Java

[eddry 0]

nak tanya pasal java ni cam mana nak buat bila guna GUI interface dia tak selari ,

bila run dalam GUI dia berselerak jer tak selari kalu kiri kira kiri semua dia mula...

[MalaysianSecurityForce 0]

ko buat GUI pakai apa? cuba check layout yang ko gunakan. Aku recommend ko pakai SUN ONE STUDIO IDE 4 atau NetBean. Boleh download free kat www.sun.com

[eddry 0]

sekarang dah cuba guna net bean tapi lama nak install sebab pc tak power so aku guna JCreator LE sahaja

ni cth yg aku buat:

import java.awt.*;

import java.awt.event.*;

public class CutiCutiMalaysia extends EmptyFrame implements

WindowListener

{

public static void main(String arg[])

{

Frame f = new CutiCutiMalaysia("Cuti-Cuti Malaysia");

f.setSize(300,250);

f.setVisible(true);

}

public void WindowOpened(WindowEvent e){

}

public CutiCutiMalaysia(String str)

{

super(str);

addWindowListener(this);

setLayout(new FlowLayout());

setBackground(Color.yellow);

setForeground(Color.black);

Label LTitle = new Label("Cuti-Cuti Malaysia");

Label LName = new Label("Enter Name");

TextField TName = new TextField(25);

Label LLocation = new Label("Select You Location");

Button BOk = new Button("OK");

Checkbox CBHawai = new Checkbox("Hawai");

Checkbox CBParis = new Checkbox("Paris");

Checkbox CBLondon = new Checkbox("London");

add(LTitle,"Center");

add(LName,"LeftSide");

add(TName);

add(LLocation,"LeftSide");

add(BOk);

add(CBHawai);

add(CBParis);

add(CBLondon);

}

}

Ler... patut pn... ko pakai flow layout. Ko kena pandai2 imagine kalo nk pakai layout cam nih. mmg leceh sket x pakai layout nih. Aku ada contoh yg x pakai layout, tp aku x bwk source code skrg. Nanti aku post blk.

[MalaysianSecurityForce 0]

Ini contoh source code aku. Sorry kalo panjang sgt, sbb aku xder cnth yg pendek dan aku xder masa nk create blk.

setLayout(new FlowLayout());

patut la jadik cam tu..

tue flow layout punya susunan...

cuba carik camana nak guna layout2 yg lain...

aku selalu guna borderlayout, gridlayout, n flowlayout...

ada banyak lagi tapi akuselalu guna yg tue jer dah ok..

nak bagi cantik interface nie ko kena pandai2 imagine dalam kepala camna nak susunkan dia...

aku rasa baik ko try practice camna nak guna layout2...

[amarz 0]

http://java.sun.com/docs/books/tutorial/ui...yout/using.html

link nie ada tunjuk skit tentang layout manager...

sun sendiri yg sediakan tutorial nie....

aku dulu belajar layout kat sini la dulu..

pastue, kalau ko nak buat interface yg lagi best try aaa guna swing...

swing lagi menarik daripada awt cuma excution time dia slow skit...

[eddry 0]

ok aku try dulu but tq sebab bagi keterangan kat aku ni...

[MalaysianSecurityForce 0]

Senyap je ruangan ni... xder org nk tanya ker ? eddry... ko punyer projek dh setel ker ?

[wanida 0]

a'kum....saya try run coding tuh tp ader error.saya tatau la kot² saya silap cara nak run coding tuh.lgpon saya baru lg dlm java nih.saya just nak tgk cane bentuk layout yg awak kasik tu.sesaper leh tulun xplain tak?time kasih
