Probleme mit repaint() bzw. der Programstruktur

Ich habe Probleme mit der Programmstruktur eines Othello-Programmes.
Es existiert eine Applikation, ein Board und ein Frame.
Dies sind einzelne Dateien bzw. getrennte Klassen.
Nun muß das Board das Frame, das Frame das Board und die Applikation beide kennen. Eventuell benötige ich noch Klassen für die Spieler. Wie verwalte ich die Kommunikation der Klassen untereinander ?
Soll ich die Instanzen der einzelnen Klassen zentral in der Applikation verwalten ?
Ich habe bereits versucht die einzelnen Instanzen jeweils als Parameter zu übergeben. Hier ergaben sich aber Probleme mit paint() bzw. repaint().
Ich kann das Board, das Frame usw. in der Applikation verwalten wenn ich die entsprechenden Instanzen als static deklariere (Siehe unten).
Nachfolgend ein kleiner Aussschnitt aus dem Programm.

BoardPanel gibt den Mouseklick an das Frame weiter, das Frame an das Board.
Dieses setzt den Spielstein und ruft das Neuzeichnens des Frames bzw. des Panels auf.

Das sollte dir mindestens eine Warnung ausgeben. SEHR unsauber statische Variablen von den Instanzen setzen zu lassen. Die Variablennamen sind auch verwirrend.

Das mit dem repaint hängt (glaube ich) damit zusammen, dass die GUI nicht sequentiell bezüglich der Aufrufe aufgebaut wird. Ich hatte das Problem auch mal, aber es recht gräußlich gelöst. Im Internet hab ich das gefunden:

Java Quellcode

1
2
3
4
5
6
SwingUtilities.invokeLater(new Runnable(){
  public void run(){
    doGuiTasks();           // accessing Swing GUI components
    doAnotherGuiTasks();
  }
});


SwingUtilities:
http://www.dpunkt.de/java/Referenz/Das_Paket_javax.swing/170.html
Runnable:
http://www.dpunkt.de/java/Referenz/Das_Paket_java.lang/58.html

Das Problem gibt es häufiger, google mal danach.

PS: Ich habe vorrausgesetzt, dass du Swing verwendest und nicht AWT, SWT, etc.

Ja, ja, sehr unsauber. Stimmt ! Sonst hätte ich wahrscheinlich nicht so viele Probleme.
Aber wie macht man es besser ?
Die einzelnen Klassen sollen nach Möglichkeit unabhängig voneinander sein und miteinander kommunizieren. Also nicht "class Board extends Frame".
Ich verwende Swing. Stimmt !
Jetzt bitte nicht zusätzlich auch noch Threads.
Was meinst du mit "dass die GUI nicht sequentiell bezüglich der Aufrufe aufgebaut wird" ? Es gibt eine Klasse OthelloFrame und von dieser habe ich, zwecks Übersichtsgründen (Die einzelnen Dateien sollten nicht so groß werden) zwei Klassen für die beiden Panels abgespalten.

Also:
erstmal solltest du entscheiden ob du von OthelloApplication Instanzen brauchst. Wenn nein, dann brauchst du keinen Konstruktor und kannst alle Funktionen und attribute statisch machen. Wenn ja, dann mach bei den Attributen das static weg.

Quoted

class Board extends Frame
ist AWT.

Quoted

class Board extends JFrame
sollte Swing sein.

Die Variablennamen beginnt man mit einem kleinen Buchstaben. Es ist OK, wenn man den Typ im Bezeichner unterbringt. z.B.:
leftFrame
rightFrame
othelloBoard
othelloFrame
Das sorgt dafür, dass man die Variablen gut von den Klassen unterscheiden kann. Hat man einen Methodenaufruf
OthelloApplication.abc(); dann kann man nun auf einen Blick sagen, ob es sich um eine statische Methode der Klasse oder eine Methode der Instanz handelt (in diesem Fall eine statische Methode der Klasse).

Quoted

Jetzt bitte nicht zusätzlich auch noch Threads.

Threads sind nicht wirklich der Brüller in sachen Schwierigkeit. Wenn du nicht magst, dann musst du eben mal nach einer anderen Lösung googeln.
Ersetze doch testweise einfach mal dein:

Java Quellcode

1
thisFrame.repaint();

mit

Java Quellcode

1
2
3
4
5
SwingUtilities.invokeLater(new Runnable(){
  public void run(){
    thisFrame.repaint(); 
  }
});

(ungetestet, keine Garantie, funktioniert wohl eh nur bei Swing)

Du solltest dir vielleicht Gedanken machen, wie du die grafische Darstellung von der Programmlogik trennst. Das bringt enorm mehr Übersicht.

Vereinfachung

Also ich habe es mal ein bißchen vereinfacht.
Nach dem 0815-Schema in den meisten Büchern bzw. Beispielen ist jetzt:
OthelloBoard extends JPanel
Also Programmlogik und graphische Darstellung erstmal gemischt.
Probleme gibt es noch anscheinend noch beim GraphicContext mit Graphics bzw. getGraphics. Der Inhalt des JFrames wird im Panel noch einmal dargestellt. Und zwar dann wenn ein Mouseklick erfolgt daraufhin ein Stein gesetzt wird und repaint aufgerufen wird.
Diesmal einfach etwas mehr. Der gerösste Teil des Codes ist irrelevant.

OthelloApplication generiert diesmal nur ein OthelloFrame.

Hier das entsprechende JFrame. Alles uninteressant bis auf den Konstruktor und initComponents und die Zeile BoardPanel = new OthelloBoard (8). Hier wird wie bereits oben angegeben ein neues JPanel erzeugt.

Hier jetzt das Board als Erweiterung von JPanel. Das Setzen, Wegnehmen eines Steines etc. wird in GameBoard ausgeführt. Diese Klasse verwaltet das Array. OthelloBoard reagiert mittels MouseAdapter auf einen Mouseklick. Dieses führt (Ist ein Test) unmittelbar zum Setzen eines Spielsteines mittels des Aufrufes von setStone in GameBoard. Nun soll das JPanel bzw. das Board mittels repaint() neu gezeichnet werden. Dummerweise zeichnet nun das Programm den Inhalt des JFrames im JPanel.
Die Frage ist warum ? repaint() wird ja im JPanel aufgerufen.
Der Code ist nicht vollständig und nicht ausführbar.
