我知道在 GTK+ 中你可以创建按钮、事件等，但是有没有办法让你在 cairo 中创建的东西（假设你画一个圆圈）成为可点击的按钮？我想我对 GTk 和 cairo 之间的关系感到困惑。

Cairo is a 2D graphic library that provides drawing API, GTK+ uses Cairo to draw itself, for clicking items made with Cairo you might want to have a look at a Canvas such as GooCanvas [1], it supports introspection so you can use it from Python too (pygobject 3) [2]
Items [3] created with GooCanvas support events and are drawn with Cairo underneath, so you can draw a circle [4] and use the events as you prefer.

正如 giamt 所说，你需要一个画布。对于 GTK 2，GooCanvas 可能会有所帮助。对于 GTK 3（甚至可能是 GTK 2），Clutter 可能是首选。
