GtkAboutDialog关闭按钮错误 [英] GtkAboutDialog Close Button Bug

问题描述

我使用GtkAboutDialog，除了这个小部件的关闭按钮外，一切正常。所有其他按钮工作正常，我不知道如何，但所有按钮都有默认回调，他们创建和销毁窗口。
但是GtkAboutDialog小部件的关闭按钮不起作用。我什至不能看到它的小部件。所以，我可以访问它吗？

[CLARIFICATION]你正在看的是gtk.AboutDialog - 弹出窗口显示应用程序的相关信息（PyGTK 2.6中的新增功能）。此窗口包含GtkHButtonBox小部件中包含的'close'按钮小部件。 GtkHButtonBox小部件是我能够访问的最高级别小部件。任何有关如何进入关闭按钮并连接处理程序以获取回调信号的想法？

解决方案

像对待窗口一样进行对话。学习PyGTK时犯了同样的错误。

对话框的最基本形式是显示并运行对话框：

  aboutdialog.run（）
  

然后立即调用：

  aboutdialog.destroy（）
  

.run（）行是一个循环，它会一直运行，直到在对话框中发生某种事情。

在这里示例。

I use GtkAboutDialog and everything works fine except the close button of this widget. All other buttons works fine, I don't know how but all buttons have default callbacks and they create and destroy the windows. But the "Close" button of GtkAboutDialog widget does not work. I can not even see it's widget. So, can I access it?

[CLARIFICATION] What you're looking at is gtk.AboutDialog — popup window displaying information about an application (new in PyGTK 2.6). This window contains the 'close' button widget which is contained in a GtkHButtonBox widget. The GtkHButtonBox widget is the highest level widget I am able to access for some. Any ideas on how to get to the "close" button and connect a handler for a callback signal?

解决方案

You don't conenct signals in the same way for a dialog as you do for a window. I made the same mistake when learning PyGTK.

The most basic form of a dialog is you display and run the dialog with:

aboutdialog.run()

Often you will then immediately call:

aboutdialog.destroy()

The .run() line is a loop, which runs until something happens within the dialog.

There is a working example here.
