JTextField BalanceTextField = new JTextField("Balance:" + cointoss.GetBalance());
BalanceTextField.setBounds(500,170,100,15);
BalanceTextField.setBorder(null);
BalanceTextField.setOpaque(false);
BalanceTextField.setVisible(true);
CoinTossLabel.add(BalanceTextField);
CoinTossPlayButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent CoinTossPlayButtonClicked){
System.out.print('\u000C');
Balance = cointoss.GetBalance();
WagerText = WagerTextField.getText();
Wager = Integer.valueOf(WagerText);
if(Balance >= 0 + Wager){
cointoss.GetCoinResult(CoinTossGuess,Wager);
CoinTossButtonHeads.setVisible(true);
CoinTossButtonTails.setVisible(true);
} else{
System.out.println("Not Enough Funds");
}
BalanceTextField.revalidate();
}
});
This is the code for the text field and the action listener for the button I am using as part of my program. I tried to re-validate,invalidate, update and validate the text field but it wouldn't update on the screen?
您可以再次重置JTextField
值,只需使用
BalanceTextField.setText("Balance:" + cointoss.GetBalance());
