jtogglebutton if then?

[ilop12]

Hey guys i just found out about net beans and im really happy because it makes everything easier. Anyway im writing a conversion gui applet, really simple, that coverts A to B with a button. Im wondering if theres a way that, if the jtogglebutton is pressed, the convert button uses formula A and if it is not pressed, it uses formula b

thanks.

edit: and if theres an easier way, whatever works for you guys. Also, is it possible to lock down everything until the user puts the right password in a password field?

Myself, I'd use JRadioButtons to switch between one conversion vs another, but be sure to link the two JRadioButtons with a ButtonGroup object -- the Sun tutorial on buttons will show you how to do this. Otherwise sure, you can use a JToggleButton for this, this toggle button cannot be the one that triggers the actual conversion. Instead you'll need a separate JButton for that.

to lock down everything until

You can disable components to keep users from using them. It there are a lot of them to turn off and on, put then in an array and run a loop.

if it is not pressed, it uses

What will make code execute if a button is NOT pressed?

Or else you can treat the button as a abstract button through an action listener.

ActionListener actionListener = new ActionListener() {
      public void actionPerformed(ActionEvent actionEvent) {
        AbstractButton abstractButton = (AbstractButton) actionEvent.getSource();
        boolean selected = abstractButton.getModel().isSelected();
        if(selected) {
          // Selection process
        }
        else {
          // non-selection process
        }
      }
    };

ok ill change my question. Using netbeans, how do i make two radio buttons and make them change the formula being used for conversion. Ill post the entire source code if that helps you guys.

use isSelected() method.

if(jToggleButton1.isSelected() == true)
{System.out.println(1 + 1);
}
else
{System.out.println(1 - 1);
}

ok ill change my question. Using netbeans, how do i make two radio buttons and make them change the formula being used for conversion. Ill post the entire source code if that helps you guys.

Best thing is that explain your question more clearly, without posting a huge code which could be lazy to read. Yea, posting the code segment, I mean the specific code segment, really helpful to answering.

Check my previous post for the solution.

[Eranga]

use isSelected() method.

if(jToggleButton1.isSelected() == true)
{System.out.println(1 + 1);
}
else
{System.out.println(1 - 1);
}

Check post #4.

[ilop12]

thank you. Is there a thanks button or equivalent? You deserve it.

edit: found it. thanks Also, using

if(jToggleButton1.isSelected() == true)
{System.out.println(1 + 1);
}
else
{System.out.println(1 - 1);
}

how do i make it change what is used in

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
//Parse degrees Celsius as a double and convert to Fahrenheit.
    //Parse degrees Celsius as a double and convert to Fahrenheit.
    int tempFahr = (int)((Double.parseDouble(text.getText())) * 4.6 + 32 - 3.14 * 2.7777);
    jLabel2.setText(tempFahr + " Zinks");

[mine0926]

I don't see any in your code where you need to use if..else statement. Anyway:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) 
{
             if(jToggleButton.isSelected == true)
             {     //Parse degrees Celsius as a double and convert to Fahrenheit.
                   int tempFahr = (int)((Double.parseDouble(text.getText())) * 4.6 + 32 - 3.14 * 2.7777);
                   jLabel2.setText(tempFahr + " Zinks");
             }
             else
             {//other operation to do.
              }               
}

Hope this help.

Goodluck,

I am just suggesting, I think you need to use parenthesis"()" to seperate your operations. I am not 100% sure but I think your operation will cause error.

EXAMPLE#1:

int newvalue = ((500 + 5) - (200 * 6))/2
[b]//this operation will return-->>547.5[/b]

this one will compute differently with:


EXAMPLE#2:

int newvalue = (((500 + 5) - 200) * 6/2
[b]//this operation will return-->>915[/b]

Goodluck. :)

I am just suggesting, I think you need to use parenthesis"()" to seperate your operations.

That govern by order of operations, or the precedence of mathematical operations.

[mine0926]

you mean ilop12's operation will return correct result even if parenthesis "()" was not used?

[Eranga]

you mean ilop12's operation will return correct result even if parenthesis "()" was not used?

Of course not. What I'm say is that in your previous post, you are explaining about the order of operations, and that's why we use parenthesis for group them accordingly. :)
