Detailed Description

A smart object's base class definition.

Examples

evas-smart-interface.c, and evas-smart-object.c.

Field Documentation

move

void(* _Evas_Smart_Class::move) (Evas_Object *o, Evas_Coord x, Evas_Coord y)

code to be run when moving object on a canvas.

x and y will be new coordinates one applied to the object. use evas_object_geometry_get() if you need the old values, during this call. after that, the old values will be lost.

resize

void(* _Evas_Smart_Class::resize) (Evas_Object *o, Evas_Coord w, Evas_Coord h)

code to be run when resizing object on a canvas.

w and h will be new dimensions one applied to the object. use evas_object_geometry_get() if you need the old values, during this call. after that, the old values will be lost.

Examples

evas-smart-interface.c, and evas-smart-object.c.

color_set

void(* _Evas_Smart_Class::color_set) (Evas_Object *o, int r, int g, int b, int a)

code to be run when setting color of object on a canvas.

r, g, b and a will be new color components one applied to the object. use evas_object_color_get() if you need the old values, during this call. after that, the old values will be lost.

clip_set

void(* _Evas_Smart_Class::clip_set) (Evas_Object *o, Evas_Object *clip)

code to be run when setting clipper of object on a canvas.

clip will be new clipper one applied to the object. use evas_object_clip_get() if you need the old one, during this call. after that, the old (object pointer) value will be lost.

Referenced by evas_object_smart_clipped_smart_set().

clip_unset

void(* _Evas_Smart_Class::clip_unset) (Evas_Object *o)

code to be run when unsetting clipper of object on a canvas.

if you need the pointer to a previous set clipper, during this call, use evas_object_clip_get(). after that, the old (object pointer) value will be lost.

Referenced by evas_object_smart_clipped_smart_set().

interfaces

const Evas_Smart_Interface** _Evas_Smart_Class::interfaces

Evas_Smart_Interface pointers array, NULL terminated.

These will be the interfaces supported at this level for an object (parents may have others)
