Graphics::tbitmap *pbitmap; int offset=2;pcanvas->fillrect(rect);......if(pbitmap){ pcanvas->brushcopy(bounds(rect.oeft+offset,rect.top,pbitmap->width,pbitmap->height),pbitmap,
Graphics::tbitmap *pbitmap; int offset=2;pcanvas->fillrect(rect);......if(pbitmap){ pcanvas->brushcopy(bounds(rect.oeft+offset,rect.top,pbitmap->width,pbitmap->height),pbitmap,
