报错 Gtk-Message: 16:39:00.878: GtkDialog mapped without a transient parent. This is discouraged.

这是一个警告信息,表示在没有设置父窗口的情况下,打开了一个对话框窗口。虽然这不会影响程序的正常运行,但这样做是不鼓励的,因为这可能会导致一些视觉和交互问题。
为了避免这个问题,你可以在打开对话框窗口时设置一个父窗口。例如,如果你使用 GtkBuilder 创建窗口和对话框,可以使用以下代码在打开对话框窗口时设置父窗口:
```python
builder = Gtk.Builder()
builder.add_from_file("my_window.glade")
window = builder.get_object("my_window")
dialog = builder.get_object("my_dialog")
# 设置父窗口
dialog.set_transient_for(window)
# 显示对话框窗口
response = dialog.run()
```
这样就可以避免显示这个警告信息了。

ubuntu GtkDialog mapped without a transient parent. This is discouraged.
As an AI language model, I cannot access the context or information related to your system, so I will provide you with a general answer.
The error message "GtkDialog mapped without a transient parent. This is discouraged" typically occurs when a GtkDialog is created without a parent window or the parent window is not set before the dialog is displayed. A GtkDialog is a modal dialog box that requires a parent window to be displayed correctly.
To fix this error, make sure you set the parent window using the `gtk_window_set_transient_for()` function before displaying the dialog. This ensures that the dialog is properly associated with the parent window and can be displayed correctly.
Here is an example code snippet:
```
// create the parent window
GtkWidget *parent_window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
// create the dialog
GtkWidget *dialog = gtk_dialog_new();
// set the parent window for the dialog
gtk_window_set_transient_for(GTK_WINDOW(dialog), GTK_WINDOW(parent_window));
// display the dialog
gtk_dialog_run(GTK_DIALOG(dialog));
```
By setting the parent window for the dialog, you should no longer receive the "GtkDialog mapped without a transient parent. This is discouraged" error.

这个警告信息是 GTK 程序开发中常见的问题之一,它表示一个 dialog 窗口被创建时没有指定一个父窗口,这样会让程序的用户体验变差。因为如果没有指定父窗口,dialog 窗口可能会被遮挡,或者在任务栏中不易察觉。你可以通过为 dialog 指定一个父窗口来解决这个问题,例如:
```python
dialog.set_transient_for(parent_window)
```
其中 `parent_window` 是 dialog 的父窗口。如果你没有可用的父窗口,也可以使用主窗口作为 dialog 的父窗口,例如:
```python
dialog.set_transient_for(self.get_toplevel())
```
这样可以让 dialog 窗口始终显示在主窗口的上方。
