我试图写这样的暗房一个简单的文本编辑器，只是一个RichTextBox（或者一个TextBox）在里面。我的问题是，我不能使用鼠标滚轮的滚动，除非我有一个垂直滚动条。有什么办法来隐藏这个滚动条，仍然能够滚动鼠标滚轮？

I'm trying to write a simple text editor like DarkRoom with just a RichTextBox (or alternatively a TextBox) in it. My problem is that I can't use the mouse wheel for scrolling unless I have a vertical scrollbar. Is there any way to hide this scrollbar and still be able to scroll with the mouse wheel?

到目前为止，我有几个想法怎么可以这样做，但不知道如何实现它们。

So far I have several ideas how this could be done, but no idea how to implement them.

使用鼠标滚轮事件重新创建滚动code 改变滚动条的视觉风格，以隐藏它或使其不太明显 在写我自己的TextBox控件 在重叠用别的东西来隐藏他们的滚动条 re-create the scrolling code using a MouseWheel event change the visual style of the scrollbar to hide it or make it less visible write my own TextBox widget overlap the scrollbars with something else to hide them

PS：使用任意的Win32的东西是不是一种选择

P.S.: Using any win32 stuff is not an option.

推荐答案

是的，你必须捕捉.MouseWheel和.MouseMove事件。请参阅这个帖子。

Yes, you will have to capture the .MouseWheel and .MouseMove events. See this post.

好了，像做以下操作：

添加一行形式加载事件。

Add a line in form load event.

private void Form1_Load(object sender, EventArgs e)
{
    this.richTextBox1.MouseWheel += new MouseEventHandler(richTextBox1_MouseWheel);
}

添加鼠标滚轮事件以下。

Add following in mouse wheel event.

void richTextBox1_MouseWheel(object sender, MouseEventArgs e)
{
    if (e.Delta > 0)
    {
        //Handle mouse move upwards
        if (richTextBox1.SelectionStart > 10)
        {
            richTextBox1.SelectionStart -= 10;
            richTextBox1.ScrollToCaret();
        }
    }
    else
    {
        //Mouse move downwards.
        richTextBox1.SelectionStart += 10;
        richTextBox1.ScrollToCaret();
    }
}

让我知道，在这两种情况下，如果你想的一样运行样本;或者，如果你不喜欢的解决方案（0：
