如何在Kivy中禁用小部件? [英] How to disable a widget in Kivy?

问题描述

我阅读了Kivy教程，找不到如何禁用小部件(例如，按钮).

I read the Kivy tutorial and couldn't find how to disable a widget (for example, a Button).

def foo(self, instance, *args):
  #... main business logic, and then
  instance.disable = False
  # type(instance) = kivy.uix.Button

我将foo与functools.partial绑定.

正确的参数是什么?

推荐答案

如果您使用的是kivy版本> = 1.8，则只需执行widget.disabled = True.如果在以前的版本中您可以自行管理禁用，则只需确保它不会对触摸产生反应，并在禁用时显示其他外观即可.

If you are using kivy version >= 1.8 then you can just do widget.disabled = True. If on previous versions you can simply manage the disabling yourself, just make sure it doesn't react to touch and displays a alternative look when disabled.
