end;


end.

so. wie beschrieben werden die einträge der der liste mit DrawEntry in die PaintBox1 gemalt und in einem Eintrag werden 2 Images mit der grösse 120x90 gemalt.
und wenn ich über genau eines dieser 120x90 images mit der maus gehe, soll das glaiche Image (über dem sich der cursor befindet) in die PreviewBox gemalt werden.
