Problem mit CardLayout :(

[crazyTweek]

Hallo, ich habe ein kleines Problem mit meinem Programm
Ich verwende NetBeans 6.7.1 und davon auch den Designer

Nun möchte ich mit einem CardLayout immer nur ein Fenster anzeigen lassen. Dafür hab ich JPanels erzeugt und diese einem "Container"-jPanel hinzugefügt und dem Container per rechtsklick -> Set Layout -> CardLayout ausgewählt

Nun bekomme ich aber immer eine Fehlermeldung:

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: wrong parent for CardLayout
        at java.awt.CardLayout.checkLayout(CardLayout.java:384)
        at java.awt.CardLayout.next(CardLayout.java:421)

Das sind die definierten Variablen:

    private int mWidth=130;
    private int mHeight=40;
    private int yCoord=0;
    private int currentCard = 1;

und wo der Fehler auftritt:

container = new JPanel(new CardLayout());

    container.add(bonieren,"1");
    container.add(bonierKontrolle,"2");
    CardLayout cl = (CardLayout)(container.getLayout());
    cl.show(bonieren, "1"); // <- hier ist der Fehler

wäre über jegliche Antworten sehr dankbar!

cl.show(container, "1");

immer die API lesen..

/**
* Flips to the component that was added to this layout with the
* specified <code>name</code>, using <code>addLayoutComponent</code>.
* If no such component exists, then nothing happens.
* @param parent the parent container in which to do the layout
* @param name the component name
* @see java.awt.CardLayout#addLayoutComponent(java.awt.Component, java.lang.Object)
*/

 

[crazyTweek]

Danke für die schnelle Hilfe!
Der Fehler wird jetzt nicht mehr angezeigt aber nun sehe ich nur eine leere Fläche, nix zu sehen von dem Panel das sichtbar sein sollte

mfg

 

[SlaterB]

tja, Layout hängt von vielen Faktoren ab, nur ein einem vollständigen kurzen Testprogramm kann man alle erkennen

 

[crazyTweek]

Hier ist der Inspector von NetBeans, hab ich vl da was falsch gemacht?

Hänge jetzt schon geschlagene 3 Wochen an dem Problem ;(

mfg

 

[SlaterB]

auch mit diesen Informationen kann man noch diverse Dinge verstellen, z.B. irgendwo setPreferredSize,

es ist doch ganz einfach, poste einen 30zeiligen Code mit main-Methode, und alles ist sofort geklärt

 

[crazyTweek]

Das Problem ist, in Netbeans wird da soviel computercode erzeugt

Aber das dürfte soweit alles wichtige sein:

tja,
initComponents(); fehlt, bonieren usw. sind nicht definiert,

bevor man Programme verstehen, evtl. nach Fehlern untersuchen kann, muss man erstmal die Kontrolle darüber erlangen,
wenn du NetBeans für dich programmieren läßt, dann soll das dir die Fehler erklären

 

[crazyTweek]

initComponents() ist schon definiert wie alles andere auch, aber die Funktion ist soviel code und ich dachte die wäre hier unwichtig, da mir netBeans die nicht einmal bearbeiten lässt

ich behaupte nicht, dass es leicht ist, nur dass irgendwo da der Fehler liegen kann,
ohne Code kann ich ihn nicht per Gedankenkraft finden, und 500 Zeilen werde ich auch nicht durchsuchen, brauchst also nicht mehr posten

hier zum Vergleich ein Programm, das anscheinend geht

public class TestGUI
    extends JFrame
{
    private JPanel bonierKontrolle;
    private JPanel bonieren;
    private JPanel container;

    public TestGUI()
        throws Exception
    {
        bonierKontrolle = new JPanel();
        bonierKontrolle.setBackground(Color.BLUE);
        bonieren = new JPanel();
        bonieren.setBackground(Color.RED);
        container = new JPanel(new CardLayout());
        container.setBackground(Color.GREEN);
        container.add(bonieren, "1");
        container.add(bonierKontrolle, "2");
        CardLayout cl = (CardLayout)(container.getLayout());
        cl.show(container, "1");


        add(container);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(600, 600);
        setVisible(true);
    }

    public static void main(String[] args)
        throws Exception
    {

        new TestGUI();
    }
}

Wuhu, ich habs geschafft!

hatte im Inspector zu oft das CardLayout definiert.
Vielen Dank für den Denkanstoß
