Public Member Functions
	Adafruit_GFX_Button (void)
	Construct an unconfigured button; call initButton() or initButtonUL() before drawing.
void	initButton (Adafruit_GFX *gfx, int16_t x, int16_t y, uint16_t w, uint16_t h, uint16_t outline, uint16_t fill, uint16_t textcolor, char *label, uint8_t textsize)
	Configure a button using center x/y and width/height in pixels. The graphics surface must outlive the button; at most nine label characters are stored.
void	initButtonUL (Adafruit_GFX *gfx, int16_t x1, int16_t y1, uint16_t w, uint16_t h, uint16_t outline, uint16_t fill, uint16_t textcolor, char *label, uint8_t textsize)
	Configure a button using upper-left x1/y1 and width/height in pixels. The graphics surface must outlive the button; at most nine label characters are stored.
void	drawButton (boolean inverted=false)
	Render the button, exchanging fill/text colors when inverted is true.
void	press (boolean p)
	Store the current pressed state and retain the previous state for edge queries.
boolean	contains (int16_t x, int16_t y)
	Return whether the pixel coordinate x/y lies inside the button rectangle.
boolean	isPressed ()
	Return the last state supplied to press().
boolean	justPressed ()
	Return true for a released-to-pressed transition in the last press() update.
boolean	justReleased ()
	Return true for a pressed-to-released transition in the last press() update.
