DESCRIPTION:

EZDQueue is the graphical representation of a queue. This drawing is handled as an EZDObject, in which x is the most left and y the middle axis' coordinate. The bar, itself an EZDObject, is representing the amount of tasks waiting inside the queue.
Constructors:

EZDQueue();

EZDQueue(Param *param);

EZDQueue(int x, int y, int width = WIDTH, int heigth = HEIGTH, int tail = TAIL);

EZDQueue(const CNString &name, int x, int y, int width = WIDTH, int heigth = HEIGTH,

int tail = TAIL);

Initializes an EZDQueue as an EZDObject (default object name : "queue" ) inside the current drawing at the coordinates (x,y) ( default value (0,0) ). Width ( 100 pixels ) and heigth ( 20 pixels ) are the queue body's rectangle size measured in pixels, tail ( 20 pixels ) the tail's length.

In addition to the member functions required by CNCL, EZDQueue provides:

int left() const;

int rigth() const;

int upper() const;

int lower() const;

Returns the left, right, upper or lower coordinate of the object queue inside the current drawing.

virtual void redraw();

Redraws this queue in the current drawing.

int length() const;

int get_length() const;

void length(int l);

void set_length(int l);

Get/set length of the queue-bar.

void color(const CNString &c);

Sets the color of the queue-bar to c and redraws the queue.
