I’m designing a game through Java, using swing as my GUI. NetBeans is my editor, and I’m trying to use their editor mode, however whenever I run the code, nothing appears. I tried building it into a jar, but when I run the jar nothing appears still.
Here is my code:
package kraz;
public class KrazGUI extends javax.swing.JFrame {
public KrazGUI() {
initComponents();
setVisible(true);
}
// <editor-fold defaultstate="collapsed" desc="Generated Code">
private void initComponents() {
PathOptions = new javax.swing.ButtonGroup();
InventoryOptions = new javax.swing.ButtonGroup();
Settings = new javax.swing.ButtonGroup();
GameOptions = new javax.swing.ButtonGroup();

EventField = new javax.swing.JTextPane();

Thanks again for the help here.
When I run this code under JDK1.6, the window shows just fine. Although, I had to comment out the following line which is JDK1.7 API
And I think that line is the problem. You made it a pop-up window. I would suggest to try with
Type.NORMAL.Small side-note: you should adjust your main method to trigger the UI-code on the EDT:
See the Concurrency in Swing tutorial for more information on the why.
