如何在标签箱内移动标签 [英] how do I make label moveable inside picturebox

问题描述

大家好，



我写这段代码来移动label1，我创建int x和y来取得label1的新位置，它正常工作。

我的问题是我创建了图片框，我将label1放在图片框的左上角位置，我希望label1在图片框内移动而不是在图片的任何地方。

  private   void  label1_MouseDown（< span class =code-keyword> object  sender，MouseEventArgs e）
 {
  if （e.Button == MouseButtons .Left）
 {
 _Offset =  new  Point（eX，eY）; 
} 
} 
 
  private   void  label1_MouseUp（  object  sender，MouseEventArgs e）
 {
 _Offset = Point.Empty; 
} 
 
  private   void  label1_MouseMove（ object  sender，MouseEventArgs e）
 {
  if （_ Offset！= Point.Empty）
 {
 Point newlocation = label1.Location; 
 newlocation.X + = e.X  -  _Offset.X; 
 newlocation.Y + = e.Y  -  _Offset.Y; 
 label1.Location = newlocation; 
 
 x = newlocation.X; 
 y = newlocation.Y; 
} 
 label3.Text = x.ToString（）; 
 label4.Text = y.ToString（）; 
} 

关心所有。

解决方案

你完全错了。



我写了一篇关于这几年前的文章。 创建自己的运行时可移动Windows窗体控件 [< a href =http://www.codeproject.com/Articles/14770/Create-your-Own-Runtime-Movable-Windows-Forms-Conttarget =_ blanktitle =New Window> ^

Hi all,

I write this code to move the label1 and i create int x and y to take the new position of the label1 and it works correctly.
My problem that I create picturebox and I place label1 in the top left position inside the picturebox and I want label1 to move just inside the picturebox not in anywhere in the form.

private void label1_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                _Offset = new Point(e.X, e.Y);
            }
        }

        private void label1_MouseUp(object sender, MouseEventArgs e)
        {
            _Offset = Point.Empty;
        }

        private void label1_MouseMove(object sender, MouseEventArgs e)
        {
            if (_Offset != Point.Empty)
            {
                Point newlocation = label1.Location;
                newlocation.X += e.X - _Offset.X;
                newlocation.Y += e.Y - _Offset.Y;
                label1.Location = newlocation;

                x = newlocation.X;
                y = newlocation.Y;
            }
            label3.Text = x.ToString();
            label4.Text = y.ToString();
        }

Regards all.

You're doing it entirely wrong.

I wrote an article on doing exactly this years ago. Create your Own Runtime Movable Windows Forms Controls[^]
