Hi,
I'm pretty new to GUI programming using the gtkmm library and mainly focusing on some new Widgets introduced in the version 3.12. Creating applications that make basic use of the HeaderBar, ActionBar and SearchBar widgets is no problem at the moment, but I'd like to able to design a interface that looks like the ones used by GNOME Clocks, Boxes or others.
Basically I want to allow the user to select items in a window that way:

https://dl.dropboxusercontent.com/u/.../selection.png
I've already tried to understand the source files of both applications but sadly failed due to my missing Vala knowlede. The example source codes in the documentation examples book don't cover any selection in combination with HeaderBars and ActionBars.
Could someone please give me a hint how this is implemented the right way?
Thanks in advance!
