显示部件Gtk::TreeView,数据管理Gtk::ListSore,每一行的数据Gtk::TreeModel::Row
列要从Gtk::TreeModel::ColumnRecord派生出一个类，在Gtk::ListStore创建时要用，Gtk::TreeView显示时也要用。
可能用到

新建store

static Glib::RefPtr<ListStore> Gtk::ListStore::create ( const TreeModelColumnRecord& columns )

设定TreeModel

void Gtk::TreeView::set_model ( const Glib::RefPtr<TreeModel>& model )

ListStore添加一行

iterator Gtk::ListStore::append ( )

访问

reference Gtk::TreeIter::operator* ( )
//typedef const Gtk::TreeRow& reference
TreeValueProxy<ColumnType> operator[] (const TreeModelColumn<ColumnType>& column) const

TreeView添加列

int Gtk::TreeView::append_column ( TreeViewColumn& column )

也可以是

int Gtk::TreeView::append_column_editable ( const Glib::ustring & title,

const TreeModelColumn<ColumnType>& model_column)

	int Gtk::TreeView::append_column_numeric  	(  	const Glib::ustring &   	 title,
			const TreeModelColumn<ColumnType>&  	model_column,
			const Glib::ustring &  	format)

一个Gtk::TreeModel::ColumnRecord的子类

class columns:public Gtk::TreeModel::ColumnRecord

{

public:

Gtk::TreeModelColumn<int> id;
Gtk::TreeModelColumn<std::string> name;

Gtk::TreeModelColumn<double> g;
columns(){add(id);add(name);add(g);}

};

清除表中以前产生的列

TreeView::remove_all_columns();

访问值

TreeModel::children()
