hi ,

I need help, I have a project that calculating the GPA

first, when the applet start ask for name and password
after that, select the department .....etc

the problem that in the init() method I write code for name and password also for
check box group to select the department but this should be appear when the stat = 1
how can i solve it ???

this my code :

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
/* <applet code="Password" width=400 height=200>
</applet>*/

public class PAS extends Applet implements ActionListener, TextListener,ItemListener{
TextField tf,tf2;
Label name;
Label password;
Label l3;
String a,a1,state="";
Button b;
int stat=0;

public void init(){

if( stat == 1)
{
CheckboxGroup cbg= new CheckboxGroup();
Checkbox cb1 = new Checkbox("Computer Scince",cbg,true) ;
cb1.addItemListener( this ) ;
add(cb1) ;

Checkbox cb2 = new Checkbox("Appl. Electricl Eng. ",cbg, false ) ;
cb2.addItemListener( this ) ;
add(cb2);
Checkbox cb3= new Checkbox("Accounting and M.I.S.",cbg, false ) ;
cb3.addItemListener( this ) ;
add(cb3) ;
}
else if ( stat == 0)
{
name = new Label("Name :") ;
add( name ) ;
tf= new TextField(20) ;
tf.addActionListener ( this ) ;
tf.addTextListener ( this ) ;
add ( tf ) ;

password = new Label("Password :") ;
add( password ) ;
tf2= new TextField(8) ;
tf2.setEchoChar('*') ;
tf2.addActionListener ( this ) ;
tf2.addTextListener ( this ) ;
add ( tf2 ) ;

l3 = new Label(" ") ;
add(l3) ;
b = new Button("OK");
b.addActionListener( this ) ;
add( b ) ;

setLayout ( new GridBagLayout()) ;

GridBagConstraints gbc = new GridBagConstraints() ;
gbc.fill = GridBagConstraints.NONE; //Set the "global" constraintes
gbc.anchor = GridBagConstraints.NORTHWEST;
gbc.weightx = 1;
gbc.weighty = 0;
addUsingGBL ( name, gbc, 0,0,1,2); //Add the componets using the
addUsingGBL ( tf, gbc,1,0,1,2); // constraints
addUsingGBL ( password, gbc, 0,2,2,2) ;
addUsingGBL ( tf2, gbc, 1,2,2,1) ;
addUsingGBL ( b, gbc, 1,3,4,2) ;
addUsingGBL ( l3, gbc, 0,3,4,2) ;
}
}
void addUsingGBL (Component comp, GridBagConstraints gbc, int x, int y, int w, int h) {
gbc.gridx = x;
gbc.gridy = y;
gbc.gridwidth = w;
gbc.gridheight = h;
add(comp, gbc) ;
}

public void actionPerformed( ActionEvent ae){
a = tf2.getText() ;
a1 = ae.getActionCommand() ;
if ( a1.equals("OK") )
{
if ( a.equals( "s19980094"))
{
stat =1;
init() ;
}
}
}
public void textValueChanged(TextEvent te)
{
}
public void itemStateChanged(ItemEvent ie){

}
}

Howdy,

I know I'm a little late here, but just wanted to offer some advice in case you plan on sticking around. Use the [CODE] tags when posting code because it will help to retain formatting and make your code easier to read. Also, consider pinpointing your code down to a particular section and post only that code...chances are you'll receive more responses as many people don't like to read through 50+ lines of code.

Thanks,
David

I ditto Dave's welcome and his comments. I don't respond to posts that don't use the CODE tags to demark and format code, and I know other Ranchers who feel the same way. Also, you'll probably get a message from the Sheriff about the JavaRanch name policy...

Sultan is an acceptable Arabic name that doesn't violate JR naming policy.
