Re: NetBeans 6.5 gets error when switching to design view

If a constructor contains any references to a class which will only be satisfied at run time, the reference
will not be initialized and a null pointer exception will occur.

I've recently been through the same problem. I'm glad you were able to
work this out. The behaviour of the GUI builder was explained to me by
one of the NB team.

In essence, the components you add to the GUI are beans. I had only a
very loose understanding of beans, so I went back and read the spec.

They are designed to enable higher-level composition by toolkits, and
their naming conventions allow such toolkits to instantiate and
manipulate the bean, including the getting and setting of fields, the
events that the bean reports, and the accessible methods. A BeanInfo
class can be provided to override some or all of this information.

Beans include the notion of design time and run time. The Beans utility
class includes the static method isDesignTime() which can be used to
differentiate the cases, in, for example, your constructor. If you have
runtime dependencies in any component, you should probably protect all
areas with ( ! Beans.isDesignTime() ).

That's about as far as I've gone with this.

NetBeans 6.5 gets error when switching to design view

Thanks Peter,

I retired in 2002 after 46 years of programming.  Had not written a line of code until about two weeks ago.  It is
amazing how much you can forget in  seven years.  When I think about it, I ran in the same kind of problem using
Borland's JBuilder way back then.  It is starting to come back though.

Re: Cant find librarys at compile time

Hi, I had this problem about 8 months ago. At that time, I just add
libs to my project but forgot to select the checkbox behind the libs
in the libs list.

So I can code but not to compile. if any help, try.

Is there any component that could work as a timer for Java SE? for cycle task programming

I don't know why you are looking for a "component". 

You can using javax.swing.Timer 

http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/Timer.html

or java.util.Timer

http://java.sun.com/j2se/1.5.0/docs/api/java/util/Timer.html

You might be interested in the tutorial as well:

Documentation for Making A Custom GUI Control

Thank you so much! That was exactly what I was trying to do.

It looks so simple in retrospect....perhaps I should file a feature request for greater usability
testing. ;)

RE: How to add a Swing container from another class and have it be visible?

Maybe the code would help...

Here is NewJFrame.java (creates a JFrame with a JPanel in it, which is an instantiation of TestJPanel) and
TestJPanel.java below it, comments removed for brevity's sake:

NewJFrame.java
==============
package my.gui;

public class NewJFrame extends javax.swing.JFrame {

    public NewJFrame() {
        initComponents();
    }

    @SuppressWarnings("unchecked")
    private void initComponents() {

        jPanel1 = new my.gui.TestJPanel();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        org.jdesktop.layout.GroupLayout jPanel1Layout = new org.jdesktop.layout.GroupLayout(jPanel1);
        jPanel1.setLayout(jPanel1Layout);
        jPanel1Layout.setHorizontalGroup(
            jPanel1Layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)
            .add(0, 400, Short.MAX_VALUE)
        );
        jPanel1Layout.setVerticalGroup(

Re: Keyboard Shortcut for "Call Hierarchy"

Rename vs Refactor > Rename in Grails projects

Hi,

I use the latest development NetBeans daily build and noticed that
Rename on a groovy file changes the file name itself without making
any change in the class name itself. I also noticed that Refactor >
Rename was disabled (grayed out) which made me wonder how different it
ought to be from the Rename function. Should they work alike (and
eventually change the appropriate class name in the file)? Is this a
feature being worked on? Shall I file an issue in IZ?
