• winform中,如何控制控件位置随窗体的大小改变而改变


    有如下3种方法:

    方法1

    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Text;
    using System.Windows.Forms;

    namespace MarkPrinter
    {
        public partial class ResizeTest : Form
        {
            public float X;
            public float Y;
            public float y;

            public ResizeTest()
            {
                InitializeComponent();
            }

            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;

                    //改变字体大小
                    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();

            }

            private void ResizeTest_Load(object sender, EventArgs e)
            {
                this.Resize += new EventHandler(Form1_Resize);

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

    方法2

    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Text;
    using System.Windows.Forms;

    namespace MarkPrinter
    {
        public partial class ResizeTest : Form
        {
            public float X;
            public float Y;
            public float y;

            public ResizeTest()
            {
                InitializeComponent();
            }

            private void ResizeTest_Load(object sender, EventArgs e)
            {
                AutoScale(this);
            }

            /// <summary> 
            /// 控件随窗体自动缩放 
            /// </summary> 
            /// <param name="frm"></param> 
            public static void AutoScale(Form frm)
            {
                frm.Tag = frm.Width.ToString() + "," + frm.Height.ToString();
                frm.SizeChanged += new EventHandler(frm_SizeChanged);
            }

            static void frm_SizeChanged(object sender, EventArgs e)
            {
                string[] tmp = ((Form)sender).Tag.ToString().Split(',');
                float width = (float)((Form)sender).Width / (float)Convert.ToInt16(tmp[0]);
                float heigth = (float)((Form)sender).Height / (float)Convert.ToInt16(tmp[1]);

                ((Form)sender).Tag = ((Form)sender).Width.ToString() + "," + ((Form)sender).Height;

                foreach (Control control in ((Form)sender).Controls)
                {
                    control.Scale(new SizeF(width, heigth));

                }
            }
        }
    }

    用此方法时,如果界面一开始就要求最大化,在最大化之前就要调用AutoScale方法

    方法3

    将控件放进容器中, 然后使用控件的Dock属性来获取或设置控件停靠到父容器的哪一个边缘。
