C#實現表單控制項隨表單大小改變(包括字型大小) 修正版

private float X;

private float Y;

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]) * Math.Min(newx,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)
        {
            float  newx = (this.Width )/ X;
            float newy = this.Height / Y;
            setControls(newx, newy, this);
            this.Text = this.Width.ToString() +" "+ this.Height.ToString();

        }

 

在Form_Load裡面添加:  

1. this.Resize += new EventHandler(Form1_Resize);    
2.   
3. //X = this.Width;    

• //Y = this.Height;    

   

• setTag (this);  
• Form1_Resize(new object(),new EventArgs());//x,y可在執行個體化時賦值,最後這句是新加的，在MDI時有用
