Edit Question
Title
Body
I'm trying to create a GUI with Swing. My problem is, I have a textfield, but I want it to have a "placeholder" (like in html). I read here and there that it can be done by overriding the paint() of the textfield. Since my code is generated I found out that I need to use the "Custom Creation Code" to override the code that was generated. Here is what I have put in the "Custom Creation Code" field new javax.swing.JTextField() { String test = super.getText(); String hint = "Username"; public void paint(Graphics g) { if ( test == null || test.length() < 1 ) { g.setColor( Color.red ); g.drawString(hint, 0, 0); } g.setColor(Color.BLACK); super.paint(g); } } This generates the following output javax.swing.JTextField username = new javax.swing.JTextField() { String test = super.getText(); String hint = "Username"; public void paint(Graphics g) { if ( test == null || test.length() < 1 ) { g.setColor( Color.red ); g.drawString(hint, 0, 0); } g.setColor(Color.BLACK); super.paint(g); } }; For now I see the textField but there is nothing in it, maybe I need to add some function onto some event, but I am not sure. I would be grateful if anyone could lend a hand. EDIT : Here is a demo of what I want to do : http://davidwalsh.name/demo/html5-placeholder.php
