How to fill a ScrollBox from ListView items

I have a ListView with a number of fields inside of it.

On the other side, I have a ScrollBox that I want to fill in with data from the ListView.

This is done by creating a dynamic panel that contains a set of Labels to represent the data on the panel.

image

unit Unit3;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.ExtCtrls, Vcl.StdCtrls,
  PngImageList, Vcl.Menus,
  Vcl.ComCtrls, siComp, Registry, System.ImageList, Vcl.ImgList,
  Vcl.Imaging.pngimage, rkGlassButton;

type
  TForm3 = class(TForm)
    ScrollBox1: TScrollBox;
    LV: TListView;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form3: TForm3;
  Pnl : TPanel;
 LabName : TLabel;
 LabId : TLabel;

implementation

{$R *.dfm}

procedure TForm3.Button1Click(Sender: TObject);
var
 posX,posY : SmallInt;

  I: Byte;
  Item: TListItem;

begin

   posX := 0;
   posY := 0;
   for I := 0 to LV.Items.Count -1 do
    begin
      Pnl := TPanel.Create(ScrollBox1);
      Pnl.Parent           := ScrollBox1;
      Pnl.Left             := posX  -1;
      Pnl.Top              := posY  -1;
      Pnl.Width            := ScrollBox1.Width;
      Pnl.Height           := 40;
      Pnl.BorderStyle      := bsNone;
      Pnl.BevelInner       := bvNone;
      Pnl.BevelKind        := bkNone;
      Pnl.BevelOuter       := bvNone;
      Pnl.ParentBackground := false;
      Pnl.Color            := clWhite;
      Pnl.Anchors          := [akTop, akRight,akLeft];
      posY := posY + Pnl.Height;
     //-------------------
        LabName := TLabel.Create(Pnl);
        LabName.Parent := Pnl;
        LabName.Top := 10;
        LabName.Left := 40;;
        LabName.Font.Size := 11;
        LabName.Caption :=LV.Items; // ??? ListView  (RN)
    //--------------------
        LabId := TLabel.Create(Pnl);
        LabId.Parent := Pnl;
        LabId.Top := 10;
        LabId.Left := 100;;
        LabId.Font.Size := 11;
        Item := LV.Items;
        LabId.Caption := LV.Items;; // ???  ListView  (RC)
    end;
end;

end.

The panel is well constructed, but I do not know how to set the label captions using items in the ListView.

Please help me to correct my code.

It seems like you are looking for LV.Items[i].Caption and LV.Items[i].SubItems[j].

  • Caption is the text in the left-most cell.
  • SubItems[0], SubItems[1], ..., SubItems[LV.Columns.Count - 2] yield the texts in the remaining cells.

So, in your case, given row i,

  • LV.Items[i].Caption is the value in the "RN" column.
  • LV.Items[i].SubItems[0] is the value in the "RC" column.
  • LV.Items[i].SubItems[1] is the value in the "RFD" column.
  • LV.Items[i].SubItems[2] is the value in the "RUR" column.
  • LV.Items[i].SubItems[3] is the value in the "RID" column.
  • LV.Items[i].SubItems[4] is the value in the "isV" column.
