问题:

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.

I have tried using set_sensetive, but that greys out the widget that it is applied on.

回答1:

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.

回答2:

Use a Gtk.RadioButton and set draw indocator mode to False

button1 = Gtk.RadioButton("Product Codes")
button1.set_mode(False)

How can I link a set of toggle buttons like radio buttons?

回答3:

You listen to the toggle signals on the toggle button then call set_active() on the other ones. You need to block the toggled signals while calling set_active()so that you don't get into a loop.
