如何使用StatusBar控件

我们来看下 定义

public class StatusBar : System.Windows.Forms.Control
    System.Windows.Forms 的成员

摘要:
 表示 Windows 状态栏控件。  

从工具栏中拽一个StatusBar 控件

 

在它的属性中 Panels 中 添加3项

并且更改 各自的Text的值

再来看下代码

 

        private void menuItem2_Click(object sender, System.EventArgs e)
        {//打开文本文件
            this.openFileDialog1.ShowDialog();
            string StrFileName=this.openFileDialog1.FileName;
            if(StrFileName.Trim()=="")
                return;            
            this.richTextBox1.LoadFile(StrFileName,RichTextBoxStreamType.PlainText);            
            this.statusBarPanel1.Text="文件名："+StrFileName;
        }

        private void richTextBox1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
        {//检测鼠标的位置
            int xPos=Cursor.Position.X;
            int yPos=Cursor.Position.Y;            
            this.statusBarPanel2.Text="鼠标位置:X="+xPos.ToString()+"  Y="+yPos.ToString();            
        }

private void richTextBox1_KeyUp(object sender, System.Windows.Forms.KeyEventArgs e)
        {//检测键盘按键状态
            string StrInfo="当前按键为：";
