BGRAVirtualScreen

[emil]

can't understand: how to assign to a BGRAVirtualScreen a bitmap?

[circular]

It does not work like that.

You can define the OnRedraw event to redraw the bitmap when needed.

[emil]

can you give me please an example, im begginer...

[emil]

Code: [Select]

Procedure TForm1.BGRAVirtualScreen1Redraw(Sender: TObject; Bitmap: TBGRABitmap);
Begin
  bmp.draw(canvas,0,0);
end;

like that?... it doesnt work -.-

the initial idea was to panit a TBGRABitamp on a panel

[circular]

For example:

Code: [Select]

Procedure TForm1.BGRAVirtualScreen1Redraw(Sender: TObject; Bitmap: TBGRABitmap);
Begin
  Bitmap.Fill(CSSBlue);
end;
would fill the virtual screen with blue.

If you want to draw some image on a panel , then you could use a TBCPanel and in the OnAfterRenderBCPanel event, draw some image on it.

In the form creation, load some image:

Code: [Select]

myImage := TBGRABitmap.Create('some filename');
and in the OnAfterRenderBCPanel event:

Code: [Select]

ABGRA.PutImage(0,0,myImage,dmDrawWithTransparency);

actually bgravirtualscreen is a panel, so you can use it as you use a panel. you dont need another panel

Yep that's true
