如何链接一组切换按钮，如单选按钮?
问题描述
我正在使用 Python 3 和 Gtk 的 gobject 自省.我怎样才能将多个切换按钮链接在一起，以便它们的行为类似于选项卡或单选按钮 - 例如默认选择一个，当另一个被 clicked 时，之前的 active 一个被取消选择.
I am using Python 3 with gobject introspection for Gtk. How can I have more than one toggle button linked together so they behave similar to tabs or radiobuttons - e.g. one is selected by default, and when another is clicked the previously active one is de-selected.
我曾尝试使用 set_sensetive，但它应用的小部件会变灰.
I have tried using set_sensetive, but that greys out the widget that it is applied on.
解决方案
使用 set_active()(或 props.active).或者，您可以创建一些 Gtk.RadioButton 小部件并将 draw_indicator 属性设置为 False.在后一种情况下，您可以以正常方式创建单选组，无需自定义处理.
Use set_active() (or props.active). Alternatively, you can create some Gtk.RadioButton widgets and set draw_indicator property to False. In the latter case you can create radio groups in normal way, without custom handling.
