问题描述

我想创建一个表单，用户可以用鼠标将控件（pictureBox）从一侧拖动到另一侧...

在此先感谢...

Hi,
I want to create a form on which user can drag the control(pictureBox)from one side to another side with the mouse...
I searched but I couldn't find the solution...
My problem is how can I get the mouse position(X & Y)on the form(when the mouse is on the control)???

Thanks in Advance...

推荐答案

然后你真的没有那么努力。我真的很讨厌自我推销，但在这里：创建自己的运行时可移动的Windows窗体控件 [ ^ ]

Then you really didn't search that hard. I really hate self-promotion, but here: Create your Own Runtime Movable Windows Forms Controls[^]

#region在运行时移动图片

private void pictureBox1_MouseDown（object sender，MouseEventArgs e）

{

isDragging = true;



currentX = eX;

currentY = eY;

}



private void pictureBox1_MouseMove（object sender，MouseEventArgs e）

{

if（isDragging）

{

pictureBox1.Top = pictureBox1.Top +（eY - currentY）;

pictureBox1.Left = pictureBox1 .Left +（ eX - currentX）;

}

}



private void pictureBox1_MouseUp（object sender，MouseEventArgs e）

{

isDragging = false;

}

#endregion

#region move picture at runtime
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
isDragging = true;

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

private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
{
if (isDragging)
{
pictureBox1.Top = pictureBox1.Top + (e.Y - currentY);
pictureBox1.Left = pictureBox1.Left + (e.X - currentX);
}
}

private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
{
isDragging = false;
}
#endregion
