WonForm 字幕滚动解决思路

WonForm 字幕滚动
这几天做一个WinForm的东西 出现了好多问题、
 现在做个字幕向上滚动的窗体、弄来弄始终达不到要求、在窗体上放了两个Panel、顶端那个显示标题、底端那个显示时间等等、中间的信息要向上循环滚动、我放在一个GroupBox里的、但是滚上去总会盖住顶端的那个Panel,我又在中间放了一个Panel，再把GroupBox放在Panel里、让他在Panel里滚动、但是滚上去了就没有了、怎么能循环滚动啊、上边滚完了、下边又出来继续滚，还有就是说 GroupBox.Width=窗体.Width或者Panel.Width=窗体.Width能不能这样设啊、怎么没反应啊 废话有点多、怕说不清楚 能不能说下具体思路啊、谢谢、、、、、

[解决办法]

C# code

Action 委托方法 = () => { 移动字幕.Left = 移动字幕.Left - 1; if (移动字幕.Right < 0) 移动字幕.Left = this.Width; };委托方法();

添加以下类至代码页：
C# code
using Microsoft.VisualBasic;using System;using System.Collections;using System.Collections.Generic;using System.Data;using System.Diagnostics;public class ScrollStringLib{    private Control _Ct;    private Color _TextColor;    private Bitmap _TextLayer;    private System.Timers.Timer withEventsField__Timer = new System.Timers.Timer();    private System.Timers.Timer _Timer {        get { return withEventsField__Timer; }        set {            if (withEventsField__Timer != null) {                withEventsField__Timer.Elapsed -= _Timer_Elapsed;            }            withEventsField__Timer = value;            if (withEventsField__Timer != null) {                withEventsField__Timer.Elapsed += _Timer_Elapsed;            }        }    }    private int _ScrollnIndex = 0;    private Bitmap _tempBmp;    public void ScrollStop()    {        _Timer.Stop();    }    public void ScrollStart(Control Ct, string Text, Color TextColor, int Speed)    {        _Ct = Ct;        if (_TextLayer != null)            _TextLayer.Dispose();        Size Sz = Ct.CreateGraphics.MeasureString(Text, _Ct.Font, _Ct.Width).ToSize;        Sz = new Size(Sz.Width + 10, Sz.Height + 10);        _TextLayer = new Bitmap(Sz.Width, Sz.Height);        using (Graphics G = Graphics.FromImage(_TextLayer)) {            G.DrawString(Text, _Ct.Font, new SolidBrush(TextColor), new Rectangle(0, 0, Sz.Width, Sz.Height));        }        _Timer.Interval = Speed;        _Timer.Start();    }    private void _Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)    {        try {            if (_tempBmp != null)                _tempBmp.Dispose();            _tempBmp = new Bitmap(_Ct.Width, _Ct.Height);            using (Graphics G = Graphics.FromImage(_tempBmp)) {                _ScrollnIndex -= 1;                if (_TextLayer != null) {                    if (_ScrollnIndex <= -_TextLayer.Height)                        _ScrollnIndex = 0;                    G.DrawImage(_TextLayer, new Rectangle(0, _ScrollnIndex, _Ct.Width, _Ct.Height), new Rectangle(0, 0, _Ct.Width, _Ct.Height), GraphicsUnit.Pixel);                }            }            _Ct.BackgroundImage = _tempBmp;        } catch {        }    }}
[解决办法]
探讨

可是里边的内容不随着我的窗体变化而变化啊、内容的排放是根据窗体宽度排放的、也设了控件的宽度等于窗体的宽度、现在拉宽窗体、内容没什么反应啊、

[解决办法]
if (滚完了)
{
重新开始;
}
