用deepin用久了，觉得任务栏有优化空间。我就拿 deepseek4 做了优化，目前就这样：

相比官方dde-shell，我做了几个优化：、

• 任务栏右键菜单新增“系统监视器”和“显示桌面”选项

• 时间显示秒针

• 通知中心托盘右键菜单新增"清除所有消息"选项

怎么做到的？ 且听我详细道来———

---

一、任务栏右键菜单新增“系统监视器”和“显示桌面”选项

拉取dde-shell源码：git clone https://github.com/linuxdeepin/dde-shell

-> 找到并打开panels/dock/dockpanel.h，转到第 84-85 行声明 openSystemMonitor() 和 toggleShowDesktop() ：

     Q_INVOKABLE void openDockSettings();
+    Q_INVOKABLE void openSystemMonitor();
+    Q_INVOKABLE void toggleShowDesktop();

-> 找到并打开panels/dock/dockpanel.cpp，转到第 380-400 行补充下列代码 ↓

void DockPanel::openSystemMonitor()
{
    qCDebug(dockLog) << "openSystemMonitor";
    auto *activation = new ds::XdgActivation(this);
    connect(activation, &ds::XdgActivation::tokenReady, this, [activation](const QString &token) {
        QStringList args = {"--by-user", "deepin-system-monitor"};
        if (!token.isEmpty()) {
            qCDebug(dockLog) << "Passing XDG_ACTIVATION_TOKEN to dde-am";
            args << "-e" << QStringLiteral("XDG_ACTIVATION_TOKEN=") + token;
        }
        QProcess::startDetached("dde-am", args);
        activation->deleteLater();
    });
    activation->requestToken();
}

void DockPanel::toggleShowDesktop()
{
    qCDebug(dockLog) << "toggleShowDesktop";
    QProcess::startDetached("/usr/lib/deepin-daemon/desktop-toggle", QStringList());
}

-> 找到并打开panels/dock/dockpanel.cpp，转到第 375-392 行补上qml：

             LP.MenuItem {
                 text: qsTr("Lock the Dock")
                 checked: Panel.locked
                 onTriggered: {
                     Panel.locked = !Panel.locked
                 }
             }
+            LP.MenuItem {
+                text: qsTr("System Monitor")
+                onTriggered: {
+                    Panel.openSystemMonitor()
+                }
+            }
+            LP.MenuItem {
+                text: qsTr("Show Desktop")
+                onTriggered: {
+                    Panel.toggleShowDesktop()
+                }
+            }
             LP.MenuItem {
                 text: qsTr("Dock Settings")
                 ...
             }

新增内容默认英文，需要在panels/dock/translations/org.deepin.ds.dock_zh_CN.ts补上汉化：

    
        Lock the Dock
        禁用自由调节
    
+    
+        System Monitor
+        系统监视器
+    
+    
+        Show Desktop
+        显示桌面
+    

保存、生成deb包、安装即可。

二、时间显示秒针

dde-shell的时间显示由dock插件的libdatetime.so管理，想要修改，把dde-tray-loader源码拉下来修改即可。

拉取dde-tray-loader源码：https://github.com/linuxdeepin/dde-tray-loader

找到并打开plugins/dde-dock/datetime/datetimewidget.cpp，在第120 行和第135 行都加ss：

-        m_timeLabel->setText(timeStr);
+        m_timeLabel->setText(timeStr + current.toString(":ss"));

保存即可。

三、通知中心托盘右键菜单新增"清除所有消息"选项

先进入dde-tray-loader目录

找到并打开plugins/dde-dock/notification/notification.h，加上定义：

     bool dndMode() const;
     void setDndMode(bool dnd);
+    void clearRecords();
     uint notificationCount() const;
 
     void watchNotification(bool newNotification);

找到并打开plugins/dde-dock/notification/notification.cpp，补上以下代码 ↓

     if (m_dbus) {
         m_dbus->call(QLatin1String("SetSystemInfo"), QVariant::fromValue(0u), QVariant::fromValue(QDBusVariant(dnd)));
     }
+}
+
+void Notification::clearRecords()
+{
+    if (m_dbus) {
+        m_dbus->call(QLatin1String("ClearRecords"));
+    }
+    m_notificationCount = 0;
+    m_hasNewNotification = false;
+    Q_EMIT notificationCountChanged(0);
+    Q_EMIT notificationStatusChanged();
 }
 
 uint Notification::notificationCount() const

找到并打开plugins/dde-dock/notification/notificationplugin.cpp，加上定义和有关代码：

         QStringList args {"--by-user", "org.deepin.dde.control-center", "--", "-p", "notification"};
         QProcess::startDetached("dde-am", args);

默认文本是英文，需要在plugins/dde-dock/translations/dde-dock_zh_CN.ts的第413行补上汉化：

         Notification
         通知
     
+    
+        Clear all notifications
+        清除所有消息
+    
 
 
     OnboardPlugin

接着进入dde-shell目录

找到并打开panels/notification/server/dbusadaptor.h，加上代码：

     void SetSystemInfo(uint configItem, const QDBusVariant &value);
     QDBusVariant GetSystemInfo(uint configItem);
 
+    void ClearRecords();
+
 private:
     NotificationManager *manager() const;

找到并打开panels/notification/server/dbusadaptor.cpp，加上代码：

 QDBusVariant DDENotificationDbusAdaptor::GetSystemInfo(uint configItem)
 {
     return QDBusVariant(manager()->GetSystemInfo(configItem));
 }
+
+void DDENotificationDbusAdaptor::ClearRecords()
+{
+    qInfo(notifyLog) << "ClearRecords";
+    manager()->removeNotifications();
+}
 
 } // notification

全部保存、生成deb包、安装即可。

去掉*-dev、* -dbgsym包后，使用apt一股脑安装剩下的包：sudo apt install ./*.deb -y

不要一个个装！会报缺依赖的错误

安装后，重启dde-shell即可：systemctl restart --user dde-shell@DDE.service
