在C#中打开GTK窗口，返回数据并关闭窗口，然后打开另一个窗口？

我正在使用C#with GTK编写一个主窗口包含按钮的应用程序。当按下其中一个按钮时，它将调用一个事件处理函数，该函数将打开一个新窗口，其中包含供用户填写的表单。到目前为止，一切都很好

我遇到的问题是，我需要让这个事件处理函数打开这个窗口，等待它被填充并关闭，然后打开第二个窗口，等待它被填充并关闭，然后处理所有捕获的数据。 我已经做了一个简单的例子来说明我的意思（我理解在下面的例子中，打开一个带有两个组合框的窗口会更有意义，但那是因为这只是一个例子！）

上述情况下，两个窗口同时打开，标签立即用默认数据更新，而不是在两个窗口中选择的数据。所以我有两个问题：

1） 如何让它打开WindowOne，等待数据被检索，然后打开WindowII，等待数据被检索，然后更新标签

2） 如何编辑“OnSend”函数，使其在调用SetFavDrink/SetFaveCheese函数后关闭窗口

有人能给我指一下这里的正确方向吗？我对这种编程百灵鸟还不熟悉，所以要温柔

我想这就是你想要的（注意，这可能会被清理掉……）：
