GtkDialog映射没有临时父项

问题描述

我有一个内置于Glade（3.18）的GUI，它由Python 3程序（使用PyGObject）调用。在运行程序（Fedora 21）时，我收到很多警告：

  Gtk-Message：GtkDialog映射时没有瞬态家长。这是不鼓励的。 
  

如何解决此警告？我尝试在Glade的所有对话框窗口中填写 Transient for：main_window 字段，但警告依然出现。

你通过给GtkDialog一个父对象来解决这个警告。相关函数是 gtk_window_set_transient_for（）（它将此窗口设置为始终位于另一个窗口的顶部，或 transient），另一个可选 gtk_window_set_modal（）使其成为模态对话框。这最终是各种GtkDialog构造函数的作用。

I have a GUI built in Glade (3.18) which is called by a Python 3 program (using PyGObject). I get a lot of warnings when running the program (Fedora 21) that say:

Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

How can I fix this warning? I tried filling in the field Transient for: main_window in Glade for all the dialog windows, but the warnings still appear.

解决方案

You fix this warning by giving the GtkDialog a parent to be modal to. The relevant functions are gtk_window_set_transient_for() (which sets this window to always be on top of, or transient for, another one) and optionally gtk_window_set_modal() to make it a modal dialog. This is ultimately what the various GtkDialog constructors do.
