示例
以下代码示例在 LocationChanged 调整窗体大小时对 StatusStrip 引发 事件。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
public class Form1 : Form
{
private StatusStrip statusStrip1;
public Form1()
{
InitializeComponent();
}
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
private void InitializeComponent()
{
this.statusStrip1 = new System.Windows.Forms.StatusStrip();
this.SuspendLayout();
//
// statusStrip1
//
this.statusStrip1.Location = new System.Drawing.Point(0, 251);
this.statusStrip1.Name = "statusStrip1";
this.statusStrip1.Size = new System.Drawing.Size(292, 22);
this.statusStrip1.TabIndex = 0;
this.statusStrip1.Text = "statusStrip1";
this.statusStrip1.LocationChanged += new System.EventHandler(this.statusStrip1_LocationChanged);
//
// Form1
//
this.ClientSize = new System.Drawing.Size(292, 273);
this.Controls.Add(this.statusStrip1);
this.Name = "Form1";
this.ResumeLayout(false);
this.PerformLayout();
}
private void statusStrip1_LocationChanged(object sender, EventArgs e)
{
MessageBox.Show("The form has been resized.");
}
}

注解
如果通过编程修改或通过交互更改属性, Location 则会引发此事件。
