如何在GTK + 3中处理键盘事件？(How do I handle keyboard events in GTK+3?)

我应该用什么信号/功能在GTK + 3中输入键盘？

我环顾四周，我所知道的唯一涵盖GTK + 3（ zetcode和gnome开发人员 ）的教程似乎并没有涵盖这一点。

任何人都可以指出我正确的方向？

What signals/functions should I use to get keyboard input in GTK+3?

I have looked around and the only tutorials I know of that cover GTK+3 (zetcode and gnome developer) don't seem to cover that.

Anyone can point me in the right direction?

谢谢你的建议，这真的很有帮助。 我迷路了，因此我的问题可能过于笼统，无法摆脱C社区部分传统的贬低。 我将在这里总结一下如何在GTK3中处理键盘事件，我希望这会有用，因为我无法在其他任何地方找到它。

想象一下，您正在使用GTK + 3，并且您希望应用程序在按空格键时执行某些操作。 这是你如何做到的：

-First为您的Gdk.Window启用#GDK_KEY_PRESS_MASK掩码：

gtk_widget_add_events(window, GDK_KEY_PRESS_MASK);

- 然后使用keyboard_press（）函数连接窗口：

g_signal_connect (G_OBJECT (window), "keyboard_press", G_CALLBACK (on_key_press), NULL);

- 按下空格键后，将keyboard_press（）定义为某些内容：

gboolean my_keypress_function (GtkWidget *widget, GdkEventKey *event, gpointer data) { if (event->keyval == GDK_KEY_space){ printf("SPACE KEY PRESSED!") return TRUE; } return FALSE; }

Thanks xing for your advice, It was really helpful. I was lost, hence my question that is perhaps too general to escape the traditional downvoting of part of the C community. I will summarize here how to handle keyboard events in GTK3, which I hope will be useful since I cannot find it put together anywhere else.

Imagine you are using GTK+3 and you want your application to do something when you press the space key. This is how you do it:

-First enable the #GDK_KEY_PRESS_MASK mask for your Gdk.Window:

gtk_widget_add_events(window, GDK_KEY_PRESS_MASK);

-Then you connect the window with the keyboard_press() function:

g_signal_connect (G_OBJECT (window), "key_press_event", G_CALLBACK (my_keypress_function), NULL);

-Define your keyboard_press() to something once the space key has been pressed:

gboolean my_keypress_function (GtkWidget *widget, GdkEventKey *event, gpointer data) { if (event->keyval == GDK_KEY_space){ printf("SPACE KEY PRESSED!") return TRUE; } return FALSE; }
