BAB VI APLIKASI JAM DIGITAL DAN ANALOG
A. DESAIN FORM
Dengan menggunakan komponen MainMenu, StaticText serta Timer dan PaintBox, buatlah desain form seperti dibawah ini:
Gambar 6.1. Desain Form Jam

B. SOURCE CODE
Seperti halnya dialam pascal, dalam program delphi ini kita juga bisa membuat prosedur sendiri. Caranya ketik dahulu Header prosedur
yang akan dibuat Bagian kepala prosedur dan tempatkan dibagian private atau public. Misalkan kita ingin membuat prosedur BingkaiJam,
JamDigital, dan JamAnalog maka anda harus mengetikkannya pada bagian private sehingga terlihat sebagai berikut:
xjam,yjam,xmen,ymen,xdet,ydet : integer; procedure JamAnalogSender : TObject;
procedure JamDigitalSender : TObject; procedure BingkaiJam;
Kemudian anda ketik isi prosedur tersebut dibagian implementation:
procedure TForm1.JamAnalogSender : TObject; Var
AmpJam,AmpMen,AmpDet,Jam,Men,Det,Det100 :
word; Begin
Gambar Jam: SetMapModepaintbox1.Canvas.Handle, MM_LOMETRIC;
SetViewPortOrgExPaintBox1.Canvas.Handle, PaintBox1.Width div 2,
PaintBox1.Height div 2, nil; If PaintBox1.HeightPaintBox1.Width Then
AmpDet := PaintBox1.Height div 2 -10 Else
AmpDet := PaintBox1.Width div 2 -10; Set Panjang Jarum Jam,Menit, dan Detik
AmpDet := AmpDet3 div 2; AmpMen := AmpDet-20;
AmpJam := AmpMen-30; DecodeTimeTime,Jam,Men,Det,Det100; catat
waktu ini With PaintBox1.Canvas DO
Begin Pen.Color := clBtnFace;

MoveTo0,0; LineToxdet,ydet; Gambar Jarum Menit:
Pen.Color := clBlack; MoveTo0,0; LineToxmen,ymen;
Gambar Jarum Jam MoveTo0,0; LineToxjam,yjam;
End; End;
procedure TForm1.JamDigitalSender:TObject; Begin
lblJam.Caption := TIMEtoSTRTime; End;
procedure TForm1.BingkaiJam; Var Amp,Amp1,i :integer;
Begin Gambar Jam:
SetMapModepaintbox1.Canvas.Handle, MM_LOMETRIC; SetViewPortOrgExPaintBox1.Canvas.Handle,
PaintBox1.Width div 2, PaintBox1.Height div 2, nil;
If PaintBox1.HeightPaintBox1.Width Then Amp := PaintBox1.Height div 2 -10
Else Amp := PaintBox1.Width div 2 -10;
Set Panjang Jarum Jam,Menit,Detik: Amp := Amp3 div 2;
Amp1 := Amp - 10; For i:=0 to 60 Do
Begin If
i mod
5 =0
Then PaintBox1.Canvas.Pen.Color := clRed
Else PaintBox1.Canvas.Pen.Color := clBlack; PaintBox1.Canvas.MoveToRoundAmpcosi30pi,Roun
dAmpsini30pi;
PaintBox1.Canvas.LineToRoundAmpcosi30pi,Roun dAmpsini30pi;
End; End;
