Constructor & Destructor Documentation

DoubleDigit()

sgl::DoubleDigit::DoubleDigit	(	Color	color,
		double	x,
		double	y,
		double	height
	)

The constructor sets the digit's color, position, and height. The digit's value is initially zero.

Parameters

color	the color of the digit
x	the x coordinate of the tens digit's lower-left corner
y	the y coordinate of the tens digit's lower-left corner
height	the height of the digits

Member Function Documentation

decrement()

void sgl::DoubleDigit::decrement

(

)

Decreases the digit's value by 1, modulo 100.

Returns

nothing

get_value()

int sgl::DoubleDigit::get_value

(

)

const

Returns the current value.

Returns

the current value.

increment()

void sgl::DoubleDigit::increment

(

)

Increases the digit's value by 1, modulo 100.

Returns

nothing

mouse_dragged()

void sgl::DoubleDigit::mouse_dragged ( double  x, double  y  )

overridevirtual

Moves the digits to a new location. The digits' sizes are unaffected.

Parameters

x	the new x coordinate of the tens digit's lower-left corner.
y	the new y coordinate of the tens digit's lower-left corner.

Returns

nothing

Reimplemented from sgl::GraphicalObject.

paint()

void sgl::DoubleDigit::paint ( ) const

overridevirtual

Draws the digits.

Implements sgl::GraphicalObject.

resize()

void sgl::DoubleDigit::resize

(

double

inc

)

Changes the height of the digits by a given amount. The digits' width changes proportionally.

Parameters

the	change in the height of the digits

Returns

nothing

set_leading_zero()

void sgl::DoubleDigit::set_leading_zero

(

bool

flag

)

Turns on or off the display of a leading zero.

Parameters

flag	if true, a leading zero is displayed; otherwise, a leading zero is not displayed.

Returns

nothing

set_value()

void sgl::DoubleDigit::set_value

(

int

value

)

Set's the value of the digits. The assigned value is modulo 100.

Parameters

value

value to assign, modulo 100

Returns

nothing

set_visible()

void sgl::DoubleDigit::set_visible

(

bool

flag

)

Makes the display visible or invisible.

Parameters

flag	if true, the digits are visible otherwise, the digits are invisible.

Returns

nothing
