Clear TextField using Button (Java)

I'm trying to clear two text boxes using the following code. It executes without error but the numbers entered in the text box do not change once the button is clicked. Any suggestions? Thanks in advance! :)

btnClear = new Button(shlTestProject, SWT.NONE); btnClear.addKeyListener(new KeyAdapter() { @Override public void keyPressed(KeyEvent e) { textBox1.setText(""); textBox2.setText(""); } }); btnClear.setBounds(240, 298, 75, 25); btnClear.setText("Clear"); textBox1= new Text(shlTestProject, SWT.BORDER); textBox1.setBounds(224, 386, 76, 21); textBox1.addVerifyListener(new VerifyListener() { public void verifyText(VerifyEvent e) { e.doit = false; //assume we don't allow it char myChar = e.character; // get the character typed if (Character.isDigit(myChar)) e.doit = true; // allow 0-9 if (myChar == '\b') { //allow backspace e.doit = true; } } });

Use a Selection Listener to deal with with the button being pressed:

btnClear.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) { textBox1.setText(""); textBox2.setText(""); } }); 

 clear.setOnClickListener(new View.OnClickListener() { @Override public void onClick (View v){ textView.setText(""); } }); 

As Alexander mentioned, implement Action Listener into your class, then simply listen if the specific button was pressed. If it was, use this code to clear the text field. TextFieldName.setText("");.

Remember, you need to trigger your action listener event by using this line of code, else it won't work. buttonName.addActionListener(this)

Have fun programming!
