    TUniListBox scroll programatically

    in General

    Posted

    image.png.7f006e73bd82a2506d94e97a37e8cacf.png  When key press over the list box (multiselect and ordered), the item is selected, but the scroll doesn´t move to that item.

    Ex. Press G words from the keyboard and listbox stays same as before, but, if manually scroll the list until found an item beginning with G, that item seems selected!

    How move the scroll programatically until the selected item?

     

     

    TUniChart Series Mouse Move and hint (tooltips)

    in General

    Posted

    I've 4 Series series in UniChart, with data for 4 years, each one is 1 year. (for anything type: area, bar, pie, scatter, radar, etc.)
    When mouse move over the series, and values triggers  

    SeriesMouseOver(Sender: TUniCustomChart; Series: TUniChartSeries; Index: Integer; Value: Variant; X, Y, PageX,   PageY: Integer);

    But always the series and Index are same, never changes. Only first serie is recognizing. I need the others too.!
     

    I try with tooltips in javascript (from Delphi):

    //graphic1 is TuniChart component 

        graphic1.ClientEvents.UniEvents.Add(
        'chart.beforeInit=function chart.beforeInit(sender, config){'+
        '  config.innerPadding = {left: 4,right: 5};'+
        '  if (config.series.length) { '+
        '    for (i = 0; i < config.series.length; i++) {'+
        '      config.series[i].tooltip = {'+
        '        trackMouse: true,'+
        '        width: 150,'+
        '        renderer: function(tip, item) {'+
        '          tip.setTitle(item.get(''LL''));'+
        '          tip.update(''Valor: '' + item.get(String.fromCharCode(65+i)));'+
        '        }'+
        '      }'+
        '    }'+
        '  }'+
        '}');                                          

    But when mouse moves over the graphic... only values from 1 serie shows, and same value when moving over anothers series.

    How can catch de current serie and current value?


     


     

    Create unilineseries dynamically

    I've created a new application and your code works fine.

    However at my app that opens a frame to a tab at mainform does not work.

    Works only if I created unilineseries at designtime, and have Unichart1.SeriesList.Clear; at the start of your code.

    And you have to create the number of series that you want at design time.... Perhaps it is a bug!

    I see only works on FormCreate event.
    Normally want to create series at runtime, by clicking a button, for example.  It doesn't work there.

    I found that the only way to do it is to create the chart also at runtime which is extremely laborious, crazy.

    Is there any method that makes the graph "refresh" the series that are created at runtime, such as a reInit, or Init, or destroy and init ... what would be the solution?

    How to modify the UniDBNavigator hint content?

    More data

    I need change the hint, too. 
    Which is the resourcestring file for change the resourcestring value?

    I take example from http://www.delphibasics.info/home/delphibasicssnippets/changeresourcestringsatruntime

    And put that procedure HookResourceString(rs: PResStringRec; newStr: PChar); 

    I was tested on ServerModuleCreate, MainModuleCreate and MainFormCreate and nothing ....

    using Vcl.Consts,  Vcl.VDBConsts 

    procedure TUniServerModule.UniGUIServerModuleCreate(Sender: TObject);
begin
  HookResourceString(@SFirstRecord,          'Primer registro');
  HookResourceString(@SPriorRecord,          'Registro anterior');
  HookResourceString(@SNextRecord,           'Siguiente registro');
  HookResourceString(@SLastRecord,           'Último registro');
  HookResourceString(@SInsertRecord,         'Agregar');
  HookResourceString(@SDeleteRecord,         'Eliminar');
  HookResourceString(@SEditRecord,           'Editar');
  HookResourceString(@SPostEdit,             'Grabar');
  HookResourceString(@SCancelEdit,           'Cancelar edición');
  HookResourceString(@SConfirmCaption,       'Confirmar');
  HookResourceString(@SRefreshRecord,        'Refrescar');
  HookResourceString(@SDeleteRecordQuestion, 'Eliminar registro?');
end;

    it still showing in English

    Image area or region

    in General

    Posted

    How is possible define areas or regions in a TUniImage?

    Ex.. Show some flags in an unique picture, and when click in each flag do something ... as redirect to another form, or another website ... 

     

    Or better, show a image map (as attached), and click in a country for do something

    In HTML is there map and area tags ... but ... never must change size of controls to make it works

    Digital Sign in PDF

    in General

    Posted

    I'm using TUniPDFFrame to show PDF files, but this component doesn't show the advertisement about digital sign.

    The client need to see that notice. (adj. images)

     

    Also, I need to know if an uploaded pdf is digitally signed before save on BD.

    Could there be any property that indicates whether it is signed or not?.
    Ex.
    
  bool hasSig = false;
            for (int i = 1; i <= QP.FormFieldCount(); i++)
                if (QP.GetFormFieldType(i) == 6)     // FormFieldType = Signature
                    hasSig = true;

    taken from  http://www.quickpdf.org/forum/how-do-i-detect-that-a-pdf-has-a-digital-signature_topic2529_post10489.html?KW=FormFieldType#10489

    Problema de MessageDlg y open.window

    in Spanish

    Posted

     Ejemplo al presionar el botón ok

    procedure btnOKClick(Sender: TObject);
  procedure Imprimir;
  begin
    UniMainModule.CrearWebFilePath;
    UniSession.AddJS('window.open('+QuotedStr(UniMainModule.WebFilePath)+',"_blank", "status=no,location=no,resizable=no,dependent=yes,toolbar=no,menubar=no", "false");' );
  end;
begin
  UniScreenMask1.AttachedControl := btnOk;
  UniScreenMask1.TargetControl   := Self;
  Self.MessageDlg('Desea imprimir el contenido?', mtConfirmation, mbYesNo,
        procedure (Sender: TComponent; Res: Integer)
        var cerrarModal: boolean;
        begin
          cerrarModal := Res = mrNo;
          if not cerrarModal then
            Imprimir
          else
            CloseModal;
        end);
end;

    En ese ejemplo no sale nunca el mensaje, y mucho menos se abre la nueva ventana que contendría el archivo pdf a imprimir.

    La prueba fue hecha sobre Chrome.
    Porqué puede ser que no dispare el messagedlg?. Tampoco cierra el form porque nunca se ejecuta el callback
