检测GUI中的特定按键 [英] Detect specific keypresses in GUI

问题描述

我在Gtk / Python中寻找一种方法来让应用程序监听按键，当某些特殊按键被按下时，执行一个操作（重新创建一个带有不同标签的菜单，因为它是一个appindicator）。尽管如此，我还是无法找到办法。如果有人能够提供帮助，我会很感激。 您可能需要处理key-press-event（也可能key-release-event）的GtkWidget。 PyGtk了解 。

它应该位于某个窗口窗口小部件的内部，因此您可能需要使用 GtkEventBox 作为容器。

I'm looking for a way in Gtk/Python to have an app listen for keypresses and when some of the special keys are pressed, perform an action (recreate a menu with different labels, since it's an appindicator). I can't really find a way to do it though. If anyone is able to help, I'd be thankful.

解决方案

You probably need to handle the "key-press-event" (and probably also "key-release-event") of GtkWidget. PyGtk knows about it.

It should be inside some "windowing" widget, so you may need to use GtkEventBox as a container.
