Java Forum / JavaBeans / March 2008Newbie - basic questions about Javabeans
Hello, I decided to write a simple application using Javabeans in NetBeans IDE 6.0. I created a frame with few buttons and fields. I gave a name to all fields and buttons. I switched from Design to Source and I see code like this: jButton1 = new javax.swing.JButton(); .... jButton1.setName("b_exit"); The above code cannot be changed. My questions: How I should I access object I created - I don't want to use name like jButton1 - I want to use name I assigned like b_exit. Is there any example of building simple application using JavaBeans? Which book do you recommend for learning Javabeans? Thanks, Zalek > How I should I access object I created - I don't want to use name like > jButton1 - I want to use name I assigned like b_exit. You pretty much have to use jButton1. You can change that name too. Right click on the component and select "Change variable name". > Is there any example of building simple application using JavaBeans? > Which book do you recommend for learning Javabeans? This is Swing, not Javabeans. Try to learn Swing. I recommend _Learning Java_ by O'Reilly, it's a good introduction to Java, including Swing. Once you get a handle on that, Sun's Tutorial becomes easier to read and understand. > > How I should I access object I created - I don't want to use name like > > jButton1 - I want to use name I assigned like b_exit.

In this IDE you build GUI similar way as in VB or Powerbuilder - you do not use explicitly any layout manager - IDE is doing this work for you. I created GUI, it is displayed - my question was how to programaticly change contents of this GUI. Zalek >My question was related to Javabeans IDE.

I use NetBeans 6.0.1 and I'm familiar with Matisse, the GUI builder. JavaBeans is different from NetBeans. JavaBeans is a spec. NetBeans is an IDE. Very different.

Try to learn Swing. see http://mindprod.com/jgloss/swing.html JavaBeans is an idea that never went anywhere. All that is left of it is the get/setter naming convention.

That is not fair, nor true. JavaBeans events and property sheets are used still. By those who know of them. For example, many IDEs use them that way.

I am using IDE NetBeans to create a JFrame and Java program to use this JFrame. The problem was that IDE Netbeams created names like JButton1, JButton2 etc, while I wanted to use "human" names like t_name or t_user. Using properties of the objects name was not changed, only command .setName was used. I found that mouse right click on an object changes object name - this is what I wanted.
