Treenode文字不同的彩色字 [英] Treenode text different colored words

问题描述

我有一个 TreeView ，它的每个 Node.Text 有两个单词。
第一个和第二个单词应该有不同的颜色。我已经改变文本的颜色与 DrawMode 属性和 DrawNode 事件，但我不能如何用两种不同的颜色分割 Node.Text 。有人指出我可以使用 TextRenderer.MeasureText 但我没有idead如何/在哪里使用它。

I have a TreeView and each of it's Node.Text has two words. The first and second words should have different colors. I'm already changing the color of the text with the DrawMode properties and the DrawNode event but I can't figure out how to split the Node.Text in two different colors. Someone pointed out I could use TextRenderer.MeasureText but I have no idead how/where to use it.

有人有想法吗？

代码： b

formload()
{
  treeView1.DrawMode = TreeViewDrawMode.OwnerDrawText;
}

private void treeView1_DrawNode(object sender, DrawTreeNodeEventArgs e) 
{
Color nodeColor = Color.Red;
if ((e.State & TreeNodeStates.Selected) != 0)
  nodeColor = SystemColors.HighlightText;

 TextRenderer.DrawText(e.Graphics,
                    e.Node.Text,
                    e.Node.NodeFont,
                    e.Bounds,
                    nodeColor,
                    Color.Empty,
                    TextFormatFlags.VerticalCenter);
}

Try this:

    private void treeView1_DrawNode(object sender, DrawTreeNodeEventArgs e)
    {
        string[] texts = e.Node.Text.Split();
        using (Font font = new Font(this.Font, FontStyle.Regular))
        {
            using (Brush brush = new SolidBrush(Color.Red))
            {
                e.Graphics.DrawString(texts[0], font, brush, e.Bounds.Left, e.Bounds.Top);
            }

            using (Brush brush = new SolidBrush(Color.Blue))
            {
                SizeF s = e.Graphics.MeasureString(texts[0], font);
                e.Graphics.DrawString(texts[1], font, brush, e.Bounds.Left + (int)s.Width, e.Bounds.Top);
            }
        }
    }

您必须管理 State 的节点执行适当的操作。

You must manage State of node to do appropriated actions.

UPDATE

对不起，我的错误看到更新版本。没有必要测量空间大小，因为它已经包含在 texts [0] 。

Sorry, my mistake see updated version. There is no necessary to measure space size because it already contains in texts[0].
