TreeView

["J. Baltasar Garcia Perez-Schofield" <jbgarcia uvigo es>]

	Hi, there !

	I have a TreeView used in order to show some information. However, I
would like the user to have the opportunity to show some columns and
hide others. The TreeModel needs therefore to be dynamic. So I was
creating the famous column layout:

class DocumentColumns : public Gtk::TreeModel::ColumnRecord {
public:
	Gtk::TreeModelColumn<string> data;

	DocumentColumns()
		{}
			
	createColumns();
};

	However, I need to specify the actual number of
Gtk::TreeModelColumn<>'s I need, and I simply don't know they number at
compile time. Would it be possible to create a vector of
Gtk::TreeModelColumn<>'s, and adding that dynamically-created columns ?
Will the TreeView change when the model changes (afer calling
createColumns() and set_model()) ? Or do I have to recreate the TreeView
from the beginning ?

	Actually (this is constructive criticism), I have to confess that I am
very disappointed with TreeView and the absence or CList (or something
like that). I would like to add string columns and rows for simple uses
such as this one in a simple way, and not with the overhead that
TreeView implies, which is good for advanced uses but excessively
complex for the easiest ones.

	I wonder why CList was not re-implemented for Gtkmm2 as a wrapper for
TreeView. Or maybe there is another component doing this which I don't
know about.

	Salud !

		Baltasar
