我心依旧 通过本文主要向大家介绍了java实现视频播放器,qt实现视频播放器,winform滚动字幕,winform滚动,winform滚动条等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
本文实例讲述了WinForm实现仿视频播放器左下角滚动新闻效果的方法。分享给大家供大家参考。具体实现方法如下：
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;
using System.Drawing.Imaging;
using System.IO;
using System.Xml.Linq;
namespace App
{
public partial class Form7 : Form
{
private int Index { get; set; }
private DataTable dataTable { get; set; }
private System.Timers.Timer timer { get; set; }
public Form7()
{
InitializeComponent();
dataTable = new DataTable();
dataTable.Columns.AddRange(new DataColumn[] {
new DataColumn("Id",typeof(System.Int32)),
new DataColumn("DisplayName",typeof(System.String)),
new DataColumn("URL",typeof(System.String))
});
DataRow row = dataTable.NewRow();
row["Id"] = 1;
row["DisplayName"] = "百度百科欢迎你!";
row["URL"] = "http://www.baidu.com";
dataTable.Rows.Add(row);
row = dataTable.NewRow();
row["Id"] = 2;
row["DisplayName"] = "刘XX明星已经现身搜狐网站，赶快去围观!";
row["URL"] = "http://www.sohu.com";
dataTable.Rows.Add(row);
row = dataTable.NewRow();
row["Id"] = 3;
row["DisplayName"] = "新浪新闻出现重大新闻，点我快速查看!";
row["URL"] = "http://www.sina.com.cn";
dataTable.Rows.Add(row);
row = dataTable.NewRow();
row["Id"] = 4;
row["DisplayName"] = "网易客户端出现新版本啦，赶快去体验把!";
row["URL"] = "http://www.126.com";
dataTable.Rows.Add(row);
label1.Text = lblContent.Top.ToString();
timer = new System.Timers.Timer(2000);
timer.Elapsed += delegate
{
CharsMouse();
};
timer.Start();
button1.Click += delegate
{
CharsMouse();
};
button2.Click += delegate
{
timer.Dispose();
};
lblContent.LinkClicked += delegate
{
label2.Text = dataTable.Rows[Index]["URL"].ToString();
};
}
void CharsMouse()
{
this.lblContent.Invoke(new MethodInvoker(delegate
{
if (Index >= dataTable.Rows.Count)
Index = 0;
while (lblContent.Top > -lblContent.Height)
{
lblContent.Top = lblContent.Top - 2;
label1.Text = "1.Top=" + lblContent.Top.ToString();
System.Threading.Thread.Sleep(100);
Application.DoEvents();
}
lblContent.Text = dataTable.Rows[Index]["DisplayName"].ToString();
lblContent.Top = 2;
timer.Enabled = false;
Application.DoEvents();
System.Threading.Thread.Sleep(2000);
timer.Enabled = true;
Index++;
}));
}
}
}
