (PyGObject)에 누락 된 텍스트
사이드 바는 다음과 같이해야 :
Parent 1
Child 1
Child 2
Child 3
등
내 코드의 짧은 버전은 다음과 같습니다.
App.py
#!/usr/bin/env python2
from gi.repository import Gtk
class AppUI:
def __init__(self):
self.builder = Gtk.Builder()
self.builder.add_from_file("app.xml")
self.window = self.builder.get_object("main-window")
self.sidebarStore = self.builder.get_object("sidebar-store")
for parent in range(4):
piter = self.sidebarStore.append(None, ['parent %i' % parent])
for child in range(3):
self.sidebarStore.append(piter, ['child %i of parent %i' % (child, parent)])
self.handlers = {
"onDeleteWindow": Gtk.main_quit,
}
self.builder.connect_signals(self.handlers)
self.window.show_all()
UI = AppUI()
Gtk.main()
