| 红尘随笔 作者 2020/9/13 0:32:11 | Delphi中使用richedit控件显示图片 非常简单为其创建一个! var Canvas:TCanvas; Bmp:TBitmap; begin try Canvas:=TCanvas.Create; Canvas.Handle:=GetWindowDC(RichEdit1.Handle); Bmp:=TBitmap.Create; Bmp.LoadFromFile(.....); Canvas.Draw(x,y,bmp); finally ReleaseDC(RichEdit1.Handle,Canvas.Handle)//不可少! Canvas.Free; end; 此方法适合所有从TWinControl继承的控件!TButton,TEdit,TPanel等等! |
