C# 工具提示中的富文本

发布于 2024-11-16 19:09:47 字数 1130 浏览 2 评论 0原文

我可以扩展 ToolTip 并创建自己的 RichToolTip，但我不明白如何处理每行或每字的格式。我可以添加用户可以单击的控件吗？或图像等。

我遇到了 RichTextBox 但这是用 C++ (MFC) 编写的&我想要 C# 的东西或者可以与 C# 一起使用的东西。有什么建议吗？有没有我可以使用的开源组件？

 public class RichToolTip : ToolTip
    {
    public RichToolTip()
    {
        this.OwnerDraw = true;
        this.Draw += new DrawToolTipEventHandler(OnDraw);
    }

    public RichToolTip(System.ComponentModel.IContainer Cont)
    {
        this.OwnerDraw = true;
        this.Draw += new DrawToolTipEventHandler(OnDraw);
    }
    private void OnDraw(object sender, DrawToolTipEventArgs e)
    {
        DrawToolTipEventArgs newArgs = new DrawToolTipEventArgs(e.Graphics,
                        e.AssociatedWindow, e.AssociatedControl, e.Bounds, e.ToolTipText.Substring(0, 5),
                        this.BackColor, this.ForeColor, new Font("Arial Unicode MS", 8.25f, FontStyle.Bold));
        newArgs.DrawBackground();
        newArgs.DrawBorder();
        newArgs.DrawText(TextFormatFlags.TextBoxControl);
    }
}

I can extend the ToolTip and create my own RichToolTip but I don't understand how I can handle formatting per line or Per word. Can I add controls which a user can click on ? or images etc.

I came across RichTextBox but this is written in C++ (MFC) & I want something for C# or something which I can use with C#. Any suggestions? Are there any open source components which I can use?

 public class RichToolTip : ToolTip
    {
    public RichToolTip()
    {
        this.OwnerDraw = true;
        this.Draw += new DrawToolTipEventHandler(OnDraw);
    }

    public RichToolTip(System.ComponentModel.IContainer Cont)
    {
        this.OwnerDraw = true;
        this.Draw += new DrawToolTipEventHandler(OnDraw);
    }
    private void OnDraw(object sender, DrawToolTipEventArgs e)
    {
        DrawToolTipEventArgs newArgs = new DrawToolTipEventArgs(e.Graphics,
                        e.AssociatedWindow, e.AssociatedControl, e.Bounds, e.ToolTipText.Substring(0, 5),
                        this.BackColor, this.ForeColor, new Font("Arial Unicode MS", 8.25f, FontStyle.Bold));
        newArgs.DrawBackground();
        newArgs.DrawBorder();
        newArgs.DrawText(TextFormatFlags.TextBoxControl);
    }
}
