GTKMM - `WIDGET_REALIZED_FOR_EVENT（小部件，事件）'

我们正在开发 gtkmm24 应用程序。有一个长期存在的错误，如果用户在 Gtk::TreeView 中的 Gtk::CellRendererCombo 上单击得太快，则整个应用程序将因 GTK 断言而锁定：

Gtk-CRITICAL **: IA__gtk_widget_event: assertion `WIDGET_REALIZED_FOR_EVENT (widget, event)' failed

如果您将鼠标悬停在应用程序上的任何位置，则该断言会重复。

在屏幕上，您会看到一个灰色框，其中渲染器组合应该“弹出”：

我的想法是该错误是由于在前一个选择试图完成渲染时选择另一行的组合渲染器而引起的。我尝试了各种延迟和阻止，以不允许用户在上一个选择被“编辑”或“取消”之前选择另一行，但无济于事。

有人有什么想法吗？

We are working on a gtkmm24 application. There's a long standing bug that if a user clicks too quickly on a Gtk::CellRendererCombo in a Gtk::TreeView the whole application locks up with a GTK Assert:

Gtk-CRITICAL **: IA__gtk_widget_event: assertion `WIDGET_REALIZED_FOR_EVENT (widget, event)' failed

This assert then repeats if you mouse anywhere over the application.

On the screen you get a gray box where the renderer combo should have "popped up":

enter image description here

My thought was that the error is caused by selecting another row's combo renderer while a previous selection was trying to finish rendering. I've attempted all sorts of delays and blocks to not allow the user to select another row before the previous selection was "edited" or "canceled" but to no avail.

Anyone got any ideas?
