Function Documentation

EAPI int evas_alloc_error (void)

Return if any allocation errors have occured during the prior function.

Returns:

The allocation error flag

This function will return if any memory allocation errors occured during, and what kind they were. The return value will be one of EVAS_ALLOC_ERROR_NONE, EVAS_ALLOC_ERROR_FATAL or EVAS_ALLOC_ERROR_RECOVERED with each meaning something different.

EVAS_ALLOC_ERROR_NONE means that no errors occured at all and the function worked as expected.

EVAS_ALLOC_ERROR_FATAL means the function was completely unable to perform its job and will have exited as cleanly as possible. The programmer should consider this as a sign of very low memory and should try and safely recover from the prior functions failure (or try free up memory elsewhere and try again after more memory is freed).

EVAS_ALLOC_ERROR_RECOVERED means that an allocation error occured, but was recovered from by evas finding memory of its own it has allocated and freeing what it sees as not really usefully allocated memory. What is freed may vary. Evas may reduce the resolution of images, free cached images or fonts, trhow out pre-rendered data, reduce the complexity of change lists etc. Evas and the program will function as per normal after this, but this is a sign of low memory, and it is suggested that the program try and identify memory it doesn't need, and free it.

Example:

 extern Evas_Object *object;
 void callback (void *data, Evas *e, Evas_Object *obj, void *event_info);

 evas_object_event_callback_add(object, EVAS_CALLBACK_MOUSE_DOWN, callback, NULL);
 if (evas_alloc_error() == EVAS_ALLOC_ERROR_FATAL)
   {
     fprintf(stderr, 'ERROR: Completely unable to attach callabck. Must);
     fprintf(stderr, '       destroy object now as it cannot be used.);
     evas_object_del(object);
     object = NULL;
     fprintf(stderr, 'WARNING: Memory is really low. Cleaning out RAM.);
     my_memory_cleanup();
   }
 if (evas_alloc_error() == EVAS_ALLOC_ERROR_RECOVERED)
   {
     fprintf(stderr, 'WARNING: Memory is really low. Cleaning out RAM.);
     my_memory_cleanup();
   }

EAPI Evas_Bool evas_object_key_grab (Evas_Object * obj, const char * keyname, Evas_Modifier_Mask modifiers, Evas_Modifier_Mask not_modifiers, Evas_Bool exclusive)

Requests keyname key events be directed to obj.

Key grabs allow an object to receive key events for specific key strokes even if another object has focus. If the grab is non-exclusive then all objects that have grabs on the key will get the event, however if the grab is exclusive, no other object can get a grab on the key and only that object will get the event.

keyname is a platform dependent symbolic name for the key pressed. It is sometimes possible to convert the string to an ASCII value of the key, but not always for example the enter key may be returned as the string 'Enter'.

Typical platforms are Linux frame buffer (Ecore_FB) and X server (Ecore_X) when using Evas with Ecore and Ecore_Evas.

For a list of keynames for the Linux frame buffer, please refer to the Ecore_FB documentation.

modifiers and not_modifiers are bit masks of all the modifiers that are required and not required respectively for the new grab. Modifiers can be things such as shift and ctrl as well as user defigned types via evas_key_modifier_add.

EAPI void evas_object_lower (Evas_Object * obj)

Lower obj to the bottom of its layer.

Parameters:

obj the object to lower

EAPI Evas_Object_Pointer_Mode evas_object_pointer_mode_get (const Evas_Object * obj)

Determine how pointer will behave.

Parameters:

obj

Returns:

pointer behavior.

EAPI void evas_object_pointer_mode_set (Evas_Object * obj, Evas_Object_Pointer_Mode setting)

Set pointer behavior.

Parameters:

obj
setting desired 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.

EAPI void evas_object_raise (Evas_Object * obj)

Raise obj to the top of its layer.

Parameters:

obj the object to raise

EAPI Evas_Object* evas_object_rectangle_add (Evas * e)

Returns the list of the member objects of obj. The returned list should be freed with evas_list_free() when you no longer need it

References evas_list_append().

above the object above which to stack

EAPI void evas_object_stack_below (Evas_Object * obj, Evas_Object * below)

Stack obj immediately below below.

If obj is a member of a smart object, then below must also be a member of the same smart object.

Parameters:

obj the object to stack
below the object below which to stack

EAPI int evas_object_text_char_pos_get (const Evas_Object * obj, int pos, Evas_Coord * cx, Evas_Coord * cy, Evas_Coord * cw, Evas_Coord * ch)

Retrieve position and dimension information of a character within a text Evas_Object.

This function is used to obtain the X, Y, width and height of a the character located at pos within the Evas_Object obj. obj must be a text object as created with evas_object_text_add(). Any of the Evas_Coord parameters (cx, cy, cw, ch) may be NULL in which case no value will be assigned to that parameter.

Parameters:

obj The text object to retrieve position information for.
pos The character position to request co-ordinates for.
cx A pointer to an Evas_Coord to store the X value in (can be NULL).
cy A pointer to an Evas_Coord to store the Y value in (can be NULL).
cw A pointer to an Evas_Coord to store the Width value in (can be NULL).
ch A pointer to an Evas_Coord to store the Height value in (can be NULL).

Returns:

0 on error, 1 on success.

Parameters:

obj The evas text object to query for font information.
font A pointer to the location to store the font name in (may be NULL).
size A pointer to the location to store the font size in (may be NULL).
