EOAPI void evas_obj_pointer_mode_set | ( | Evas_Object_Pointer_Mode | pointer_mode | ) |
Set pointer behavior.
This function has direct effect on event callbacks related to mouse.
If setting
is EVAS_OBJECT_POINTER_MODE_AUTOGRAB, then when mouse is down at this object, events will be restricted to it as source, mouse moves, for example, will be emitted even if outside this object area.
If setting
is EVAS_OBJECT_POINTER_MODE_NOGRAB, then events will be emitted just when inside this object area.
The default value is EVAS_OBJECT_POINTER_MODE_AUTOGRAB.

void evas_object_data_set | ( | Evas_Object * | obj, |
const char * | key, | ||
const void * | data | ||
) |
Set an attached data pointer to an object with a given string key.
obj | The object to attach the data pointer to |
key | The string key for the data to access it |
data | The pointer to the data to be attached |
This attaches the pointer data
to the object obj
, given the access string key
. This pointer will stay "hooked" to the object until a new pointer with the same string key is attached with evas_object_data_set() or it is deleted with evas_object_data_del(). On deletion of the object obj
, the pointers will not be accessible from the object anymore.
You can find the pointer attached under a string key using evas_object_data_get(). It is the job of the calling application to free any data pointed to by data
when it is no longer required.
If data
is NULL
, the old value stored at key
will be removed but no new value will be stored. This is synonymous with calling evas_object_data_del() with obj
and key
.
Example:

void* evas_object_data_get | ( | const Evas_Object * | obj, |
const char * | key | ||
) |
Return an attached data pointer on an Evas object by its given string key.
obj | The object to which the data was attached |
key | The string key the data was stored under |
NULL
if none was storedThis function will return the data pointer attached to the object obj
, stored using the string key key
. If the object is valid and a data pointer was stored under the given key, that pointer will be returned. If this is not the case, NULL
will be returned, signifying an invalid object or a non-existent key. It is possible that a NULL
pointer was stored given that key, but this situation is non-sensical and thus can be considered an error as well. NULL
pointers are never stored as this is the return value if an error occurs.
Example:
Referenced by ecore_evas_buffer_ecore_evas_parent_get(), ecore_evas_object_ecore_evas_get(), ecore_evas_object_evas_get(), edje_evas_global_perspective_get(), and edje_object_part_object_name_get().
void* evas_object_data_del | ( | Evas_Object * | obj, |
const char * | key | ||
) |
Delete an attached data pointer from an object.
obj | The object to delete the data pointer from |
key | The string key the data was stored under |
key
on obj
This will remove the stored data pointer from obj
stored under key
and return this same pointer, if actually there was data there, or NULL
, if nothing was stored under that key.
