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

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

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 😉
