AW: TComboboxEx - Icons sind schwarz

  Alt 28. Jul 2012, 06:02
Mit dem Unterschied/Vorbehalt, daß es bei mir um Icons ging:

Delphi-Quellcode:
procedure AddIconToImageList(
        const AFileName : string
      ; var AAddToImageList : TImageList
      );
var
  licnIcon : TIcon;
  lsfiFileInfo: SHFILEINFO;
  limgInter : TImage;
  lsExePath : string;
begin
  // Create a temporary TIcon
  licnIcon := TIcon.Create;
  limgInter := TImage.Create(nil);
  try
    //Get The Icon That Represents The File
    FillChar(lsfiFileInfo, SizeOf(lsfiFileInfo), 0);
    SHGetFileInfo(PChar(AFileName + #0), 0, lsfiFileInfo, SizeOf(lsfiFileInfo), SHGFI_ICON {or SHGFI_LARGEICON});
    licnIcon.Transparent := True;
    licnIcon.Handle := lsfiFileInfo.hIcon;

    // add the icon to the imagelist:
    if Assigned(AAddToImageList) then
    begin
      limgInter.Width := licnIcon.Width;
      limgInter.Height := licnIcon.Height;
      limgInter.Picture.Bitmap.Width := licnIcon.Width;
      limgInter.Picture.Bitmap.Height := licnIcon.Height;
      limgInter.Canvas.FillRect(Rect(0, 0, limgInter.Picture.Bitmap.Width, limgInter.Picture.Bitmap.Height));
      limgInter.Transparent := True;
      limgInter.Picture.Bitmap.TransparentColor := clWhite;

      if DrawIcon(limgInter.Canvas.Handle, 0, 0, licnIcon.Handle) then
      begin
        //
      end
      else
      begin
        licnIcon.ReleaseHandle;
        licnIcon.Handle := GetIconHandleOfExtension(ExtractFileExt(AFileName), lsExePath);
        DrawIcon(limgInter.Canvas.Handle, 0, 0, licnIcon.Handle);
      end;

      AAddToImageList.AddMasked(limgInter.Picture.Bitmap, limgInter.Picture.Bitmap.TransparentColor);
    end;

    DestroyIcon(lsfiFileInfo.hIcon);
  finally
    FreeAndNil(licnIcon);
    FreeAndNil(limgInter);
  end;
end;
