Docking widgets in gtkmm

[64bit mailme dk]

Hi all,

We are currently porting a project into Gtk from Qt. But Gtk seems to have
some loose ends within some areas. Herein we think the QtDockWidget-like
component is missing in Gtk.

I was earlier recommended the HandleBox, but if we're right, the widget
cannot be relocated in runtime to left/right/top if it's placed in the
bottom of another widget. And this is needed.

Gimp actually has dockable widgets, which has nice functionality to put
multiple dockable widgets into tabs.
Since Gtk and Gimp are associated a lot, it's kinda surprising that this
is not to find in Gtk, or have we overlooked this feature?

During the "research" some people state, that gdl (Gnome Devtool Library)
is the library used by Anjuta and several other projects which all have
this functionality. But the problem is - there is no C++ bindings for this
- or are we wrong? How to use this library along with gtkmm?


Best regards,

Preben
