如何重写拷贝和粘贴的RichTextBox [英] How to override copy and paste in richtextbox

问题描述

我如何可以覆盖一个RichTextBox C＃应用程序的复制/粘贴功能。
包括CTRL-C / CTRL-V并右击复制/粘贴。

How can I override the copy/paste functions in a Richtextbox C# application. Including ctrl-c/ctrl-v and right click copy/paste.

这是WPF的RichTextBox。

It's WPF richtextBox.

推荐答案

要覆盖命令功能：

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) 
{
  if (keyData == (Keys.Control | Keys.C))
  {
    //your implementation
    return true;
  } 
  else if (keyData == (Keys.Control | Keys.V))
  {
    //your implementation
    return true;
  } 
  else 
  {
    return base.ProcessCmdKey(ref msg, keyData);
  }
}

和右键单击不在一个WinForms RichTextBox的支持

And right-clicking is not supported in a Winforms RichTextBox

实现为时已晚，这是一个WPF问题。在WPF做到这一点，你需要附加一个自定义的复制和粘贴处理程序：

Realized too late this was a WPF question. To do this in WPF you will need to attach a custom Copy and Paste handler:

DataObject.AddPastingHandler(myRichTextBox, MyPasteCommand);
DataObject.AddCopyingHandler(myRichTextBox, MyCopyCommand);

private void MyPasteCommand(object sender, DataObjectEventArgs e)
{
    //do stuff
}

private void MyCopyCommand(object sender, DataObjectEventArgs e)
{
    //do stuff
}
