Constructor & Destructor Documentation

efl::gfx::stack::stack ( ::efl::eo::parent_type _p )

inlineexplicit

Constructs a new efl::gfx::stack object.

Constructs a new efl::gfx::stack object. If you want this object to be a child of another Eo object, use an efl::eo::parent expression, like the example.

Example:

efl::gfx::stack my_stack(efl::eo::parent = parent_object);

See also: stack(Eo* eo)

efl::gfx::stack::stack ( Eo * eo )

inlineexplicit

Eo Constructor.

Constructs the object from an Eo* pointer stealing its ownership.

Parameters

eo	The Eo object pointer.

efl::gfx::stack::stack ( std::nullptr_t )

inlineexplicit

nullptr_t Constructor.

Constructs an empty (null) object.

Member Function Documentation

void efl::gfx::stack::stack_below ( Efl_Gfx_Stack * below_ ) const

Stack obj immediately below below.

Objects, in a given canvas, are stacked in the order they get added to it. This means that, if they overlap, the highest ones will cover the lowest ones, in that order. This function is a way to change the stacking order for the objects.

This function is intended to be used with objects belonging to the same layer in a given canvas, otherwise it will fail (and accomplish nothing).

If you have smart objects on your canvas and obj is a member of one of them, then below must also be a member of the same smart object.

Similarly, if obj is not a member of a smart object, below must not be either.

See also: evas_object_layer_get(); evas_object_layer_set(); evas_object_stack_below()

Parameters

below the object below which to stack

void efl::gfx::stack::raise ( ) const

Raise obj to the top of its layer.

obj will, then, be the highest one in the layer it belongs to. Object on other layers won't get touched.

See also: evas_object_stack_above(); evas_object_stack_below(); evas_object_lower()

void efl::gfx::stack::stack_above ( Efl_Gfx_Stack * above_ ) const

Stack obj immediately above above.

Objects, in a given canvas, are stacked in the order they get added to it. This means that, if they overlap, the highest ones will cover the lowest ones, in that order. This function is a way to change the stacking order for the objects.

This function is intended to be used with objects belonging to the same layer in a given canvas, otherwise it will fail (and accomplish nothing).

If you have smart objects on your canvas and obj is a member of one of them, then above must also be a member of the same smart object.

Similarly, if obj is not a member of a smart object, above must not be either.

See also: evas_object_layer_get(); evas_object_layer_set(); evas_object_stack_below()

Parameters

above the object above which to stack

void efl::gfx::stack::lower ( ) const

Lower obj to the bottom of its layer.

obj will, then, be the lowest one in the layer it belongs to. Objects on other layers won't get touched.

See also: evas_object_stack_above(); evas_object_stack_below(); evas_object_raise()

short efl::gfx::stack::layer_get ( ) const

Retrieves the layer of its canvas that the given object is part of.

Returns: Number of its layer

See also: evas_object_layer_set()

Parameters

l	The number of the layer to place the object on. Must be between EVAS_LAYER_MIN and EVAS_LAYER_MAX.

void efl::gfx::stack::layer_set ( short l_ ) const

Sets the layer of its canvas that the given object will be part of.

If you don't use this function, you'll be dealing with an unique layer of objects, the default one. Additional layers are handy when you don't want a set of objects to interfere with another set with regard to stacking. Two layers are completely disjoint in that matter.

This is a low-level function, which you'd be using when something should be always on top, for example.

Warning: Be careful, it doesn't make sense to change the layer of smart objects' children. Smart objects have a layer of their own, which should contain all their children objects.

See also: evas_object_layer_get()

Parameters

l	The number of the layer to place the object on. Must be between EVAS_LAYER_MIN and EVAS_LAYER_MAX.

Efl_Gfx_Stack* efl::gfx::stack::below_get ( ) const

Get the Evas object stacked right below obj.

Returns: the #Efl_Gfx_Stack directly below obj, if any, or NULL, if none

This function will traverse layers in its search, if there are objects on layers below the one obj is placed at.

See also: evas_object_layer_get(); evas_object_layer_set(); evas_object_below_get()

Efl_Gfx_Stack* efl::gfx::stack::above_get ( ) const

Get the Evas object stacked right above obj.

Returns: the #Efl_Gfx_Stack directly above obj, if any, or NULL, if none

This function will traverse layers in its search, if there are objects on layers above the one obj is placed at.
