请问gtkmm中treeview如何添加事件。
请问gtkmm中treeview如何添加事件。我从数据库中读取数据：
while(没有读完)
{
.........
向treeview中添加数据。
想在这里给treeView添加事件 事件起因是 select_row。(gtk下是这个)
我就是想在单击某一行数据时 打出个新窗口，并把 这一行的数据 如： 1 张三 男 河北 传给打开的窗口。
.........
} 我从数据库中读取数据：
for(int i=0;i<rs_main.GetRecordCount();++i)
{
Gtk::TreeModel::Row row = *(refTreeModel_guest_room->append());
row = rs_main;
row = rs_main;
row = rs_main;
row = rs_main;
row = rs_main;
}
我的大概意思 就是 单击 第一行数据然后 弹出个 新窗口 ，在新窗口要用到此行的数据
