更改treeview节点颜色

Question

有没有办法改变TTreeView中节点的颜色。我想用深色为树视图着色，然后我看不到节点。

Answer 1

您只想更改线条颜色并不容易。 无论如何，API中有一条消息;

uses
  commctrl;

procedure TForm1.FormCreate(Sender: TObject);
begin
  SendMessage(TreeView1.Handle, TVM_SETLINECOLOR, 0, ColorToRGB(clYellow));
end;

Answer 2

也许你可以使用TTreeView的OnCustomDrawItem事件：

procedure TForm1.TreeView1CustomDrawItem(Sender: TCustomTreeView;
  Node: TTreeNode; State: TCustomDrawState; var DefaultDraw: Boolean);
begin
  with Sender as TCustomTreeView do
  begin
    Canvas.Brush.Color := clBlack;
    Canvas.Font.Color := clBlack
  end;
end;
