progressanzeige realisieren

[Klaus01]

Guten Abend,

ein Beispiel wie man es lösen könnte:

Grüße
Klaus

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ExtCtrls, StdCtrls, ComCtrls;

type
  TForm1 = class(TForm)
    ProgressBar1: TProgressBar;    // die alles anzeigt
    ProgressBar2: TProgressBar;   // die einzelne Schritte anzeigt
    Button1: TButton;
    Timer1: TTimer;
    Label1: TLabel;
    procedure Button1Click(Sender: TObject);
    procedure Timer1Timer(Sender: TObject);
  private
    FileSize : Array[0..3] of Integer;
    SizeAll : Integer;
    CurrentFile : Byte;
    Step : Integer;
     Timer : TTimer;
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
  i: Byte;
begin
  FileSize[0]:=200000;
  FileSize[1]:=10000;
  FileSize[2]:=500000;
  FileSize[3]:=30000;

  SizeAll:=0;
  for i:=0 to length(FileSize) do
    SizeAll := SizeAll + FileSize[i];
  CurrentFile:=0;
  Timer1.Interval:=50;
  Timer1.Enabled:=true;
  ProgressBar1.Max:=SizeAll;


end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  step:=5000;
  Label1.Caption:='File '+IntToStr(CurrentFile);
  ProgressBar2.Max:=FileSize[CurrentFile];
  ProgressBar2.Position:=ProgressBar2.Position + step;
  ProgressBar1.Position:=ProgressBar1.Position + step;
  If ProgressBar2.Position >= FileSize[CurrentFile] then
    begin
      inc(CurrentFile);
      ProgressBar2.Position:=0;
      if CurrentFile > Length(FileSize) then
        Timer1.Enabled:=false;
    end;

end;

end.
