RE: Handling multiple selections in a Gtk::TreeView

["Foster, Gareth" <gareth foster siemens com>]

I think they let you do stuff like this (I'm pretty sure I used them in Java
last year)

class someClass
{
private:
	int data;
public:
	someClass()
	{
		// takes a function as an argument
		doSomeStuff (
					// actually define a function here,
without naming it, I forget the syntax
					{
						++ data;
					}
				);
	}
};

That's about the gist of it I think.

Cheers!

Yes, I think that get_selected_rows() was added sometime after
selected_foreach(), because it was more convenient.

I don't understand the comment about C++ not having anonymous functions.
Maybe that's C# terminology.

Actually, I can't think of a case when it is right now. If you think of
one, let's document it.
