Many web pages have background patterns that make the page look more eye-catching. However, you can also design this type of form in Delphi. One method that immediately comes to mind is to use the image component and then specify a picture. This is of course feasible, but a BMP image that can fill the entire form will take up a lot of memory space, so it is not worthwhile. The best way is to just download a very small BMP image and paste it over the entire form.
Instead of using the Image component, the Bitmap component is used to download a small bitmap. Add variable definition to the Public section: Bitmap: TBitmap; then generate this object in the OnCreate event of the form, the code is as follows:
PRocedure TForm1.FormCreate(Sender:Tobject);
begin Bitmap:=TBitmap.Create;??
Bitmap.LoadFormFile('1.bmp');//Picture file 1.bmp is only 1KB in size??
end;
The third step is to paste the bitmap pattern onto the entire form in the OnPaint event of the form. Add the following code:??procedure TForm1.FormPaint(Sender:Tobject)var x,y:integer;begin y:=0;while y do begin X:=0; while X do begin cancas.Draw(X,Y,Bitmap);?? X:=X+Bitmap.Width; end; Y:=Y+Bitmap.Heigth; end;end;Forgot to release the Bitmap object in the OnDestory event of the form. Specific code: Bitmap.Free; OK, when the form is displayed, it will have a background like a web page, and it does not take up much memory space.
