JTextfield

Hi just a quick question here.

im doing an electronic bandit assignment and when you win the payout is added to a JTextfield called winnings.

i also have a Jbutton that allows you to transfer the winnings to the balance so you can carry on playing.

The problem im having is that once i have transfered the winnings to the balance, the JTextfield that stores the winnings amount still shows the amount of winnings i previously had instead of reseting back to 0 and starting again.

How do i go about this?

Call the JTextField.setText() method and send it "0".

sorry for being a pain but i dont have a clue what you mean. This is the code i have so far for that bit

Code :

---

 if (event.getSource()==btnTransfer){
			balance = balance + winnings;
			txtBalance.setText(balance +"");
			JOptionPane.showMessageDialog(null,"You have transferred  " +winnings+"p");
		}
 
		if (event.getSource()==btnTransfer){
			winnings =0;
		}
 
		if (event.getSource()==btnTransfer){
			winnings =0;
			btnTransfer.setEnabled(false);
			JOptionPane.showMessageDialog(null,"You now have no winnings to transfer!!!");

---

Where is the code where you change what the winnings JTextField shows? This is what you must use. Let's presume you call this variable winningsTextField, what aussie is recommending is that you simply call winningsTextField.setText("0"). That's it.

However a better way to do something like this is to separate all concerns into the model (the logical part of your program, the part concerned with winnings, accounts, and such), the view (the GUI part of your program that is concerned with displaying information and components that allow user interactions) and the control (the part of the program that responds to user interactions with GUI controls and which allows the view and the model to interact.

If done this way, you could have the model have a winnings variable and allow other classes to listen for changes in winnings value by use of listeners such as a PropertyChangeListener. If done right, any change to the value held by the winnings numeric variable will automatically be reflected in the GUI display of the winnings. It's a pretty neat trick actually.

ahhh thank you ever so much. For some reason is putting a + before and it kept adding a 0. Thats why i was getting confused.

Again thanks alot
