  1. Hi All, i'm testing tfgCollectionView with this rest resource : http://jsonplaceholder.typicode.com/photos In this test my CollectionView Style has 1 fgImage and 1 fgLabel. I get the RestResouce with a TRESTRequest.ExecuteAsync and it works perfectly. When i've the ExecuteAsync CallBack i parse the JSON output string and i fill my Photos collection (TList). I do this step with a separate Task because i've 5000 items ( more or less). When i link data to the CollectionView i call fgCollectionViewGetItemCount and fgCollectionView1BindItem. If i bind only the fgLabel all works perfectly. My problem is link the tfgImage to the thumbnail. I post my code: procedure TFramePhoto.fgCollectionView1BindItem(Sender: TObject;const AIndex: Integer; const AStyle: string; const AItem: TfgItemWrapper); VAR Item:TPhotoData; begin TRY Item:=RestPhotos.Items[AIndex]; AItem.GetControlByLookupName<TfgLabel>('LblTitle').Text := Item.Ftitle; TfgAssetsManager.Current.AddBitmapFromUrlAsync(Item.FalbumId, Item.FthumbnailUrl, procedure (const AResultCode: Integer; const AResultMessage: string) begin AItem.GetControlByLookupName<TfgImage>('ImgAlbum').ImageName := Item.FalbumId; end); EXCEPT ON E:EXCEPTION DO FGX.Log.TfgLog.Log(TfgLogLevel.Debug,'fgCollectionView1BindItem ' + e.Message); END; end; Actually i'm saving the images in assets but i think it is a bad idea... Can you suggest a best practice for this scenario ? Thanks a lot guys, Best Regards.
  2. Hi All, I'm trying to use a tfgSearchEdit with a tfgCollectionView. I'm searching the better way to set the focus to the CollectionViewitem that match my search value. There is a demo that explain this management ? I've seen that i can fill the SearchEdit.Suggestions with the CollectionViewItems field otherwise i can do a binarysearch in the Tlist<> that is linked to the CollectionView but i've to sort the list. Can you suggest a best practise for that ? Thanks a lot, Luca.
  3. Hi All, i've tryied to manage the event fgListMenuItemOnTap as written below and i've seen that the Sender is not a fgListMenuItem object but fgListMenu. procedure TFormMain.fgListMenu1Items0Tap(Sender: TObject); begin fgLabel3.Text := Sender.ToString(); end; In this way i'm not able to understand witch item i've pressed so i've to manage each onItemTap with a specific event. Is it normal or i'm doing a mistake ? Thanks a lot, Luca.
  4. Hi all, just for sample i'm trying to put a square in the form center, and a circle in the square center. I've placed a layout with FlexGrow=1 so it will take all the form space and AlignmentChildren.JustifyContent=Center. Into the layout i've placed the square with PositionMode=relative. Now if i try to put the circle i can't use relative position but only absolute and i've to place the circle in the center without any support. How i can solve ? Thanks a lot, Best Regards.
  5. Hi Yaroslav, I've solved. I've made a wrong usage of TfgAnimationHelper... Thank you.
  6. Hi Yaroslav, i attach my test project. As you can see in the FrmLogin i call FrmWait with this code : FrmWait := TFrmWait.Create(nil); TfgAnimationHelper.ShowForm(FrmWait); in FrmWait i've this method : procedure TFrmWait.fgFormCreate(Sender: TObject); begin TfgAnimationHelper.FadeOut(LblInfo, [TfgAnimationOption.StartFromCurrent], 0); LblInfo.Text:='Ciao Luca'; TfgAnimationHelper.FadeIn(LblInfo, [TfgAnimationOption.StartFromCurrent], 500); Sleep(2000); TfgAnimationHelper.FadeOut(LblInfo, [TfgAnimationOption.StartFromCurrent], 500); sleep(500); LblInfo.Text:='Abbiamo quasi finito...'; TfgAnimationHelper.FadeIn(LblInfo, [TfgAnimationOption.StartFromCurrent], 500); Sleep(2000); TfgAnimationHelper.FadeOut(LblInfo, [TfgAnimationOption.StartFromCurrent], 500); end; and this event freeze the current form. I think i can fix with TfgCallBack from TfgAnimationHelper.ShowForm but i'm not sure and i don't know how to use it. Thanks a lot. FMX.7z
