qt - QML 连接 : Implicitly defined onFoo properties in Connections are deprecated

Question

升级到 Qt 5.15 时，我收到以下错误消息:

QML Connections: Implicitly defined onFoo properties in Connections are deprecated.
Use this syntax instead: function onFoo(<arguments>) { ... }

下面贴出对应的QML代码

Connections {
    target: AppProxy

    onLogsReady: function(logs) {
        textLogs.text = logs
    }
}

哪里onLogsReady是 AppProxy 中定义的信号类(class):

class AppProxy : public QObject {
  Q_OBJECT
  Q_DISABLE_COPY(AppProxy)

 public:
  AppProxy(QObject* parent = 0);
  ~AppProxy();

 signals:
  void logsReady(QString logs);

// ...
};

我想知道如何抑制这个警告。

在 Qml 5.15 中有一种新的连接语法。在您的情况下，它看起来像这样:

Connections {
    target: AppProxy

    function onLogsReady(logs) {
        textLogs.text = logs
    }
}
