how to create dynamic JLabel from netbeans

Question

I have public static variable in a JFrame. I have created a JLabel in another JFrame. I want to set the JLabel text to that variable. when I create the JLabel from netbeans, it create autogenerated code that can't be changed. I used netbeans 7.2.

I can change the JLabel using myJLabel.setText(JFrame.variableName);. but the problem is auto generated code doesn't allow me to edit above code snippet.

I would like to set the text to variable name by setting in property panel rather changing above code.

Is there a way to set the dynamic text using property panel?

P.S. - I noticed in property panel, we can set jLabel value from existing component but these components reside in same JFrame. My variable reside in another JFrame

Make the variables public from the properties panel. And moreover using autogenerated code changes the view of the app on different OS's. Also some components may be snipped out — Sri Harsha Chilakapati, Nov 04 '12 at 05:10
You could set it after the call to `initComponents` manually — MadProgrammer, Nov 04 '12 at 05:17
since I can't change autogenerated code, I remove the existing text from property panel and used setText method in JFrame constructor after ``initComponents`` method. that works properly. but if there is a way to set the text from property panel.it would be better...:) — lakshman, Nov 04 '12 at 05:17

IMO I would strongly recommend against using an IDE GUI Builder. An IDE is there to provide more productivity for those who already know the language. Now I am not saying whip out notepad and begin but rather code your UI etc manually this will give you a better grasp of the language — David Kroukamp, Nov 04 '12 at 07:12

You have two choices that I can see.

One, you simple set the text of the label after the call to initComponent

Or...

Click the label in question
Click the "Code" button on the properties sheet
Click the "..." button against "Post-Creation Code"
Enter the code you like to executed, something like myJLabel.setText(JFrame.variableName);. Remember, this code is inserted inline, so it must be well formatted and compilable

enter image description here

Which then produces something like...

private void initComponents() {    
    jLabel1 = new javax.swing.JLabel();
    jLabel1.setText("Hello");

    setLayout(new java.awt.GridBagLayout());
    add(jLabel1, new java.awt.GridBagConstraints());
}// </editor-fold>

NB- Make sure you clear the default text from the label ;)

Anything beyond the most basic of UI's, especially dynamic code, will require that you stop using the auto-generated features of almost any and all IDE's.
