Is it possible to get copyrect without a visual instance of tsynedit?

[Michael Collier]

I'd like to copy the visual view of a TSynEdit onto a TImage canvas.

I have used copyrect to copy the canvas OK, but I'd like to try this without an instance of the TSynEdit being visible.

Is there any way I can do this already? Maybe low level calls or components that I don't know about?

You can use PaintTo:

Code: Pascal  [Select][+][-]

1.       lEdit := TSynEdit.Create(Panel2);
2.       try
3.         lEdit.Parent := Panel2;
4.         lEdit.Lines.LoadFromFile('C:\freepascal\fpc\trunk\packages\rtl-generics\src\generics.collections.pas');
5.         lEdit.PaintTo(Image1.Canvas.Handle, 0, 0);
6.       finally
7.         lEdit.Free;
8.       end;
9.  

But you have to set the parent of the TSynEdit to an invisible Control.

Thanks for the heads up on PaintTo, it works OK for me when the parent panel is visible, but if I hide either the parent panel (panel2) or the synedit (LEdit) the result is a black canvas in the image. Is there any other value I need to set please?
