Gtk.TreeView (2)

根據昨天的程式，稍作改良，就可以把整個目錄樹丟進去顯示了…
下面就是利用 Recursive 來把資料塞到 TreeStore 裡面去。

public void _buildTreeStore( TreeStore store, DirectoryInfo di, TreeIter parent )
{
foreach( DirectoryInfo iter in di.GetDirectories() )
{
TreeIter ti = store.AppendValues( parent, iter.FullName, iter.Name, "" );
_buildTreeStore( store, iter, ti, true  );
}
// add files in tree
foreach( FileInfo fi in di.GetFiles() )
store.AppendValues( parent, fi.FullName, fi.Name, fi.Length.ToString() );
}
public TreeStore buildTreeStore( string path )
{
// 0: fullpath 1: name 2: filesize
TreeStore store = new TreeStore( typeof(string), typeof(string), typeof(string) );
DirectoryInfo di = new DirectoryInfo( path );
TreeIter root = store.AppendValues( path, di.Name, "" );
_buildTreeStore( store, di, root );
return store;
}
public ExplorerSharp(): base(Gtk.WindowType.Toplevel)
{
Build();
TreeStore store = buildTreeStore( "./" );
// 設定資料來源
treeview1.Model = store;
// 不顯示表頭
treeview1.HeadersVisible = false;
// 設定要顯示的欄位
treeview1.AppendColumn("Name", new CellRendererText(), "Name", 1 );
treeview1.AppendColumn("Size", new CellRendererText(), "FileSize", 2 );
// 一次只能選定一列或一個節點
treeview1.Selection.Mode = Gtk.SelectionMode.Single;
}
