#2052 — Changing Panel view from

  To: comp.lang.java.gui
Hi all.
I hava a problem with my Gui. I have:
1 Frame with 2 panels (JPanel)
on first JPanel  I have JComboBox object

and on second panel i want to have different objects for each
JComboBox Item :(JSlider, JTable etc)  and i dont know how to do this.
I'm beginner in java

My code that works bad (creating a another Jpanel inside second JPanel
depending of choice JComboBox)


public class MainFrame extends JFrame{
         (...kod...)
             public MainFrame(){
             (...kod...)
                        //mainDesktops@MainFrame
                //1->z modelami
                mainDesktop1 = new JPanel();
                comboBox =new JComboBox();

                mainDesktop1.add(comboBox);
                comboBox.setBackground(Color.WHITE);

                for(int i=0; i<comboBoxItems.length;i++)
                        comboBox.addItem(comboBoxItems[i]);

                comboBox.addActionListener(new ActionListener(){
                        public void actionPerformed(ActionEvent eve){
                                mainDesktop2.removeAll();
                                mainDesktop2.validate();
 
mainDesktop2.add( setView(comboBox.getSelectedIndex()),BorderLayout.CENTER );
                                validate();
                        }//actionPerf
                });

                //2 -> opcje modeli
                mainDesktop2 = new JPanel();
                titleBorder2 =
BorderFactory.createLineBorder(Color.RED);
                add(mainDesktop2,BorderLayout.CENTER);
                mainDesktop2.setBackground(Color.BLACK);
                mainDesktop2.setBorder(new
javax.swing.border.TitledBorder(titleBorder2,titleBorder));


}//konstruktor


        JPanel setView(int wybor){
                JPanel pan = new JPanel();
                if (wybor==0){
                        bscLabel.setText("\n BER - probablity: \n" +
(int)(bscKanal.getProbablity()*100) +"%");
                        bscLabel.setForeground(Color.BLUE);

                        bscSlider.setMajorTickSpacing(20);
                        bscSlider.setPaintTicks(true);
                        bscSlider.setPaintLabels(true);
 
bscSlider.setBorder(BorderFactory.createLineBorder(Color.GRAY, 2));
                        bscKanal.setProbablity(bscSlider.getValue()/
100);
                        pan.add(bscLabel);
 
pan.add(bscSlider,BorderLayout.AFTER_LAST_LINE);
                }

                return pan;
        }

}//class

A CardLayout might suit this.

A good group for beginners in Java is comp.lang.java.help

>My code that works bad ..

.it compiles bad as well.  After commenting the lines
where it mentions missing code, and adding imports, 
I realised I'd have to define all the components as 
well, and stopped.

>I will be thankfull if someone show a code ..

.and usually SSCCE's* work best, for explaining
code problems.

I thought that the problem is not beginner and fit in this forum Sorry
if I'm wrong.

Ok sorry (but i post this code only for global schema and idea - it is
part of program)

Thanks a lot

An SSCCE is a great way to communicate 
the idea.  Please read the linked article.  I 
highly recommend it (not surprising, since 
I wrote it).

Short Self-Contained Compilable Example, a term coined by Andrew 
Thompson to describe the desired form of code snippets posted in newsgroups.

Not only did he write the article, he coined the term.. well done sir.

It has been said that genius is the ability to formulate clear useful
questions.  The SSCCE helps train newbies to ask such questions.
Further in the work of preparing the question, they often solve it
themselves. 

A more advanced user on formulating a question can try to predict the
various acidic withering responses and prepare defences. In preparing
those defences, often the solution pops out.

I think we must be careful to give newbies lots of leeway. The
tendency for them is to give up, play helpless or to accept the
opinion of an "expert" they are irretrievably stupid.  

Getting them to prepare an SSCCEE is a great antidote.

I agree.  It also forces them to think, which therefore eliminates alot 
of the ones who are only seeking homework answers, or who have not 
learned that GIYF.
