<p>使用TreeView的 AdvancedCustomDrawItem 方法,</p>
<p>procedure TfrmMain.TreeView1AdvancedCustomDrawItem(Sender: TCustomTreeView;
Node: TTreeNode; State: TCustomDrawState; Stage: TCustomDrawStage; var PaintImages,
DefaultDraw: Boolean); <br>
var NodeRect: TRect; <br>
begin <br>
if Stage = cdPostPaint then begin <br>
if Node.HasChildren then begin <br>
NodeRect := Node.DisplayRect(True); <br>
TreeView1.Canvas.Font.Assign(TreeView1.Font); <br>
TreeView1.Canvas.Font.Color := clBlue; <br>
TreeView1.Canvas.Brush.Style := bsClear; <br>
TreeView1.Canvas.TextOut(NodeRect.Right, NodeRect.Top + 2, '('+InttoStr(Node.Count)+')');
<br>
end; <br>
end; <br>
end; </p>
<p>可以得到图一的效果，可我想统计所有父类包含的所有子列的个数，及得到图二的结果，</p>
<p>不知道如何做！</p>
<p>谢谢！</p>
