Can TsListBox use PNG images with support for alpha transparency?

I am wondering if TsListBox has this feature and if so how to use it.

Thanks,

Hello Steven

Of course, PNG may be shown on items manually in the OnDrawItem event.

For a drawing of 32-bit bitmaps you can use the CopyByMask procedure. This procedure is implemented in the sGraphUtils module.

Example :

Code:

CopyByMask(DstRect, SrcRect, DstBmp, SrcBitmap, EmptyCI, False);

Also, the TPNGGraphic object have own Draw(ACanvas: TCanvas; const Rect: TRect) procedure.
