GTK+ equivalent to QDockWdiget

There is a widget equivalent t开发者_开发知识库o Qt QDockWidget in GTK+? I'm trying to find one on glade-3 but I couldn't find it.

If there isn't, what's the correct way to create a dockable widget?

You might also check out libgdl - although it seems the documentation is sparse at best. This is what Anjuta uses for their dockable components.

I haven't used either one,but based on the descriptions, I think GtkHandleBox is what you want.
