a771948524 人气:0想了解WinForm实现状态栏跑马灯效果的方法示例的相关内容吗,a771948524在本文为您仔细讲解WinForm状态栏跑马灯效果的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:WinForm,状态栏,跑马灯,下面大家一起来学习吧。
本文实例讲述了WinForm实现状态栏跑马灯效果的方法。分享给大家供大家参考,具体如下:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private Label label = new Label(); public string text = "csdn baihe_591"; private void Form1_Load(object sender, EventArgs e) { this.label.Location = new Point(149, 13); this.label.Size = new Size(134, 16); this.Controls.Add(label); this.label.Text = ""; this.timer1.Enabled = true; this.timer1.Interval = 500; p = new PointF(this.label.Size.Width, 0); } PointF p; Font f = new Font("宋体", 10); Color c = Color.White; string temp; private void timer1_Tick(object sender, EventArgs e) { Graphics g = this.label.CreateGraphics(); SizeF s = new SizeF(); s = g.MeasureString(text, f);//测量文字长度 Brush brush = Brushes.Black; g.Clear(c);//清除背景 if (temp != text)//文字改变时,重新显示 { p = new PointF(this.label.Size.Width, 0); temp = text; } else p = new PointF(p.X - 10, 0);//每次偏移10 if (p.X <= -s.Width) p = new PointF(this.label.Size.Width, 0); g.DrawString(text, f, brush, p); } } }
希望本文所述对大家C#程序设计有所帮助。
