Public Member Functions
void	ofset (int x, int y)
	Displaces the underlying rectangle by the given arguments.
void	set_drag (int to_x, int to_y)
	Flags the input as a drag event and sets it's target coordinates.
void	set_drop ()
	Flags the input as a drop event.
void	set_double_press (int x, int y)
	Flags the input as a drop event and sets it's coordinates.
void	set_drag (int from_x, int from_y, int to_x, int to_y)
	Flags the input as a drag event and sets both it's initial and it's target coordinates.
void	set_drop (int x, int y)
	Flags the input as a drop event and sets it's coordinates.
int	get_target_x () const
	Retrives x target coordinate of a drag event.
int	get_target_y () const
	Retrives y target coordinate of a drag event.
Public Member Functions inherited from bugui::button_presser
void	set_midi (uint8_t midi)
	Stores the given MIDI value.
void	set_bool (bool boolean)
	Stores the given boolean value.
void	set_double_press ()
	Flags the input as a double press event.
states	get_state () const
	Retieves the curent state.
bool	get_bool ()
	Converts the currently stored value to boolean if necesary, and returns the result.
bool	get_midi ()
	Converts the currently stored value to boolean if necesary, and returns the result.
void	clear_values ()
	Ignore currently held values and allows for overwriting them.

Additional Inherited Members
Public Types inherited from bugui::button_presser
enum	states : uint8_t { single , doubled , dragged , dropped }
Protected Types inherited from bugui::button_presser
enum class	available_values : std::uint8_t { none = 0 , boolean = 1 , midi = 2 }
Protected Member Functions inherited from bugui::rectangle
virtual bool	overlap (rectangle &other) const
	Checks whether this rectangle overlaps with another. This funciton is the bassis for handling inputs on the grid. The presser object also inherits from rectangle, and this function is called to check if a press event overlaps with a widget. If so, we can determine that this particular widget is pressed. Custom widgets can override this funciton for a more fine grained handling of presses.

Detailed Description

Adds 2D information on top of a button_presser. Meant to traverse the entire widget tree, each widget temporarly applies a coordinate offset to the paresser, reflecting their relative position in the scene.
