有没有办法取消选中组中的所有单选按钮？ （PyGTK的） [英] Is there a way to uncheck all radio buttons in a group? (PyGTK)

问题描述

有没有办法用PyGTK取消选中组中的所有单选按钮？在启动时没有检查单选按钮，所以我认为必须有一种方法将它们全部返回到未检查状态。

不应该有。就其性质而言，单选按钮组是一种挑多种控制类型之一。从人的角度来看，这个想法是，他们中的一个总是被选中。该框架确实应该强制执行，所以对于该组来说实际上不应该是未选定状态。单选按钮组的非选中状态（在可能的框架中）对用户来说非常混乱，因为这不是他们可以控制的状态。

如果你想要一个'没有选择'的状态，我会说你应该给这个组添加一个'none'元素，或者选择一个符合你想要的控制类型。

Is there a way to uncheck all radio buttons in a group with PyGTK? No radio buttons are checked on startup, so I think there must be a way to return them all to that unchecked state.

解决方案

There shouldn't be. By their nature, a radio button group is a 'pick one of many' type of control. From a human perspective, the idea is that one of them is always selected. The framework really should enforce that, so there really shouldn't be a 'none selected' state for the group. The none-selected state of a radio button group (in frameworks where it's possible) is very confusing to users, because that's not a state that they can get the control into.

If you want a 'none selected' state, I'd say you should add a 'none' element to the group, OR chose a different control type that conforms to what you want to do with it.
