你的gnome-shell-extension如何抓住重点？

Question

我有一个BoxLayout，里面有多个演员。其中一位演员是St.Entry。 我希望这个条目具有键盘焦点，所以当创建窗口时，我可以立即开始输入。

我已经找到了＆＃34; grab_key_focus（）＆＃34;方法，但如果我在我的条目上调用它，它什么都不做。

我很感谢你能给我的任何帮助，因为这里有一份非常稀缺的文件......

The trick is

global.stage.set_key_focus(entry);

I found this by reading the source of an existing extension (Project Hamster extension), the exact line is here: https://github.com/projecthamster/shell-extension/blob/c99fb165430d12ff7e6e9b4c5a20f43eb56b810d/extension.js#L149

I use this extension and it has a text entry with initial focus which made me look in this extension for the functionality. How the author of that extension figured it out, I do not know.
