Stopping default behavior of events in Swing

event-handling, java, swing, user-interface

Solution

try adding `evt.consume()` after your call to `sendMessage()`

private void messageTextAreaKeyPressed(java.awt.event.KeyEvent evt) { 
 if(evt.getKeyCode() == java.awt.event.KeyEvent.VK_ENTER) {
    sendMessage();
    evt.consume();
 }
}

Problem

I have the following bit of code in a method called by clicking the send button, or pressing enter in the message text field in a piece of code. ``` // In class ChatWindow private void messageTextAreaKeyPressed(java.awt.event.KeyEvent evt) { // Event handler created by Netbeans GUI designer to call this method. if(evt.getKeyCode() == java.awt.event.KeyEvent.VK_ENTER) { sendMessage(); } } public void sendMessage() { String currentMessage = messageTextArea.getText(); addMessage("You", currentMessage); app.sendMessage(currentMessage, 1); messageTextArea.setText(""); } ``` The last bit of code blanks the text area. However, after a message is sent by pressing the enter button, rather than being empty, the text box contains a newline. My guess is that after my event handler runs, THEN the newline character is being added. How to I stop the newline being added?
