Swing (Problems)

[LoganC]

I am trying to get this program to output where they put their name in a different area on the box, I have bolded the area that I feel is the issue.

Can you give us more information? Please assume that we have no idea to start with what you're trying to accomplish with your program or what it might currently be doing wrong. We're dependent on you for all these details.

[LoganC]

All I am trying to do is take a string that they are inputting in the GUI[TheirLabel], and just move it to a different part on the GUI. [NameAfterCalc]

[curmudgeon]

Please do go on... How does the user enter the String? What does the user do to tell the GUI to move the String? Where is the String initially? Where is supposed to be moved? Where exactly are you stuck? what misbehaviors are you seeing? etc... Again, explain things to us as if we don't understand your code or problem, as if we're completely ignorant.

Note that your code uses NetBeans-generated code making it hard to tell by glancing at it how its structured. We're counting on you to provide these details. A good rule of thumb here is that you should strive to put in as much effort asking your question as you'd like a volunteer to put in answering it.

[LoganC]

The user enters string in a textbox I have assigned, The string is initially where they input it in the GUI. It is supposed to be moved to a label in the bottom of the GUI. I am stuck getting the button to work. I have used the actionPerform and it still is not working. It is almost as if code is not right for me moving the code. I am trying to move what they input to a different part on the GUI

[curmudgeon]

Sorry if I'm dragging this out, but I'm still a bit unclear. First off, what is a textbox? I don't know of a Swing component with this name. Do you mean JTextField? If so, please let us know and also give us the name of the variable. Next what is in your ActionListener code? Does its actionPerformed method in fact get called? Have you added println(...) statements to test this out? Next, is the text supposed to be placed in a JLabel that is already displayed in the GUI or are you trying to create a new one and then add it to the GUI? Which label variable is it? Are you sure that it is being displayed or that it is big enough to hold your String (you can check by putting a line border around it)? Is any text at all being displayed in the JLabel?

Also, you mentioned that you've "bolded" your code to highlight a region of it, but please check this out. At least on my system, this doesn't work within code blocks. You may wish to post code snippets along with your entire program to show us in isolation regions that you think we need to concentrate on.

[LoganC]

Below is my action listener code. No text is being display at all. Text will be displayed in a jLabel that is already made.

private void NameCheckerActionPerformed(java.awt.event.ActionEvent evt) {                                            
        String TheirName = String.valueOf(TheirAnswer);
        NameAfterCalc.setText(TheirName);
 
    }

[curmudgeon]

What does TheirAnswer represent?

And again, have you added some debug code to your program? Something like:

private void NameCheckerActionPerformed(java.awt.event.ActionEvent evt) {                                            
  String TheirName = String.valueOf(TheirAnswer);
 
  // add this:
  System.out.println("inside of NameCheckerActionPerformed. String TheirName is: " + TheirName);
 
  // add this:
  NameAfterCalc.setBorder(BorderFactory.createLineBorder(Color.red));
  NameAfterCalc.setText(TheirName);
 
}

This code will be deleted later, but it's just there to test the state of your program and to see if this method is ever actually called.

[LoganC]

TheirAnswer is the JTextField where they input their name.

[curmudgeon]

TheirAnswer is the JTextField where they input their name.

Please see the edit to my post above.

So TheirAnswer is the JTextField itself? then String.valueOf(TheirAnswer) doesn't make much sense since this will return the toString() value of the JTextField which is not very useful for your purposes. Wouldn't you rather get the text held in the JTextField? Calling getText() on it here seems like a better idea, I think.

[LoganC]

I added the code you said for debugging, and I got this in the IDE:

Inside of NameCheckerActionPerformed. String TheirName is: javax.swing.JTextField[,28,38,151x28,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.synth.SynthBorder@8497904,flags=288,maximumSize=,minimumSize=,preferredSize=,caretColor=,disabledTextColor=DerivedColor(color=142,143,145 parent=nimbusDisabledText offsets=0.0,0.0,0.0,0 pColor=142,143,145,editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],selectedTextColor=DerivedColor(color=255,255,255 parent=nimbusSelectedText offsets=0.0,0.0,0.0,0 pColor=255,255,255,selectionColor=DerivedColor(color=57,105,138 parent=nimbusSelectionBackground offsets=0.0,0.0,0.0,0 pColor=57,105,138,columns=0,columnWidth=0,command=,horizontalAlignment=LEADING]

[curmudgeon]

Yep, as I thought, that's the toString() returned from your JTextField variable which is certainly not what you want. Get the JTextField's text instead by calling getText() on it.

Also, did your JLabel get a red border after the button press?

[LoganC]

TheirAnswer is the JTextField, correct. We didn't learn much about get text, is this the correct application? I am getting an error.

String TheirName = String.getText(TheirAnswer);
        NameAfterCalc.setText(TheirName);

[curmudgeon]

You call the method on the JTextField itself. To learn how to use JTextFields, please check the tutorials, Using JTextFields and the JTextField API

[LoganC]

Hmm all areas are gone, but it's still not printing out for some reason.

private void NameCheckerActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_NameCheckerActionPerformed
        String TheirName = TheirAnswer.getText();
        NameAfterCalc.setText(TheirName);

[jps]

If you use [code=java] before the code and [/code] at the end of your code, instead of [code] at the start and [/code] at the end, look how pretty.
Plus you can decorate with comments and all those pretty colors make it so easy to see.

I am trying to get this program to output where they put their name in a different area on the box, I have bolded the area that I feel is the issue.
