Constructor & Destructor Documentation

◆ TimeDisplay()

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

The constructor sets the display's color, position, and height. The time 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::TimeDisplay::decrement ( )

Decreases the time by one second.

Returns: nothing

◆ draw_separator()

void sgl::TimeDisplay::draw_separator	(	const SevenSegmentDigit &	left_ones,
		const SevenSegmentDigit &	right_tens
	)		const

protected

Draw the hours-minutes or minutes-seconds colon separator.

Parameters

left_ones	the ones digit of the left quantity
right_tens	the tens digit of the right quantity

Returns: nothing

◆ get_value()

int sgl::TimeDisplay::get_value ( ) const

Returns the current time, in seconds.

Returns: the current value.

◆ increment()

void sgl::TimeDisplay::increment ( )

Increases the time by one second.

Returns: nothing

◆ mouse_dragged()

void sgl::TimeDisplay::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

Reimplemented from sgl::GraphicalObject.

◆ move_to()

void sgl::TimeDisplay::move_to	(	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

Reimplemented from sgl::GraphicalObject.

◆ paint()

void sgl::TimeDisplay::paint ( ) const

overridevirtual

Draws the display.

Returns: nothing

Implements sgl::GraphicalObject.

◆ paint_without_leading_units()

void sgl::TimeDisplay::paint_without_leading_units ( ) const

protected

Draw the display without leading units that are zero; for example, 1:03:23 instead of 01:03:23, 4:10 instead of 00:04:10, and 3 instead of 00:00:03.

Returns: nothing

◆ resize()

void sgl::TimeDisplay::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_units()

void sgl::TimeDisplay::set_leading_units ( 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::TimeDisplay::set_value ( int sec )

Sets the time.

Parameters

sec	desired time, in seconds

Returns: nothing

◆ set_visible()

void sgl::TimeDisplay::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
