Detailed Description

This class rapresents an instance of the QGLWidget Qubet. It is the game.

Version: 1.0

Author: #34

Constructor & Destructor Documentation

Qubet::Qubet ( QWidget * parent = 0 )

explicit

Create a Qubet object, which is a QGLWidget that contains the game.

Postcondition: It also start the loading of game variables and initializes the objects used in the game. To start a new instance of Qubet Game you have only to create this object, it does all for you.

Parameters

parent is a callback variable to the parent of the widget.

Qubet::~Qubet ( )

Destroy a Qubet object.

It will stop rendering, stop the game, safely stop threads and waits for them, so when this function returns you have safely deletes the Qubet instance. This is a syncronous function in order to return only when all operations for the Qubet Widget closure has been terminated.
