详情见《小hack一下gnome-shell的alt+tab》and《GNOME Shell的“Alt＋Tab”革新》

听从TualatriX建议写成了个扩展

这可是我第一个gnome-shell扩展哦

刚开始看js 也刚耍上gnome-shell

用的也是最笨的方法………………

使用方法：

在~/.local/share/gnome-shell/extensions/建立alt_tab_key_press@imdiot.wordpress.com文件夹

在alt_tab_key_press@imdiot.wordpress.com文件夹中建立两文件

extension.js:

 1 const St = imports.gi.St;
 2 const Mainloop = imports.mainloop;
 3 const Shell = imports.gi.Shell;
 4 const Clutter = imports.gi.Clutter;
 5 const Meta = imports.gi.Meta;
 6 const Lang = imports.lang;
 7 
 8 const Main = imports.ui.main;
 9 const AltTab = imports.ui.altTab;
10 
11 function startAppSwitcher (shellwm, binding, window, backwards) {
12     if (shellwm._workspaceSwitcherPopup != null)
13         shellwm._workspaceSwitcherPopup.actor.hide();
14 
15     let tabPopup = new AltTab.AltTabPopup();
16     tabPopup._keyPressEvent = function(actor, event) {
17         let keysym = event.get_key_symbol();
18         let event_state = Shell.get_event_state(event);
19         let backwards = event_state & Clutter.ModifierType.SHIFT_MASK;
20         let action = global.screen.get_display().get_keybinding_action(event.get_key_code(), event_state);
21 
22         this._disableHover();
23 
24         if (action == Meta.KeyBindingAction.SWITCH_GROUP)
25             this._select(this._currentApp, backwards ? this._previousWindow() : this._nextWindow());
26         else if (keysym == Clutter.Escape)
27             this.destroy();
28         else if (this._thumbnailsFocused) {
29             if (action == Meta.KeyBindingAction.SWITCH_WINDOWS)
30                 if (backwards) {
31                     if (this._currentWindow == 0 || this._currentWindow == -1)
32                         this._select(this._previousApp());

35                 } else {
36                     if (this._currentWindow == this._appIcons[this._currentApp].cachedWindows.length - 1)
37                         this._select(this._nextApp());
38                     else
39                         this._select(this._currentApp, this._nextWindow());
40                 }
41             else if (keysym == Clutter.Left || keysym == Clutter.a)
42                 this._select(this._currentApp, this._previousWindow());

47         } else {

49                 this._select(backwards ? this._previousApp() : this._nextApp());
50             else if (keysym == Clutter.Left || keysym == Clutter.a)
51                 this._select(this._previousApp());
