source file split

[bibibi]

How do I split this source file into suit multiple files?


class Pane {
protected :
int width_, height_;
int x_, y_;
WINDOW *win_;
public:
Pane(int x, int y, int w, int h) :x_(x), y_(y), width_(w), height_(h){
win_ = newwin(h, w, y, x);
}
virtual ~Pane(){
delwin(win_);
}
virtual void draw(){
box(win_, 0, 0);
wrefresh(win_);
}
};

class BoardPane : public Pane {
public:
BoardPane(int x, int y, int w, int h) : Pane(x,y,w,h){}
void draw(){
init_pair(5, COLOR_BLUE, COLOR_BLACK);
wattron(win_, COLOR_PAIR(5));
mvwvline(win_, 1, 0, ACS_DIAMOND, height_ - 4);
mvwvline(win_, 1, width_-1, ACS_DIAMOND, height_ - 4);
mvwhline(win_, height_ - 4, 0, ACS_DIAMOND, width_);
wattroff(win_, COLOR_PAIR(5));
wrefresh(win_);
}
};

class StatPane : public Pane {
public:
StatPane(int x, int y, int w, int h) : Pane(x,y,w,h){}
void draw(){
init_pair(6, COLOR_RED, COLOR_BLACK);
wattron(win_, COLOR_PAIR(6));
box(win_, 0, 0);
mvwprintw(win_, 0, 5, "STATISTICS");
wattroff(win_, COLOR_PAIR(6));
wrefresh(win_);
} };

class Tetris {
Pane *infoPane_, *helpPane_, *nextPane_, *boardPane_, *statPane_;
public:
Tetris(){
initscr();
start_color();
cbreak();
refresh();
infoPane_ = new InfoPane(1,1,25,5);
helpPane_ = new HelpPane(1,6,25,12);
nextPane_ = new NextPane(1,18,25,5);
boardPane_ = new BoardPane(30,0,22,24);
statPane_ = new StatPane(60,3,20,20);
} ~Tetris(){
delete infoPane_;
delete helpPane_;
delete nextPane_;
delete boardPane_;
delete statPane_;
endwin();
}


void play(){
int input;
updateScreen();
input = getch();
}
void updateScreen(){
infoPane_->draw();
helpPane_->draw();
nextPane_->draw();
boardPane_->draw();
statPane_->draw();
} };
int main(){
Tetris t;
t.play();
}

Well, the obvious way would be to put each class definition into its own header file, wouldn't it?
