Python 如何多次显示使用Glade定义的对话框？

我想多次显示Glade文件中定义的

Gtk.Dialog

目前，我可以使用自定义按钮调用对话框的

hide（）

方法来完成此操作，但是，如果用户使用Alt+F4关闭对话框，它将重新打开为空：

在控制台中，我看到多个错误：

我正在使用一个普通的

get\u object（）

获取对话框的实例：

而不仅仅是调用

show（）

和

hide（）

。但是在使用Alt+F4关闭它之后，我无法再次显示它。

由于，我发现您必须连接到对话框的

删除事件

，并确保返回

True

，以避免对话框被破坏

首先在Glade中创建信号处理程序，然后在Python代码中：

def on_dialog_delete_event(self, dialog, event):
    dialog.hide()
    return True 

---

这正是我们所做的。只需将窗口的

delete事件

连接到它，无需创建自己的回调。我正在从Glade连接我的回调，是否可以从Glade直接连接

hide_on_delete

？

def on_dialog_delete_event(self, dialog, event):
    dialog.hide()
    return True
