摘要： Delphi2009或者其他的语言说道遍历不是for..in就是直接foreach，Delphi7如何遍历呢？一、遍历枚举 1 //需要引用TpyInfo单元 2 Type 3 TImageType = (jpg,gif,png,bmp,tif,psd); 4 5 var 6 image:TImageType; 7 i:Integer; 8 begin 9 i := 0;10 for image:= Low(TImageType) to High(TImageType) do11 begin12 TpyInfo.GetEnumN... 阅读全文

摘要： 使用的函数DrawPath在绘制直线的时候我们绘制了坐标，我用了多个DrawLine函数堆砌而成，在后来的绘制直线（补充）中和绘制曲线当中都是重复使用DrawLine和DrawBezier函数去实现的。现在使用DrawPath函数可以一次绘制不同组合的图形。DrawPath(Pen,GraphicsPath)GraphicsPath是System.Drawing.Drawing2D命名空间中的一个类，这个类里面有对应GDI+DrawArc,DrawPie,DrawRectangle等等。绘制三角形，四边形，圆，椭圆，直线，曲线，弧度组合。private void Form1_Paint(obj 阅读全文
