Hi again

now the problem is in the code

i've got this 2 files just for example:

/* #### FILE 1 ##### */

Code: Select all

public class Inicio extends MIDlet{
   
   Menu menu = new Menu();
   
   ...
   
   public void startApp (){
       int actuale = menu.ACTUAL;

       if(actuale == 0){
           Display display = Display.getDisplay(this);
           display.setCurrent(menu);
       }else if(actuale == 1){
           System.out.println("SUPOSTO CANVAS");
           //Display display = Display.getDisplay(this);           
           //display.setCurrent(canvas);
       }
   }
   
   ...

}

/* #### FILE 2 ##### */

Code: Select all

public class Menu extends Canvas implements Runnable{

   ...   

   Inicio iniciar = new Inicio();

   ...

   protected void keyPressed(int keyCode) {
        int gameAction = getGameAction( keyCode);
        switch (gameAction) {
                ...
            case FIRE:               
                if(MENU_SELECIONADO == 1) {
                    ACTUAL = 1;
                    iniciar.startApp();
                }
            ...
    }

}

ok that was the code
now the problem, it wont even start the app because i added the
"Inicio iniciar = new Inicio();"
but if i take ir out it works fine, but since i need the interaction between the two i really need that

can anyone exaplain to me why this doesn't work?

thanks:)

public class Inicio extends MIDlet{
   Menu menu = new Menu(this);
   
   ...
   
   public void startApp (){
       int actuale = menu.ACTUAL;

       if(actuale == 0){
           Display display = Display.getDisplay(this);
           display.setCurrent(menu);
       }else if(actuale == 1){
           System.out.println("SUPOSTO CANVAS");
           //Display display = Display.getDisplay(this);           
           //display.setCurrent(canvas);
       }
   }
   
   ...

   public void someFunction() {
    ///do what you want here
   }
}

/* #### FILE 2 ##### */

Code: Select all

public class Menu extends Canvas implements Runnable{
   ...   

   Inicio iniciar;

   ...

   public Menu(Inicio ini) {
      iniciar = ini;
   }

   protected void keyPressed(int keyCode) {
        int gameAction = getGameAction( keyCode);
        switch (gameAction) {
                ...
            case FIRE:               
                if(MENU_SELECIONADO == 1) {
                    ACTUAL = 1;
                    iniciar.someFunction();
                }
            ...
    }

}


StartApp runs when the midlet is loaded, better use some other public function. Pass the midlet object to the menu class... this will solve the problem..

In the first file dont cunstruct the menu object in the definition itself better do it this way

Code: Select all

   Menu menu;

   public void startApp (){
       menu = new Menu(this);
       int actuale = menu.ACTUAL;
       ...
   }
