Analoguhr

[MrFish]

Ich habe ein Programm für eine Analoguhr geschrieben.
Es ist nur eine Übung gewesen, da ich noch Anfänger bin und mir Delpi selber beibringe.
Ich würde mich freuen wenn ihr mal drüberschaut und sagt was ihr davon haltet.

Delphi-Quellcode:

 unit Uhr;

interface

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

type
  TAnaloguhr = class(TForm)
    Edit1: TEdit;
    Uhr: TTimer;
    procedure UhrTimer(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Analoguhr: TAnaloguhr;
  SecWinkel : integer;
  MinWinkel : Integer;
  StdWinkel : Integer;
  SecWinkelAlt : integer;
  MinWinkelAlt : integer;
  StdWinkelAlt : integer;
  Zeit : String;
  XPos : integer;
  YPos : Integer;
  Std : Integer;
  Min : Integer;
  Sec : Integer;


implementation

{$R *.dfm}

procedure TAnaloguhr.UhrTimer(Sender: TObject);


begin
{---------------Systemzeit auslesen und zuweisen -------------------}

Zeit := TimeToStr(Time);
Edit1.Text := Zeit;
Std := StrToInt(Copy(Zeit,1,2));
Min := StrToInt(Copy(Zeit,4,2));
Sec := StrToInt(Copy(Zeit,7,2));

{-------------Zeigerwinkel berechnen--------------------------------}

SecWinkel := (( 6 * Sec)+90);
MinWinkel := (( 6 * Min)+90);
StdWinkel := ((30 * Std)+90);

{------------Zeiger Löschen-----------------------------------------}
{-------------Sekunde-----------------------------------------------}

XPos := Trunc (cos(SecWinkelAlt * Pi /180) *(-100));
YPos := Trunc (sin(SecWinkelAlt * Pi /180) *(-100));

Canvas.MoveTo(150,150);
Canvas.Pen.Color := clBtnFace;
Canvas.Pen.Width := 1;
Canvas.LineTo((XPos + 150),(YPos + 150));

{--------------Minuten---------------------------------------------}

XPos := Trunc (cos(MinWinkelAlt * Pi /180) *(-100));
YPos := Trunc (sin(MinWinkelAlt * Pi /180) *(-100));

Canvas.MoveTo(150,150);
Canvas.Pen.Color := clBtnFace;
Canvas.Pen.Width := 3;
Canvas.LineTo((XPos + 150),(YPos + 150));

{--------------Stunde----------------------------------------------}

XPos := Trunc (cos(StdWinkelAlt * Pi /180) *(-80));
YPos := Trunc (sin(StdWinkelAlt * Pi /180) *(-80));

Canvas.MoveTo(150,150);
Canvas.Pen.Color := clBtnFace;
Canvas.Pen.Width := 3;
Canvas.LineTo((XPos + 150),(YPos + 150));


{-------------Zeiger Zeichnen---------------------------------------}
{-------------Sekunde-----------------------------------------------}

XPos := Trunc (cos(SecWinkel * Pi /180) *(-100));
YPos := Trunc (sin(SecWinkel * Pi /180) *(-100));

Canvas.MoveTo(150,150);
Canvas.Pen.Color := 0;
Canvas.Pen.Width := 1;
Canvas.LineTo((XPos + 150),(YPos + 150));

{--------------Minuten---------------------------------------------}

XPos := Trunc (cos(MinWinkel * Pi /180) *(-100));
YPos := Trunc (sin(MinWinkel * Pi /180) *(-100));

Canvas.MoveTo(150,150);
Canvas.Pen.Color := 0;
Canvas.Pen.Width := 3;
Canvas.LineTo((XPos + 150),(YPos + 150));

{--------------Stunde----------------------------------------------}

XPos := Trunc (cos(StdWinkel * Pi /180) *(-80));
YPos := Trunc (sin(StdWinkel * Pi /180) *(-80));

Canvas.MoveTo(150,150);
Canvas.Pen.Color := 0;
Canvas.Pen.Width := 3;
Canvas.LineTo((XPos + 150),(YPos + 150));

{------------Alte Winkel Zwischenspeichern-------------------------}

SecWinkelAlt := SecWinkel;
MinWinkelAlt := MinWinkel;
StdWinkelAlt := StdWinkel;


end;

end.
