Question

用form1.Canvas怎么样显示背景图片？？

Answer 1

为什么不用image控件？
如果想直接在form上显示，用copyrect的方法

Answer 2

canvas.Draw(0,0,image1.Picture.Graphic);
或
bitblt(Canvas.Handle,0,0,image1.Picture.Bitmap.Width,
       image1.Picture.Bitmap.Height,image1.canvas.Handle,0,0,srccopy);

Answer 3

显示一个背景图片也要用image，太浪费了。
Var
bj:tbitamp;
......
form1.brush.bitmap:=bj;

Answer 4

var pic:timage;
begin
pic:=timage.Create(self);
pic.Picture.LoadFromFile('C:\aa.jpg');
TreeView1.canvas.Draw(0,0,pic.Picture.Graphic);
