光标后的C#对象...

问题描述

这是我的代码

This is my code

private void You_MouseDown(object sender, MouseEventArgs e)
        {
            You.Location = Cursor.Position;
        }

问题是它不跟随它，picturebox(You)只是去某个随机位置而不跟随光标，任何人都可以帮忙吗?

Mt problem is that its not following it, the picturebox(You) is just going to some random location and not following the cursor, can anyone help?

推荐答案

private void You_MouseDown(object sender, MouseEventArgs e)
{
  You.Location = e.Location;
}

或将光标位置转换为客户坐标的以下解决方案:

or this solution that converts the Cursor position to client coordinates:

private void You_MouseDown(object sender, MouseEventArgs e)
{
  You.Location = PointToClient(Cursor.Position);
}

bool m_bMouseDown = false;

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
  button1.Location = PointToClient(Cursor.Position);
  m_bMouseDown = true;
}

private void Form1_MouseMove(object sender, MouseEventArgs e)
{
  if (m_bMouseDown)
    button1.Location = PointToClient(Cursor.Position);
}

private void Form1_MouseUp(object sender, MouseEventArgs e)
{
  m_bMouseDown = false;
}

private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                PictureBox b = ((PictureBox) sender);
                b.Location = new Point(b.Left + e.X, b.Top + e.Y);

            }
        }
