#18320 — Netbeans "form" code is uneditable unless copy/paste into new java file

How can I modify the code automatically created by Netbeans. Some of that code appears to be uneditable.

Instead, I can copy the code, delete the form file it was in, and paste the code into a new class. But, the form disappears. At this code I have all the code, but I lose the "Design" view entirely.

Ok experts, what can I do.

The reason I want to do this is the Swing pallet (in design view) doesn't have things that I need such as modal window capabilities (jdialogs), and Jlayer capabilities (for a light box effect). Am I wrong about this.

Thank you,

NetBeans GUI Builder has traditional been one way.

Maybe you should do like most other Java GUI developers do: use the
GUI builder to learn things but write the real code yourself.

First, don't make JFrames forms.  Make JPanels.  You can add a JPanel to 
a JDialog.  I haven't played with JLayer, but a quick read-through of 
their docs makes it appear that you can reasonably expect to add a 
JPanel to one as well.

Then, when you still need to modify code for you JPanel forms, just 
don't modify the code the IDE generates.  There's an initComponents() 
method where all the non-modifiable code goes.  After initComponents() 
method is called, put your code there.

   MyJPanel() {
     initComponents();
     ... add your code here...
   }

   initComponents() {
     ... can't modify this ..
   }

Likewise, you can just add arbitrary methods to the JPanel to do 
whatever you need.

   void changeMyProperty( SomeProperty p ) {
      //  ... do stuff...
      jLabel1.setText( p.someString() );
      jTextField1 = new JTextField();
   }

   // Instance fields added by NetBeans
   private void JLabel jLabel1;
   private void JTextField jTextField1;


Basically you have to know Java programming, and then just do the 
obvious thing.  But I realize it can be hard to get started sometimes, 
so the above few hints should help you out.

Apropos of markspace's advice, the NetBeans GUI builder lets you link your 
custom methods to the events you want to handle via the properties pages for 
your screens. So you wire up those arbitrary methods to be called by the 
uneditable parts that MB provides. Best of both worlds.

Exactly; there's a related example here:

<http://stackoverflow.com/a/10468877/230513>

Also, add editor-managed panel(s) to a conventional top-level container, 
as shown here:

Anything you can't change in an appropriate Code Property?
Or the component's Customize Code dialog?

Dialog & Option Pane are under Swing Windows.

[...]

Nothing says you have to use it for _everything_.

You can't. It's created by NetBeans as determined by the properties of 
each of the palette components in the form. If you start making ad hoc 
changes to the code the relationship between the form and the code will 
be broken.

NetBeans provides you with many facilities to modify the code which is 
generated. Much of the functionality of the component is set in the 
Properties window for that component. The most flexible customization is 
in available in the "Code" tab of the Properties window. Here you can 
enter your own code at specific points during the 
construction/initialization steps of the component.

Of course, by doing this you have explicitly broken the relationship 
between the form and the Java code created from it.

Look at all the properties of the component and see if any of them can 
do what you require.

If this is related to you other question regarding modal dialogs, then I 
would recommend you start here: 
http://docs.oracle.com/javase/tutorial/uiswing/components/dialog.html

The simplest modal dialog is the JOptionPane.

Otherwise you can create your own JDialog. This might be in the main 
GUI, as the "Other Components" section of the form, or a separate class 
auto-created by the "new JDialog form". A JDialog in the form editor 
does have the modal property, which is a toggle button in the main 
Properties for the object. I have no knowledge of JLayer, but you can 
probably do what you want via the Properties/Code tab of whatever 
component in the form is most suitable.
