C#中Panel控件应用实例
Panel控件1．功能Panel控件用于为其他控件提供可识别的分组。开发Windows应用程序时，通常使用Panel控件按功能细分窗体。在窗体设计时，所有控件都可以自由移动，而当移动Panel控件时，它包含的所有控件也将随着移动。图1为Panel控件。图1 Panel控件2．属性Panel控件常用属性及说明如表1所示。表1 Panel控件常用属性及说明下面详细介绍BackColor属性，此属性用来获取或设置控件的背景色。语法：public virtual Color BackColor { get; set; }属性值：表示控件背景色的Color。默认为DefaultBackColor属性的值。示例BackColor属性的使用本示例中，当程序运行时，单击【颜色】按钮，面板显示背景色。示例运行结果如图2所示。图2 BackColor属性的使用程序主要代码如下：private void button1_Click(object sender, EventArgs e){this.panel1.BackColor = Color.Gray;}完整程序代码如下：本教程来自http://www.isstudy.com/★★★★★主程序文件完整程序代码网站源代码★★★★★using System;using System.Collections.Generic;using System.Windows.Forms;namespace _8_20{static class Program{/// /// 应用程序的主入口点。/// [STAThread]static void Main(){Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);Application.Run(new frmPanel());}}}★★★★★frmPanel窗体设计文件完整程序代码★★★★★using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace _8_20{public partial class frmPanel : Form{public frmPanel(){InitializeComponent();}private void button1_Click(object sender, EventArgs e){this.panel1.BackColor = Color.Gray;}private void button2_Click(object sender, EventArgs e){}private void button3_Click(object sender, EventArgs e){}private void frmPanel_Load(object sender, EventArgs e){}}}★★★★★frmPanel窗体代码文件完整程序代码网站源代码★★★★★namespace _8_20{partial class frmPanel{/// /// 必需的设计器变量。/// private System.ComponentModel.IContainer components = null;/// /// 清理所有正在使用的资源。/// /// 如果应释放托管资源，为 true；否则为 false。protected override void Dispose(bool disposing){if (disposing && (components != null)){components.Dispose();}base.Dispose(disposing);}#region Windows 窗体设计器生成的代码/// /// 设计器支持所需的方法 - 不要/// 使用代码编辑器修改此方法的内容。/// private void InitializeComponent(){this.panel1 = new System.Windows.Forms.Panel();this.label1 = new System.Windows.Forms.Label();this.checkBox1 = new System.Windows.Forms.CheckBox();this.button4 = new System.Windows.Forms.Button();this.button1 = new System.Windows.Forms.Button();this.button2 = new System.Windows.Forms.Button();this.button3 = new System.Windows.Forms.Button();this.panel1.SuspendLayout();this.SuspendLayout();//// panel1//this.panel1.Controls.Add(this.label1);this.panel1.Controls.Add(this.checkBox1);this.panel1.Controls.Add(this.button4);this.panel1.Location = new System.Drawing.Point(12, 12);this.panel1.Name = "panel1";this.panel1.Size = new System.Drawing.Size(200, 100);this.panel1.TabIndex = 0;//// label1//this.label1.AutoSize = true;
