Hi Forum,
I am new to swing , netbeans . using netbeans ui components i set the button and text filed on the panel , set the button text to click ,

my intention is when i click on that button using mouse it have to show message " hai" in the text field . a simple example for my understand .

here i don't understand how can perform this action .

on the button while using the event action perform in the code it show the
following function.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:

to show the hai message in the textfield i add jTextField1.setText("hai"); as shown,

but while check this using preview design there no action takes places .

so please help me how can i perform this action using netbeans ui and action perform in code

below i am pasting the code generated by netbeans through ui.

thanks in advance

public class NewJPanel extends javax.swing.JPanel {

/** Creates new form NewJPanel */
public NewJPanel() {

Dump the NetBeans visual designer. It may look like a beginners' tool, but it isn't.

Agree with Darryl. And you dont get to learn much once you use a designer tool.
