dialog.showMessageBox 不返回电子 main.js 中的按钮索引

dialog.showMessageBox not returning button index in electron main.js(dialog.showMessageBox 不返回电子 main.js 中的按钮索引)

问题描述

我有一个消息框，当用户单击dashboardWindow 上的关闭时会打开一个消息框(Windows 操作系统右上角的X 按钮)

I have a messagebox that will open when the user click close on dashboardWindow (X button top right on windows os)

dashboardWindow.on("close", (event) => {
    event.preventDefault();
    console.log("before message box");
    dialog.showMessageBox(
      dashboardWindows,
      {
        message: "Test",
        buttons: ["Default Button", "Cancel Button"],
        defaultId: 0, // bound to buttons array
        cancelId: 1 // bound to buttons array
      },
      (response) => {
        if (response === 0) {
          // bound to buttons array
          console.log("Default button clicked.");
        } else if (response === 1) {
          // bound to buttons array
          console.log("Cancel button clicked.");
        }
      }
    );
    console.log("after message box");
  });
}

当我关闭 dashboardWindow 时消息框打开，但我无法让 response === 0 工作.即使没有点击按钮，console.log("after message box"); 也已经运行.我怎样才能做出响应(messageBox 上的返回索引按钮)?

The messagebox opened when i close the dashboardWindow but i can't get response === 0 to work. Samehow console.log("after message box"); already run even when there is no click on the buttons. How I can make the response work (return index button on messageBox)?

请参考最新的 API 文档关于 dialog.showMessageBox:此方法返回一个 Promise 对象并且不再使用回调函数，就像在 Electron v5.xx 之前一样

Please refer to the most recent API doc about dialog.showMessageBox: this method returns a Promise object and doesn't make use of a callback function any more, like it used to until Electron v5.x.x.

Returns Promise
