Detailed Description

A graphical object representing a multi-digit seven-segment display.

Constructor & Destructor Documentation

◆ Multidigit()

sgl::Multidigit::Multidigit	(	int	n,
		Color	color,
		double	x,
		double	y,
		double	height
	)

The constructor sets the seven-segment display's number of digits, color, position, and height. The display's value is initially zero.

Parameters

n	the number of digits
color	the color of the digits
x	the x coordinate of the leading digit's lower-left corner
y	the y coordinate of the leading digit's lower-left corner
height	the height of the digits

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

Parameters

n	the number of digits
color	the color of the digits
x	the x coordinate of the leading digit's lower-left corner
y	the y coordinate of the leading digit's lower-left corner
height	the height of the digits

Member Function Documentation

◆ decrement()

void sgl::Multidigit::decrement ( )

Decreases the display's value by 1

Returns: nothing

◆ get_value()

int sgl::Multidigit::get_value ( ) const

Returns the display's current value.

Returns: the current value.

Returns the current value.

Returns: the current value.

◆ increment()

void sgl::Multidigit::increment ( )

Increases the display's value by 1

Returns: nothing

◆ mouse_dragged()

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

overridevirtual

Moves the display to a new location. The display's size is unaffected.

Parameters

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

Returns: nothing

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

Parameters

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

Returns: nothing

Reimplemented from sgl::GraphicalObject.

◆ move_to()

void sgl::Multidigit::move_to	(	double	x,
		double	y
	)

overridevirtual

Relocates the left-bottom corner of the display to the specified location. The display's size is unaffected.

Parameters

left	the x coordinate in viewport coordinates of the left-bottom corner of the display
bottom	the y coordinate in viewport coordinates of the left-bottom corner of the display

Returns: nothing

Relocates the left-bottom corner of the display to the specified location. The display's size is unaffected.

Parameters

x	the x coordinate in viewport coordinates of the left-bottom corner of the display
y	the y coordinate in viewport coordinates of the left-bottom corner of the display

Returns: nothing

Reimplemented from sgl::GraphicalObject.

◆ paint()

void sgl::Multidigit::paint ( ) const

overridevirtual

Draws the digits.

Implements sgl::GraphicalObject.

◆ resize()

void sgl::Multidigit::resize ( double inc )

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

Parameters

the	change in the height of the display

Returns: nothing

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

Parameters

the	change in the height of the digits

Returns: nothing

◆ set_leading_zeros()

void sgl::Multidigit::set_leading_zeros ( bool flag )

Turns on or off the display of leading zeros.

Parameters

flag	if true, leading zeros are displayed; otherwise, leading zeros are not displayed.

Returns: nothing

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::Multidigit::set_value ( int value )

Set's the value of the display.

Parameters

value value to assign

Returns: nothing

◆ set_visible()

void sgl::Multidigit::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
