 Posted: Wed Nov 17, 2004 12:30 pm Post subject: Navigation around different JFrames |
 |
|
Hi :)
I need to navigate around different JFrames.
I´ve got:
class MainView extends JFrame
class DefaultView extends MainView
class ManufacturerView extends MainView
class ArticlelView extends MainView
I always overwrite 1 to 3 Methods, wich are different at the SubViews
( Navigation,AricleInfo and so on )
Navigation are buttons, if a user clicks on a button, correct view
ough to be loaded.
My public static void main ( String[] args ) looks like this at the
moment:
| Code: |
JFrame frame = new MainView ( ControllerObject );
frame.pack ( );
frame.setSize ( 1024, 768 );
frame.setVisible ( true );
frame.show ( );
|
Within ControllerObject there are important values for the next view.
How could I get it work, that if I click a button, the correct next
view gets loaded?
I´ve tried CardLayout, but it seems not to work with JFrame:
JFrame frame = new MainView ( ControllerObjekt );
CardLayout ACardLayout = new CardLayout ( );
ACardLayout.addLayoutComponent( frame, "default" );
ACardLayout.show( frame, "default");
java.lang.IllegalArgumentException: wrong parent for CardLayout
First parameter has to be no JFrame, but I need JFrame :-/
Is there another possibility to get it work?
Thank you
Bye, Bastian

you have a bit wrong design, make your MainView extend JPanel, then you can
use CardLayout.

this.setUndecorated ( true );
this.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
this.setContentPane ( getJContentPane ( ) );
this.setVisible ( true );
I need no Frame around my Application.
I need 1024 x 768 px without any border, so I can´t use JPanel, can I?

you can:
JFrame frame = new JFrame();
frame.setBounds ( 0, 0, 1024, 768 );
frame.setResizable ( false );
frame.setName ( "POS" );
frame.setUndecorated ( true );
frame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
frame.setContentPane ( getJContentPane ( ) ); //whatever JContentPane is
frame.setVisible(true);
however I can't see from your code snippet nothing about your Views...

That´s a code snippet from my MainView extends JFrame
protected void initialize ( )
{
this.setBounds ( 0, 0, 1024, 768 );
this.setResizable ( false );
this.setName ( "POS" );
this.setUndecorated ( true );
this.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
this.setContentPane( getJContentPane ( ) );
this.setVisible ( true );
}
In my main method I got:
JFrame frame = new MainView ( ControllerObject );
And now I need something like a switch around new MainView
switch ( ControllerObject.getView )
{
case "ManufacturerView":
JFrame frame = new ManufacturerView ( .. );
break;
case "ArticleView":
..
default:
MainView ..
}
So now, how can I "run" the main method again after a click on a
button and load the correct view?

They are both a subclass of java.awt.Container, so why doesn´t it
work, if I use JFrame?

OK. Now that I have read back through this thread to (try and)
understand your question. I'll put it this way.
// make MainView a JPanel
class MainView extends JPanel
// so these three are also panels
class DefaultView extends MainView
class ManufacturerView extends MainView
class ArticlelView extends MainView
public staic void main() {
JFrame f = new JFrame();
f.getContentPane().setLayout( new CardLayout() );
....
f.getContentPane().add( "Mainview", new MainView() );
f.getContentPane().add( "DefaultView", new DefaultView() );
....
}
Now, if that does not sort your problem, you are going to need to
a) Be more precise. "it doesn't work" is a comment more likely to
get the response "flog it with a whip, it may just be lazy" than
any useful suggestions.
b) Post a *complete* short code example to give us a better feel
for what you're doing and perhaps what you are trying to achieve.

How can I access the different Views?
I haven´t got Attributes for MainView, DefaultView, and so on in my
JFrame, so how can I show another View?
At the moment, only MainView gets displayed.
And wehere and what should I assign witch object, to provide, that the
user gets another view, when he clicks on a button?
Buttons are always a field of a view:
public class ManufacturerView extends MainView
{
private JButton jButtonM1 = null;
private JButton jButtonM2 = null;
...
}
Should JFrame be assigned to MainView´s constructor?
Hope you can answer my question, or do you need more code?

Questions like these are often answered by consulting the documentation.

I´ve read the documentation, an if I my CardLayout would be an
attribute of frame, it would be no problem to sey:
frame.ACardLayout.show ( "MainView" );
But I´ve got an anonym class with your example:
JFrame f = new JFrame();
f.getContentPane().setLayout( new CardLayout() );
and so, I can´t access the CardLayout.
There for I´m asking. :(

What's an anonym?

CardLayout cl = new CardLayout();

|
f.getContentPane().setLayout( cl );

cl.show.....

Keep a reference to it, see above. And if you cannot figure
it from there, naybe you'd better post to c.l.j.help.
