在我的主要派系小部件中，我有一个包含派系对象的列表。每个派系都有一个名字和团队成员的名字。我不确定绑定(bind)是否是理想的解决方案。如果是这样，我不确定如何进行绑定(bind)？
我怎样才能做到以下几点。 1.在左侧 ListView 中显示派系/团队名称？ 2. 当使用编辑文本创建新的团队名称时，它会更新左侧的 ListView 。 3. 选择一个团队后，它会填充右侧的列表，显示团队成员的姓名。 4. 当用户输入新成员名称时，它会被添加到左侧选定的团队中。

最佳答案
您可以利用 returnPressed() 来做到这一点在您的 NameListWidget 小部件中发出信号:
在initUI中:
self.nameInput.returnPressed.connect(self.pressed_return)
然后创建 pressed_return 方法，仍然在您的 NameListWidget 中。
def pressed_return(self):
self.nameList.addItem(self.nameInput.text())
self.nameInput.clear()
这会将当前值添加到列表中，然后清除 QLineEdit。
关于python - 使用python，绑定(bind)在pyside QListWidgets中显示对象列表？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33418245/
