窗体设置

1. 窗体设置

　　1.1 窗体大小

　　　　在窗体的Load事件中编写 this.MaximumSize = new Size(长,宽);

　　1.2 新增窗体

　　　　新建工程, 默认为Form1. 在程序右键Add Windows Form新建一个窗体程序, 默认为Form2

　　　　在Form1上添加一Button, Button_Click中添加下面代码　　

1 private void button1_Click(object sender, EventArgs e)
2         {
3             Form2 frm = new Form2();
4             frm.Show();
5
6         }

　　　　点击按钮就会产生Form2

　　1.3 窗体透明度

private void button1_Click(object sender, EventArgs e)
        {
            Form2 frm = new Form2();
            frm.Opacity = 0.3;  //透明度=1为不透明, 0为完全透明
            frm.Show();
        }

　　　　可以设置透明度逐渐增大的效果, 透明度对窗体上所有控件有效

　　1.4 控件移动

　　　　实现点击Form1的Button产生Form2, 点击Form1上的label控件, Label控件移动到Form2上, 再次点击则返回Form1　

 1 using System;
 2 using System.Collections.Generic;
 3 using System.ComponentModel;
 4 using System.Data;
 5 using System.Drawing;
 6 using System.Linq;
 7 using System.Text;
 8 using System.Windows.Forms;
 9
10 namespace Windows
11 {
12     public partial class Form1 : Form
13     {
14         public Form1()
15         {
16             InitializeComponent();
17         }
18
19         Form2 form2;  //声明Form2
20
21         private void button1_Click(object sender, EventArgs e)
22         {
23             form2 = new Form2();  //实例化窗体
24             form2.Show();       //显示窗体
25         }
26
27         private void labelMove_Click(object sender, EventArgs e)
28         {
29             if (this.labelMove.Parent == this)      //判断准备移动的控件位于当前Form1中
30             {
31                 form2.Controls.Add(this.labelMove);   //将该控件添加到Form2中了, 在Form1上消失了
32                 this.labelMove.Text = "返回";
33             }
34             else {
35                 this.Controls.Add(this.labelMove);
36                 this.labelMove.Text = "移动";
37             }
38         }
39     }
40 }

　　1.5 根据窗体自动调整控件大小

 1 using System;
 2 using System.Collections.Generic;
 3 using System.ComponentModel;
 4 using System.Data;
 5 using System.Drawing;
 6 using System.Linq;
 7 using System.Text;
 8 using System.Windows.Forms;
 9
10 namespace Windows2
11 {
12     public partial class Form1 : Form
13     {
14         public Form1()
15         {
16             InitializeComponent();
17         }
18
19         private float X;private float Y;
20
21         private void Form1_Load(object sender, EventArgs e)
22         {
23             this.Resize += new EventHandler(Form1_Resize);  //窗体调整大小事件时执行的方法
24             X = this.Width;
25             Y = this.Height;
26             setTag(this);
27         }
28
29         private void Form1_Resize(object sender, EventArgs e)
30         {
31             float newx = (this.Width) / X;
32             float newy = (this.Height) / Y;
33             setControls(newx, newy, this);
34             this.Text = this.Width.ToString() + " " + this.Height.ToString();  //窗体标题栏文本
35
36         }
37
38         private void setTag(Control cons){
39         //获取控件的 width , height , left , top , 字体大小存放在控件的 Tag属性中
40             foreach (Control con in cons.Controls) {  //遍历窗体所有控件
41                 con.Tag = con.Width + ":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;
42                 if (con.Controls.Count > 0)
43                     setTag(con);  //递归调用
44             }
45         }
46
47         private void setControls(float newx, float newy, Control cons){  //根据窗体大小调整控件大小
48             foreach (Control con in cons.Controls) {
49                 string[] mytag = con.Tag.ToString().Split(new char[] { ‘:‘ });  //获取控件的Tag属性值, 并分割后存储字符数组
50                 float a;
51                 a = Convert.ToSingle(mytag[0]) * newx;
52                 con.Width = (int)a;
53                 a = Convert.ToSingle(mytag[1]) * newy;
54                 con.Height = (int)(a);
55                 a = Convert.ToSingle(mytag[2]) * newx;
56                 con.Left = (int)(a);
57                 a = Convert.ToSingle(mytag[3]) * newy;
58                 con.Top = (int)(a);
59                 Single currentSize = Convert.ToSingle(mytag[4]) * newy;
60                 con.Font = new Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);
61                 if (con.Controls.Count > 0)
62                 {
63                     setControls(newx, newy, con);
64                 }
65             }
66         }
67     }
68 }
