JAVA GUI QUESTION...

[justineee]

I have two classes of GUI named LoginGui and Journalizing... I made
them in GuiGenie.. There is an okButton in the LoginGui and what I
want is when I press that button.. the LoginGui disappears and the
Journalizing GUI appears.. However, I don't have any idea on how to do
it.. Any help please?

There are two ways to answer.

* How to do it using GUIGenie:
I've no idea, you could ask the author.

* How to do it using a normal editor or IDE:
Add an ActionListener to the JButton,
in that, call loginGui.setVisible(false);
and instantiate Journalizing.

This worked for me except in calling the loginGui.setVisible(false);
Here is my code..

public static void loginFrame()
{
JFrame loginGui = new JFrame ("Log-In");
loginGui.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
loginGui.getContentPane().add (new LoginGuiTwo());
loginGui.pack();
loginGui.setVisible (true);
}

public static void main(String[] args)
{
loginFrame();
}

public void actionPerformed(ActionEvent e)
{
if (e.getSource()==loginButton)
{
loginGui.setVisible(false);
Journalizing j = new Journalizing();
j.journalFrame();
}
}

it says 'cannot find variable loginGui'. Help thanks..

public class test {

public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
final JFrame f1 = new JFrame("frame1");
f1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

f2.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JButton b = new JButton("frame2");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
f1.setVisible(false);
f2.setVisible(true);
}
});
f1.add(b);

b = new JButton("frame1");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
f2.setVisible(false);
f1.setVisible(true);
}
});
f2.add(b);

f1.setSize(400,300);
f2.setSize(400,300);

f1.setVisible(true);
}
});
}
}

private final JFrame loginGui; // see comments below

{
JFrame loginGui = new JFrame ("Log-In");

Promote loginGui from local variable in the constructor to an instance
field.

loginGui = new JFrame ("Log-In");

loginGui.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
loginGui.getContentPane().add (new LoginGuiTwo());
loginGui.pack();
loginGui.setVisible (true);
}

public static void main(String[] args)
{
loginFrame();
}

public void actionPerformed(ActionEvent e)
{
if (e.getSource()==loginButton)
{
loginGui.setVisible(false);

loginGui isn't visible here, it's out of scope.

Journalizing j = new Journalizing();
j.journalFrame();
}
}

it says 'cannot find variable loginGui'. Help thanks..

Variables defined locally in one method (or constructor) are not visible
in another method.

to make a Frame appear, the first time you need a new Frame. To make
it reappear you need setVisible(true);
