在运行时在 winform 内拖动图片框 [英] dragging picturebox inside winform on runtime

问题描述

我需要能够在 vb.net 中将带有图像的图片框拖放到我的 winform 周围.

i need to be able to drag and drop my picturebox with an image in it around my winform in vb.net.

推荐答案

这是在 C# 中，但应该很容易在 VB.Net 中复制.

This is in C#, but should be easy enough to replicate in VB.Net.

private int   currentX, currentY;
private bool  isDragging = false;

private void myPictureBox_MouseDown(object sender, MouseEventArgs e) 
{
  isDragging = true;

  currentX = e.X;
  currentY = e.Y;
}

private void myPictureBox_MouseMove(object sender, MouseEventArgs e) 
{
  if (isDragging) 
  {
    myPictureBox.Top = myPictureBox.Top + (e.Y - currentY);
    myPictureBox.Left = myPictureBox.Left + (e.X - currentX);
  }
}

private void myPictureBox_MouseUp(object sender, MouseEventArgs e) 
{
  isDragging = false;
}
