Problem u JBuilder-u 4

Imam problem u JBuilder-u u Windowsu. Do sada nisam imao iskustva sa njim i nije mi jasno zasto kada crtam/dodajem neku kontrolu na formu ona se odmah razvuce po celoj formi i nikako ne mogu da je smanjim a kad dodam jos kontrola one se prepolove tako da je cela forma puna i mora uvek da je puna. Odnosno nikako ne mogu da dodajem kontrole kao u VB-u ili C#-u. Da li to tako treba ili ...? :)

Nije to problem u JBuilderu, vec je problem u Java AWT kontrolama, jer AWT nema fixed polozaj i velicinu,
vec se odredjuje prema ostalim kontrolama. Nista drugo ti ne preostaje nego da koristis panele, koje ces
prvo lepo da rasporedis a zatim da u te panele postavljas dugmice, forme i slicno.. Tek tako mozes da uradis
ono sto si hteo..

Poz, alex.

Znaci li to da ne postoji nacin da kontrole postavljam onako kako se to radi u VB-u

---

Jesi li ti procitao sta sam ja napisao gore? Mozes da postavljas kontrole, ali to zahteva malo vise
"postavljanja", odnosno vise kontrola nego u VB-u...

E a mozes da korisits onaj ..khm ne mogu da se sjetim koji je to property ali ima u nazivu GRID i onda mozes da slazes komponente.

Cini mi se da je najjednostavnije da Layout forme stavis na null i onda mozes da trpas kontrole gde god hoces ali ni Layout-i nisu dzaba izmisljeni ... vidi se cemu sluze kad resize-ujes formu ... da, radi, probao sam ...

---

E da ako neko nadje prob kod ovog mog programa???
Ovako kao sto vidite program radi sledece:
Unesete podatke u txt field i pritisnete unesi on ce uneti podatke i onda unesete tako jedno 4 komada...
I kad bi upisali neku podatak od onih sto ste uneli dobili bi sve informacije o njemu.
Uglavnom on ne trazi nego prikaze samo provog sto ste uneli ako me razumete sta hocu da kazem...

E hvala tweeester-u stvarno radi samo nisam shvatio sta si hteo da kazes oko resize-ovanja forme.

---

Pa ako nemas layout manager i maximizujes formu kontrole ostanu gde su bile (fiksna pozicija) a desno i dole ti zvrji prazan prostor a ako stavis neki dobar layout manager controle se rasporede po celoj formi.

Ma cool je GBC(GridBagLayout) samo sto moras da se zajebavas sa postavljanjem...
