pretrazivanje JTable-a

[ trodon @ 29.01.2007. 10:07 ] @

Recimo da imam neku tabelu (obichan JTable) i da u prvoj koloni imam prezimena ljudi. Kako odraditi pretrazivanje po prezimenima (npr. kliknem na neko "find" dugme, izleti neko g**** gde cu da ukucam prezime i kada se obavi trazenje, da mi fokusira tabelu na taj red gde je trazeno ime). Ako neko zna, josh vishe bi mi znachilo da se odradi pretrazivanje kao u winamp - u. Pomagajte ljudi. Hvala unapred.

JTable samo prikazuje ono sto sadrzi njen TableModel.
Znaci pretrazivanje vrsis u modelu, a da selektujes odredjeni red iskoristi metodu JTable.changeSelection().

pozzz.

Ok, evo shta sam ispisao, ali mi ne radi, jednostavno kada kliknem na dugme "find" ne deshava se nishta...

Code:

public void actionPerformed(ActionEvent e) {
          if (e.getObject().equals(findButton)) {
                    TableModel model = clientTable.getModel();
                    for (int i = 0; i < clientTable.getRowCount(); i ++)
                              if (model.getValueAt(i, 1).toString().equals(nekoPrezimeKojeTrazim))
                                        clientTable.changeSelection(i, 1, false, false);
           }
}

U chemu je problem? Mozda ne kapiram dobra rad sa tabelama ali bio sam primoran da ga sada nauchim. Pomagajte, imam fore do 6.-tog za taj seminarski...

Ako su ti u prvoj koloni prezimena onda stavi

Code:
getValueAt(i, 0)

Postuj neko kompletnije parce koda koje moze da se pokrene pa cu ti onda moci vise pomoci.

pozzz

Evo pogledaj. Uglavnom, treba da napravim sistem od dve tabele(server i klijent), i da klijentova funkcionishe tako shto se puni sa servera. E sad, ako se user loguje, i nije bilo izmena na serveru od userovog poslednjeg logOuta, client pravi tabelu sa svog harda (iz nekog TableModela koji smo sachuvali u nekom file-u). Ako je bilo izmena, client moze da pravi celu tabelu iz serverovog modela, ili da napravi tabelu iz svog modela na hardu, a onda da trazi od servera sve izmene od poslednjeg logOuta (ovo je teze ali je i praktichnije). Imash u TableMaker-u (u mom kodu) pod komentarom kako sam ovo zamislio. Kod je malo shugaviji, ali jebiga, non stop sam neshto prepravljao i pokushavao. E, da, glavni trip je u tome da kada server shalje informacije klijentu, MORA da ih shalje u obliku stringa i to na ovu foru: petrovic:marko:178:74:23:04:1985. Kapirash, sve podatke jednog reda tabele treba da spakuje u ovo. Ako si upucen u FIX protocol bice ti jasno, mada nije ni bitno, skapiracesh kako se to sve obavlja. Ovo shto vidish u trecoj koloni (new Date()), tu u stvari treba da stoji datum kada je poslednji put neshto izmenjeno. Ako imash vremena, reshi mi problem sa upload-ovanjem clientove tabele(daj mi samo ideju ili pseudo), onaj changeSelection() od ranije, i to je to. Ako mislish da imash josh neke korisne informacije, slusham te....
Pozdrav, hvala unapred.

Dok budes kucao u JTextField-u tako ce ti se selektovati odgovarajuci red (onaj cija se prva kolona poklapa).
Nije mi jasno zasto kod tebe nije radilo.
Evo ti mali savet:
1. Koristi anonimne klase za event-e
2. Nemoj citav kod trpati u jednu klasu, vec razdvoji (npr. napravi custom TableModel i stavi ga u posebnu klasu).
3. Pogledaj malo layout manager-e (mada pretpostavljam da ti je ovo samo test klasa pa ti nije vazan izgled)

Brate, ako nisi u nekoj guzvi, jel ti nije frka da mi napishesh kako da dodam listenere za dodavanje novih vrsta i kolona (kada se na serveru doda nova vrsta (ili kolona) da klijent to automatski detektuje i doda na svojoj tabeli).
