There was a problem hiding this comment.
Hey - I've found 1 issue, and left some high level feedback:
- The new LauncherHelper class is declared inside the dock namespace, but dockpanel.cpp calls qmlRegisterSingletonType without a namespace qualifier; this likely won’t compile and should use dock::LauncherHelper (or a using declaration) consistently on both the type and the instance() call.
- Each call to MenuHelper.openMenu now does menu.aboutToHide.connect(...) without disconnecting previous connections, so opening the same menu multiple times will accumulate duplicate handlers; consider using a one-shot connection, checking isSignalConnected, or explicitly disconnecting before reconnecting.
- LauncherHelper::hideLauncher() creates a new QDBusInterface on every call; if this is invoked frequently, consider caching the interface as a member or using a helper to avoid repeated construction and validity checks.

**issue:** Consider qualifying LauncherHelper with its namespace in both the template parameter and the factory lambda.
Since `LauncherHelper` lives in the `dock` namespace, please qualify it as `dock::LauncherHelper` in both the `qmlRegisterSingletonType` template parameter and the lambda return to avoid potential name lookup/ODR issues if another `LauncherHelper` is introduced elsewhere.
```cpp
qmlRegisterSingletonType<dock::LauncherHelper>(
"org.deepin.ds.dock.helper", 1, 0, "LauncherHelper",
[](QQmlEngine *, QJSEngine *) -> QObject * {
return dock::LauncherHelper::instance();
});
```
