netbeans/java help

[javajim]

im using netbeans for my java course, i have made a basic pizza program, but want to make it better visually and funtionally(if thats a word) i was wondering if there was a way to enable a text area only if a certain check box has been selected -

i want to make it so.... when a pizza delivery check box is selected, the address text field becomes enabled to input data

would it be better to make it into radio buttons?

any help would be great

i was thinking to get my teacher to view the program and order a pizza, then actually call a pizza place to get one delivered - thats programming lol :D


heres my code.....

private void btnexitActionPerformed(java.awt.event.Ac… evt) { 
System.exit(0);
} 

private void btnsubmitActionPerformed(java.awt.event.… evt) { 
String strname = "";
String straddress = "";
String strpizzatype = "";
double cost = 0.0;
double amount = 0.0;
double delivery = 4.00;
String strquantity = " ";
double quantity = 0.0;
double garlic = 1;



strname = txtname.getText();
straddress = addressfield.getText();
strquantity = quanfield.getText();

quantity = Double.parseDouble(strquantity);



if (rdolarge.isSelected())
{ strpizzatype = "large";
cost = 10.00;
}

if (rdomedium.isSelected())
{ strpizzatype = "medium";
cost = 7.00;
}

if (rdosmall.isSelected())
{ strpizzatype = "small";
cost = 5.00;
}

if (checkdel.isSelected())
{
quantity = cost * quantity + delivery;
}

if (checkup.isSelected())
{
quantity = cost * quantity;
}

if (chkgar.isSelected())
{
quantity = garlic + cost;
}

try{
displaybox.append('\n' + "Your name : " + strname + '\n' + "Address : " + straddress + '\n' + "Pizza type : " + strpizzatype + '\n' + "Pizza cost: $ " + cost + '\n' + "Your total : $ " + quantity + '\n' + "Your Pizza will be ready in 15 minutes" );

//create a file object
File output = new File("c:\\Temp\\","app.txt");
//create a file string that will write to a text file
//on line at a time
BufferedWriter outFile = new BufferedWriter(new FileWriter
(output.getPath(), true));

outFile.write('\n' + "Your name : " + strname + '\n' + "Pizza type : " + strpizzatype + '\n' + "Pizza cost: $ " + cost + '\n' + "Your total : $ " + quantity + '\n' + "Your Pizza will be ready in 15 minutes");
//use the newLine() of the bufferedWriter class to force
//a new line to be saved in the external file
outFile.newLine();
//close file stream
outFile.close();
JOptionPane.showMessageDialog(null, "A copy of the receipt has been saved to your hard drive", " RECEIPT SAVED", JOptionPane.WARNING_MESSAGE);


}
catch(Exception e)
{
JOptionPane.showMessageDialog(null, "A copy of the receipt was unable to save to Hard drive");
}
} 

private void txtnameActionPerformed(java.awt.event.Ac… evt) { 
// TODO add your handling code here:
} 

private void checkdelActionPerformed(java.awt.event.A… evt) { 
// TODO add your handling code here:
} 

private void btnClearActionPerformed(java.awt.event.A… evt) { 
displaybox.setText("");
txtname.setText("");
quanfield.setText("");
buttonGroup2.clearSelection();
buttonGroup1.clearSelection();
buttonGroup3.clearSelection();
} 

private void jMenuItem2ActionPerformed(java.awt.event… evt) { 
System.exit(0);
} 

private void jMenuItem1ActionPerformed(java.awt.event… evt) { 
displaybox.setText("");
txtname.setText("");
quanfield.setText("");
buttonGroup2.clearSelection();
buttonGroup1.clearSelection();
buttonGroup3.clearSelection();
}

There is a setEnabled() method that all JComponent instances have (including JTextField). You could listen for events on the check box and use this method to enable/disable the text field.

thanks for that worked well, changed it to editable though

just had in my delivery checkbox code addressfield.setEditable(true)
and for the pickup addressfield.setEditable(false)

You're welcome - I'm glad you figured it out.
