Custom menu doesn't respond to mouseClick() attempts

javiergodas

Hi guys, so that's it. I'm testing it in Android 4.1.1, using Android 2.3.3 (default processing SDK), and I've created a Menu library that creates a vertical menu, and with a method called selectFromMenu(int x, int y), locates wich button I have pressed. Works fine in Java mode, but in Android mode, the draw_area works perfecty, but the menu buttons doesn't work. Dunno if it's a redraw() problem or a mouseClicked() detection problem, and the code look at it by yourself:

int menu_border = 0;
int menu_space = 0;
int center_x = 0, center_y = 0; 
int selected_menu = 0;
DrawArea draw_area = null;
VerticalMenuArea [] menus = new VerticalMenuArea[3];

void setup()
{
 background(255,255,255);
 size(displayWidth, displayHeight);
  draw_area = new DrawArea(); 
  String [] main_menu = {"File","Draw"};
   menus[0] = new VerticalMenuArea(0,2,main_menu,255,255,155);
  String [] file_menu = {"Exit","Save","Load","Delete","Back"};
   menus[1] = new VerticalMenuArea(1,5,file_menu,255,155,255);
  String [] draw_menu = {"Line","Square","Triangle","Circle","Back"}; 
   menus[2] = new VerticalMenuArea(2,5,draw_menu,155,255,255);
}

void draw()
{
 stroke(0);
 menu_border = displayWidth / 10;
  draw_area.receiveFromThread(selected_menu,0,displayHeight,menu_border,displayWidth);
  menus[0].receiveFromThread(selected_menu,0,displayHeight,0,menu_border);
  menus[1].receiveFromThread(selected_menu,0,displayHeight,0,menu_border);
  menus[2].receiveFromThread(selected_menu,0,displayHeight,0,menu_border);
}

void mouseClicked()
{
 if(mouseX < menu_border)
 {
  switch(selected_menu)
  {
   case 0:
    switch(menus[0].selectFromMenu(mouseX,mouseY))
    {
     case 0:
      selected_menu = 1;
     break;
     case 1:
      selected_menu = 2;
     break;
    }
   break;
   case 1:
    switch(menus[1].selectFromMenu(mouseX,mouseY))
    {
     case 0:
      exit();
     break;
     case 1:
      draw_area.saveDrawing("");
      selected_menu = 0;
     break;
     case 2:
      draw_area.loadDrawing("");
      selected_menu = 0;
     break;
     case 3:
      draw_area.changeDrawMode(4);
      selected_menu = 0;
     break;
     case 4:
      selected_menu = 0;
     break;
    }
   break;
   case 2:
    switch(menus[2].selectFromMenu(mouseX,mouseY))
    {
     case 0:
      draw_area.changeDrawMode(0);
      selected_menu = 0;
     break;
     case 1:
      draw_area.changeDrawMode(1);
      selected_menu = 0;
     break;
     case 2:
      draw_area.changeDrawMode(2);
      selected_menu = 0;
     break;
     case 3:
      draw_area.changeDrawMode(3);
      selected_menu = 0;
     break;
     case 4:
      selected_menu = 0;
     break;
    }
   break;
  }
 }
 redraw();
}

    }

    }
    else if(mouse_y > space*i && mouse_y < (space * i) + space)
    {
     selected = i;
    }
   }
  return selected;
