Detailed Description

Class implements an integer spinbox widget for lcdgfx library.

Up/down keys change the value by a configurable step. Optional wrap mode causes overflow above the max to roll over to the min and vice-versa. Otherwise the value is clamped at the bounds.

Constructor & Destructor Documentation

LcdGfxSpinbox()

LcdGfxSpinbox::LcdGfxSpinbox	(	const NanoRect &	rect,
		int16_t	minValue,
		int16_t	maxValue,
		int16_t	value,
		int16_t	step = 1,
		bool	wrap = false
	)

Creates a spinbox widget.

Parameters

rect	screen area for the spinbox
minValue	minimum value (inclusive)
maxValue	maximum value (inclusive)
value	initial value (clamped into [min, max])
step	increment / decrement size (must be >= 1)
wrap	if true, up/down wrap around the bounds; otherwise they clamp
