Detailed Description

Model Of:

Placeable
Latch
KeyboardHandler

The semantics of a button are that of a latch. It retains information about a cell or set of cells in the property model. The button also has one or more actions to which it is bound. The user selects which action they would like to employ by holding down various modifier keys (alt, ctrl, etc.) When the user clicks on a button, the retained state is sent along with the current action to a notifier callback, where it is processed.

Constructor & Destructor Documentation

button_t	(	bool	is_default,
		bool	is_cancel,
		modifiers_t	modifier_mask,
		const button_state_descriptor_t *	first,
		const button_state_descriptor_t *	last,
		theme_t	theme
	)

Parameters:

	is_default	denotes whether or not this button is the 'default' button. On some platforms this has specific visual (e.g., pulsing) and behavioral (e.g., firing when the RETURN key is pressed) attributes.
	is_cancel	denotes whether or not this button is the default 'cancel' button. On some platforms this has specific behavioral attributes (e.g., firing when the user presses the ESC key).
	modifier_mask	represents a mask of all the possible modifier key states by which this button may change.
	first	is the first button state descriptor
	last	is one-past-the-last button state descriptor
	theme	details additional visual attributes for the widget

button_t	(	bool	is_default,
		bool	is_cancel,
		modifiers_t	modifier_mask,
		const button_state_descriptor_t *	first,
		const button_state_descriptor_t *	last,
		theme_t	theme
	)

Member Function Documentation

void display ( const any_regular_t & item )

void enable ( bool make_enabled )

Note:: (fbrereto) : this should probably take place on a per-state basis.

bool handle_key	(	key_type	key,
		bool	pressed,
		modifiers_t	modifiers
	)

bool handle_key	(	key_type	key,
		bool	pressed,
		modifiers_t	modifiers
	)

Parameters:

	key	is the relevant key for this keyboard event
	pressed	denotes whether this event is key-down or key-up
	modifiers	is an bitflag set denoting the currently-depressed modifier keys
