处理GTK +中的按键操作（gtkD）

I'm playing around with gtkD (a D binding for GTK+)

我正在玩gtkD(GTK +的D绑定)

I have a window object, instance of gtk.MainWindow. I want to handle keypresses on it.

我有一个window对象,gtk.MainWindow的实例。我想处理它上面的按键。

• How?
• How do I deal with special keys (e.g. arrow keys, pgup/pgdn etc)?

我如何处理特殊键(例如箭头键,pgup / pgdn等)?

PS I know these kinds of questions can be answered with google and stuff, but I've seen much "simpler" questions on *, so I figured asking doesn't hurt.

PS我知道这些问题可以用谷歌和东西来回答,但我在*上看到了很多“更简单”的问题,所以我觉得问不伤。

Plus, sometimes, basic things tend to be burried under pages of documentation.

此外,有时,基本的东西往往被埋在文档页面下。

Here is sample code which may help

以下是可能有用的示例代码

import gdk.Keysyms; //keys enums are defined here

private void func(Button sender)
{
    //button pressed
}

but.addOnClicked(&func);

private bool func2(GdkEventKey* ev, Widget sender)
{
    if(ev.keyval == GdkKeysyms.GDK_Tab) 
        return true; //we handle Tab ourselves and prevents default behaviour
    else
        return false; //we didnt handle it so gtk does default behaviour
}

win.addOnKeyPress(&func2);
