问题描述
具体代码如下，已经实现图形平移，但是图形被覆盖时，重绘事件做不出来，有知道的吗，敬请指教usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Text;usingSystem.Windows.Forms;usingZedGraph;usingSystem.Drawing.Imaging;usingSystem.Runtime.InteropServices;namespaceGDIPlot{publicpartialclassForm1:Form{GraphPanepicBackground;GraphicstestLine;PenlinePen=newPen(Color.White);intcount=0;intpicWidth;intpicHeight;System.Randomrd=newRandom();intpicOriginX;intpicOriginY;[DllImport("gdi32.dll")]privatestaticexternboolBitBlt(IntPtrhdcDest,intnXDest,intnYDest,intnWidth,intnHeight,IntPtrhdcSrc,intnXSrc,intnYSrc,Int32dwrop);publicForm1(){InitializeComponent();}privatevoidForm1_Load(objectsender,EventArgse){picBackground=zedGraphControl1.GraphPane;picBackground.XAxis.Type=AxisType.DateAsOrdinal;testLine=zedGraphControl1.CreateGraphics();PenlinePen;this.DoubleBuffered=true;}privatevoidForm1_Resize(objectsender,EventArgse){picBackground=zedGraphControl1.GraphPane;textBox1.Text=picBackground.Chart.Rect.X.ToString();textBox2.Text=picBackground.Chart.Rect.Y.ToString();textBox3.Text=picBackground.Chart.Rect.Width.ToString();textBox4.Text=picBackground.Chart.Rect.Height.ToString();}privatevoidzedGraphControl1_MouseDoubleClick(objectsender,MouseEventArgse){textBox5.Text=e.X.ToString();textBox6.Text=e.Y.ToString();}privatevoidbutton1_Click(objectsender,EventArgse){timer1.Enabled=true;timer1.Start();textBox1.Text=picBackground.Chart.Rect.X.ToString();textBox2.Text=picBackground.Chart.Rect.Y.ToString();textBox3.Text=picBackground.Chart.Rect.Width.ToString();textBox4.Text=picBackground.Chart.Rect.Height.ToString();picHeight=(int)(picBackground.Chart.Rect.Height)-4;picWidth=(int)(picBackground.Chart.Rect.Width)-4;picOriginX=(int)picBackground.Chart.Rect.X+4;picOriginY=(int)picBackground.Chart.Rect.Y+3;}privatevoidtimer1_Tick(objectsender,EventArgse){IntPtrihandle=testLine.GetHdc();BitBlt(ihandle,picOriginX+1,picOriginY,picWidth-1,picHeight,ihandle,picOriginX,picOriginY,13369376);testLine.ReleaseHdc(ihandle);for(inti=0;i<picHeight;i++){intrand1=(int)(rd.NextDouble()*255);linePen.Color=Color.FromArgb(rand1,0,255);linePen.Width=1.0F;testLine.DrawLine(linePen,picOriginX,i+picOriginY,picOriginX,i+1+picOriginY);}textBox7.Text=count.ToString();count++;}privatevoidbutton2_Click(objectsender,EventArgse){this.timer1.Stop();}privatevoidzedGraphControl1_Paint(objectsender,PaintEventArgse){//重绘}}}
解决方案
解决方案二：
this.zedGraphControl.AxisChange();this.zedGraphControl.Refresh();
解决方案三：
厄，这个不行啊，这个只是刷新zedgraph控件的坐标啊。我想重绘teseline画的图啊
解决方案四：
谁能告诉我啊，我都愁死了。。。
解决方案五：
在线等啊，有人能解决吗
