[SOLVED] new2java- gettext settext

**obdi** · 07-12-2008, 11:27 AM

Code i wrote for ClickPlay is to get the first hand money input into the textfield by using InputDialog, i try to put it in the ClickPlay(), when i click start, it keeps poping up the dialog box, and not reading the number to the textfield, is something wrong with the code or i need to put it to somewhere else(which i tried to put it to different places) please help

Java Code:

CASHONHAND = JOptionPane.showInputDialog("Enter The Amount You Wish To Play");
                        cashonhand = Double.parseDouble(CashOnHandNum.getText());
                        CashOnHandNum.setText("" + cashonhand);

Java Code:

private class ClickPlay implements ActionListener
	{
		public void actionPerformed(ActionEvent e)
		{       
                        CASHONHAND = JOptionPane.showInputDialog("Enter The Amount You Wish To Play");
                        cashonhand = Double.parseDouble(CashOnHandNum.getText());
                        CashOnHandNum.setText("" + cashonhand);
                    
			ActionListener Begin = new TimeStamp();
			MyTimer              = new Timer(35, Begin);
			MyTimer.start();
                        
		}
		private class TimeStamp implements ActionListener
		{
			public void actionPerformed(ActionEvent e)
			{
                            
				Action++;
                               
				if (Action < 20)
				{
					HideOne = RandomNumbers();
					HideTwo = RandomNumbers();
					HideTre = RandomNumbers();
					NumberOne.setText("" + HideOne);
					NumberTwo.setText("" + HideTwo);
					NumberTre.setText("" + HideTre);	
				}
				else
				{
					Action = 0;
					MyTimer.stop();
					
					NumberOne.setText("*");
					NumberTwo.setText("*");
					NumberTre.setText("*");
				}
			}
		}
	}

Java Code:

JTextField CashOnHandNum      = new JTextField();
String CASHONHAND;

For debugging you code, add some println() statements to it to show the values of variables as they are changing and to show control flow.

For example, what is the value of CASHONHAND on return from the JOptonPane call? You don't appear to do anything with it.

Thanks Norm,

Java Code:

 CASHONHAND = JOptionPane.showInputDialog("Enter The Amount You Wish To Play");
                        cashonhand = Integer.parseInt(CASHONHAND);
                        //cashonhand = Integer.parseInt(cashonhand.getText());
                        CashOnHandNum.setText("" + cashonhand);

so now i get value for CASHONHAND, here's my question. Why don't i need getText()? or when i use the .parse with String i don't need it? it's like a syntax?

Hey everybody,

- I make menu form(JForm) to access another form (this form use max resolution screen which computer run)
- From menu form, I load another form(JInternalFrame) into this form.
- another form have jScroolPane in JInternalFrame.

Process:
- When I run my program, scrool in another form can not functioned.

My question:
- How I must do for activating this scrool?
- I can use scrool with JDialog, but I can not using screen resolution for making display area. How I set display area JDialog?

Thank's a lot for your time.

Salam,
