Winform 空间位置及大小自适应

文章参考:http://blog.csdn.net/loveme1204/archive/2007/12/24/1964577.aspx

是一篇vb编写的,我只是把它翻译成c#的.

其实Anchor和Dock属性也可以实现,但好象只对容器效果理想,而且字体大小也没有变化.最近论坛上有好多这样的贴子,具体实现代码如下:

 private void  setTag(Control cons)
 {
     foreach (Control con in cons.Controls)
     {
         con.Tag = con.Width +":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;
         if (con.Controls.Count > 0)
             setTag(con);
     }
 }
 private void setControls(float   newx, float  newy, Control  cons)
 {
     foreach (Control  con in cons .Controls )
     {

         string[] mytag = con.Tag.ToString().Split(new char[] { ':' });
         float a = Convert.ToSingle(mytag[0]) * newx;
         con.Width = (int)a;
         a=Convert.ToSingle(mytag[1]) * newy;
         con.Height = (int)(a);
         a=Convert.ToSingle(mytag[2]) * newx;
         con.Left = (int)(a);
         a=Convert.ToSingle(mytag[3]) * newy;
         con.Top = (int)(a);
         Single currentSize = Convert.ToSingle (mytag[4]) * newy;
         con .Font =new Font (con.Font .Name ,currentSize,con.Font .Style ,con.Font .Unit );
         if(con.Controls .Count >0)
         {
             setControls (newx ,newy ,con );
         }
     }

 }

 void Form1_Resize(object sender, EventArgs e)
 {
    // throw new Exception("The method or operation is not implemented.");
     float  newx = (this.Width )/ X;
   //  float newy = (this.Height - this.statusStrip1.Height) / (Y - y);
     float newy = this.Height / Y;
     setControls(newx, newy, this);
     this.Text = this.Width.ToString() +" "+ this.Height.ToString();

 }

 在Form_Load里面添加:

 this.Resize += new EventHandler(Form1_Resize);

 X = this.Width;
 Y = this.Height;
 y = this.statusStrip1.Height;
 setTag (this);

当然定义了两个全局变量,private float X; private float Y;

细心的你一定会发现还有个y ;这是因为有statusStrip1之类的控件,这是就一定要注意,窗体的实际宽度和高度一定要减去statusStrip1之类.

如果是容器,最好将Anchor和Dock属性也修改过来.

效果还不错.

在上面程序中，如果不用到控件的tag属性，可以正常运行。否则会带来问题，所以，在此基础上改进了一下

private void setOriginControlsSize(Control cons)
        {
            foreach (Control con in cons.Controls)
            {
                if (con.Name.Length == 0)
                    continue;
                string strCtlSize = con.Width + ":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;
                dicControls.Add(con.Name, strCtlSize);
                Console.WriteLine("{0}:{1}", con.Name, strCtlSize);
                if (con.Controls.Count > 0)
                    setOriginControlsSize(con);
            }
        }
        private void setNewControlsSize(float newx, float newy, Control cons)
        {
            foreach (Control con in cons.Controls)
            {
                object objCtlSize;
                Console.WriteLine("{0}", con.Name);
                if (false == dicControls.TryGetValue(con.Name, out objCtlSize))
                    continue;
                Console.WriteLine("{0}", objCtlSize);
                string[] mytag = objCtlSize.ToString().Split(new char[] { ':' });
                float a = Convert.ToSingle(mytag[0]) * newx;
                con.Width = (int)a;
                a = Convert.ToSingle(mytag[1]) * newy;
                con.Height = (int)(a);
                a = Convert.ToSingle(mytag[2]) * newx;
                con.Left = (int)(a);
                a = Convert.ToSingle(mytag[3]) * newy;
                con.Top = (int)(a);
                Single currentSize = Convert.ToSingle(mytag[4]) * newy;
                con.Font = new System.Drawing.Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);
                if (con.Controls.Count > 0)
                {
                    setNewControlsSize(newx, newy, con);
                }
            }

        }

需要定义变量 private Dictionary<string, object> dicControls;
