#define EWL_OVERLAY ( widget ) ((Ewl_Overlay *) widget)

Typecast a pointer to an Ewl_Overlay pointer.

#define EWL_OVERLAY_IS ( w ) (ewl_widget_type_is(EWL_WIDGET(w), EWL_OVERLAY_TYPE))

Returns TRUE if the widget is an Ewl_Overlay, FALSE otherwise

#define EWL_OVERLAY_TYPE "overlay"

The type name for the Ewl_Overlay widget

typedef struct Ewl_Overlay Ewl_Overlay

The overlay structure is mostly a container for holding widgets and a wrapper evas smart object.

void ewl_overlay_cb_child_resize	(	Ewl_Container *	c,
		Ewl_Widget *	w,
		int	size,
		Ewl_Orientation	o
	)

void ewl_overlay_cb_child_show	(	Ewl_Container *	emb,
		Ewl_Widget *	child
	)

void ewl_overlay_cb_configure	(	Ewl_Widget *	w,
		void *	ev_data,
		void *	user_data
	)

int ewl_overlay_init ( Ewl_Overlay * w )

initialize a overlay to default values and callbacks

Parameters:

w,:

the overlay to be initialized to default values and callbacks

Sets the values and callbacks of a overlay w to their defaults.

Ewl_Widget* ewl_overlay_new ( void )
