TUTORIAL PANEL TANGGAL
 (By Mieftahul ‘ulum Anak RpL 1 SMK Negeri 3 Banjar)
Berikut adalah langkah – langkah cara membuat panel tanggal pada Netbeans 6.9.1.
Langkah pertama:
bagian  interface
1.       Buat projek baru
2.       Jjframe form > beri nama tanggal
3.       Set tittle jframe form  baru , kasih nama seterah anda.
4.       Buat seperti gambar dibawah ini.
 

5.       Pasang jpanel, kemudian klik kanan pada jpanel property > border > line border.
6.       Ganti model pada combo box tangal 1 sampai 31, combo box bulan diisi januari sampai desember, sedang combo tahun kita kosongkan saja.
7.       Pasang 3 combo box dalam jpanel seperti gambar diatas dimana combo box pertama sebagai tanggal, Kedua sebagai bulan, ketiga adalah tahun.
8.       Ubah nama combo box pertama menjadi cmb_D, kedua menjadi cmb_M, ketiga menjadi cmb_Y.
Langkah kedua :
bagian source coding
1.       buat fungsi untuk menampilkan tahun pada combo box tahun:
private void isicmbtahun(){
        java.util.Calendar cal = java.util.Calendar.getInstance();
        int awal = cal.get(cal.YEAR);
        Integer[] isi = new Integer[60];
        for(int i = 0; i < 60 ; i++){
            isi[i] = awal - i;
        }
        DefaultComboBoxModel dcm = new DefaultComboBoxModel(isi);
        cmb_y.setModel(dcm);
    }


2.       buat fungsi untuk menampilkan tanggal :

private void isicmbtanggal(){
        int awal = 1;
        Integer[] isi = new Integer[31];
        for(int i = 0; i < 31; i++ ){
            isi[i] = awal + i;
        }
        DefaultComboBoxModel ycm = new DefaultComboBoxModel(isi);
        cmb_d.setModel(ycm);
    }
3.       buat fungsi untuk validasi tanggal :

private void validasitanggal(){
        int d = Integer.parseInt(cmb_d.getSelectedItem().toString());
        int m = cmb_m.getSelectedIndex();
        int y = Integer.parseInt(cmb_y.getSelectedItem().toString());
        if(y % 4 == 0){
            max[1] = 29;
        } else {
            max[1] = 28;
        }
        if(d > max[m]){
            cmb_d.setSelectedItem(max[m]);
        }
    }

4.       klik kanan cmb_d > event > item > Item State Changed
private void cmb_dItemStateChanged(java.awt.event.ItemEvent evt) {
 // TODO add your handling code here:
        validasitanggal();
  }
5.       klik kanan cmb_m > event > item > Item State Changed
private void cmb_mItemStateChanged(java.awt.event.ItemEvent evt) {
        // TODO add your handling code here:
        validasitanggal();
    }
6.       klik kanan cmb_y > event > item > Item State Changed
 private void cmb_yItemStateChanged(java.awt.event.ItemEvent evt) {
        // TODO add your handling code here:
        validasitanggal();
    }

}


Langkah ketiga :
Buat library
1.       new project > java class library
2.       beri nama project (library_ku)
3.       buat jpanel baru beri nama “tanggal”
4.       copy paste cmb_D, cmb_M, cmb_Y dari project sebelumnya (tanggal.java)
5.       copy paste seperti pada gambar berikut :

            
6.       copykan semua fungsi dari project sebelumnya seperti :
a.       fungsi isicmbtahun ()
b.      fungsi isismbtanggal ()
c.       fungsi sethariini ()
d.      fungsi validasi tanggal ()
e.      dan setiap even pada combo box
7.       klik kanan pada project library_ku > new > java package
8.       beri nama packagename dengan  “lbtanggal”
9.       klik kanan pada project lbtanggal > new > java class
10.   beri nama pnltanggal
11.   copy paste semua source code dari jpanel tanggal.java
12.   rubah beberapa coding seperti berikut :
i)        public class pnltgl > public class pnltgl extends javax.swing.JPanel
ii)      public tanggal1() > public pnltanggal()
13.   klik kanan pada project library_ku > clean and  bulid

Lankah keempat :
1.       klik kanan palette > create new category


2.       beri nama “my_lib”
3.       klik kanan pada my_lib > palette manager > add form jar


4.       cari dimana anda menyimpan project library_ku > folder dist > library_ku.jar
5.       pilih pnltanggal > next > pilih my_lib > finish > close
6.       buka palette > my_lib > pnltanggal
