## Member Function Documentation

void Clutter::Actor::allocate | ( | const ActorBox& | box,
|  | AllocationFlags | absolute_origin_changed = `ALLOCATION_NONE` |
| ) |  |  |

Called by the parent of an actor to assign the actor its size.

Should never be called by applications (except when implementing a container or layout manager).

Actors can know from their allocation box whether they have moved with respect to their parent actor. The flags parameter describes additional information about the allocation, for instance whether the parent has moved with respect to the stage, for example because a grandparent's origin has moved.

Since cluttermm 0.8:

Parameters:

  | box | New allocation of the actor, in parent-relative coordinates.
  | flags | Flags that control the allocation.

void Clutter::Actor::allocate_available_size | ( | float | x,
|  | float | y,
|  | float | available_width,
|  | float | available_height,
|  | AllocationFlags | flags = `ALLOCATION_NONE` |
| ) |  |  |

Allocates self taking into account the Clutter::Actor's preferred size, but limiting it to the maximum available width and height provided.

This function will do the right thing when dealing with the actor's request mode.

The implementation of this function is equivalent to:

|[ if (request_mode == CLUTTER_REQUEST_HEIGHT_FOR_WIDTH) { clutter_actor_get_preferred_width (self, available_height, &min_width, &natural_width); width = CLAMP (natural_width, min_width, available_width);

clutter_actor_get_preferred_height (self, width, &min_height, &natural_height); height = CLAMP (natural_height, min_height, available_height); } else { clutter_actor_get_preferred_height (self, available_width, &min_height, &natural_height); height = CLAMP (natural_height, min_height, available_height);

clutter_actor_get_preferred_width (self, height, &min_width, &natural_width); width = CLAMP (natural_width, min_width, available_width); }

box.x1 = x; box.y1 = y; box.x2 = box.x1 + available_width; box.y2 = box.y1 + available_height; clutter_actor_allocate (self, &box, flags); ]|

This function can be used by fluid layout managers to allocate an actor's preferred size without making it bigger than the area available for the container.

Since cluttermm 1.0:

Parameters:

  | x | The actor's X coordinate.

void Clutter::Actor::allocate_preferred_size | ( | AllocationFlags | absolute_origin_changed = `ALLOCATION_NONE` | ) |

Allocates the natural size of self.

This function is a utility call for Clutter::Actor implementations that allocates the actor's preferred natural size. It can be used by fixed layout managers (like Clutter::Group or so called 'composite actors') inside the ClutterActor::allocate implementation to give each child exactly how much space it requires.

This function is not meant to be used by applications. It is also not meant to be used outside the implementation of the ClutterActor::allocate virtual function.

Since cluttermm 0.8:

Parameters:

  | flags | Flags controlling the allocation.

If you want to keep around a Pango::Layout created by this function you will have to connect to the Clutter::Backend::font-changed and Clutter::Backend::resolution-changed signals, and call pango_layout_context_changed() in response to them.

Since cluttermm 1.0:

Parameters:

  | text | (allow-none) the text to set on the Pango::Layout, or `0`.

Returns:
  The opacity of the actor.

guint8 Clutter::Actor::get_paint_opacity | ( |  | ) | const

Retrieves the absolute opacity of the actor, as it appears on the stage.

This function traverses the hierarchy chain and composites the opacity of the actor with that of its parents.

Since cluttermm 0.8:

Returns:
  The actor opacity value.

bool Clutter::Actor::get_paint_visibility | ( |  | ) | const

| ) |  |  | const

Computes the preferred minimum and natural size of an actor, taking into account the actor's geometry management (either height-for-width or width-for-height).

The width and height used to compute the preferred height and preferred width are the actor's natural ones.

If you need to control the height for the preferred width, or the width for the preferred height, you should use get_preferred_width() and get_preferred_height(), and check the actor's preferred geometry management using the Clutter::Actor:request-mode property.

Gets the absolute size of an actor in pixels, taking into account the scaling factors.

If the actor has a valid allocation, the allocated size will be used. If the actor has not a valid allocation then the preferred size will be transformed and returned.

If you want the transformed allocation, see get_abs_allocation_vertices() instead.

<note>When the actor (or one of its ancestors) is rotated around the X or Y axis, it no longer appears as on the stage as a rectangle, but as a generic quadrangle; in that case this function returns the size of the smallest rectangle that encapsulates the entire quad. Please note that in this case no assumptions can be made about the relative position of this envelope to the absolute position of the actor, as returned by get_transformed_position(); if you need this information, you need to use get_abs_allocation_vertices() to get the coords of the actual quadrangle.</note>

If both the allocation and a fixed position are missing, this function will return 0.

Returns:
  The X coordinate, in pixels, ignoring any transformation (i.e. scaling, rotation).

float Clutter::Actor::get_y | ( |  | ) | const

Retrieves the Y coordinate of a Clutter::Actor.

This function tries to "do what you mean", by returning the correct value depending on the actor's state.

Reimplemented in Clutter::Cairo::Texture, Clutter::Clone, Clutter::Group, Clutter::Rectangle, Clutter::Stage, Clutter::Text, and Clutter::Texture.

void Clutter::Actor::grab_key_focus | ( |  | ) |

Sets the key focus of the Clutter::Stage including self to this Clutter::Actor.

Since cluttermm 1.0:

bool Clutter::Actor::has_clip | ( |  | ) | const

Determines whether the actor has a clip area set or not.

Since cluttermm 0.1:
  .1

Returns:
  `true` if the actor has a clip area set.

bool Clutter::Actor::has_pointer | ( |  | ) | const

Checks whether an actor contains the the pointer of a Clutter::InputDevice.

Since cluttermm 1.2:

Returns:
  `true` if the actor contains the pointer, and `false` otherwise.

void Clutter::Actor::hide | ( |  | ) |

Flags an actor to be hidden.

A hidden actor will not be rendered on the stage.

Actors are visible by default.

If this function is called on an actor without a parent, the Clutter::Actor:show-on-set-parent property will be set to `false` as a side-effect.

void Clutter::Actor::hide_all | ( |  | ) |

Calls hide() on all child actors (if any).

Since cluttermm 0.2:

virtual void Clutter::Actor::hide_all_vfunc | ( |  | ) | `[protected, virtual]`

bool Clutter::Actor::is_in_clone_paint | ( |  | ) | const

Checks whether self is being currently painted by a Clutter::Clone.

This function is useful only inside the paint virtual function implementations or within handlers for the Clutter::Actor::paint signal

This function should not be used by applications

Since cluttermm 1.0:

Returns:
  `true` if the Clutter::Actor is currently being painted by a Clutter::Clone, and `false` otherwise.

bool Clutter::Actor::is_mapped | ( |  | ) | const

bool Clutter::Actor::is_reactive | ( |  | ) | const

bool Clutter::Actor::is_realized | ( |  | ) | const

bool Clutter::Actor::is_rotated | ( |  | ) | const

Checks whether any rotation is applied to the actor.

Since cluttermm 0.6:

Returns:
  `true` if the actor is rotated.

bool Clutter::Actor::is_scaled | ( |  | ) | const

Checks whether the actor is scaled in either dimension.

Since cluttermm 0.6:

Returns:
  `true` if the actor is scaled.

bool Clutter::Actor::is_visible | ( |  | ) | const

void Clutter::Actor::lower | ( | const Glib::RefPtr< Actor >& | above | ) |

Puts self below above.

Both actors must have the same parent, and the parent must implement the Clutter::Container interface.

This function is the equivalent of Clutter::Container::lower_child().

Parameters:

  | above | A Clutter::Actor to lower below.

void Clutter::Actor::lower_bottom | ( |  | ) |

Lowers self to the bottom.

This function calls lower() internally.

void Clutter::Actor::map | ( |  | ) |

Sets the Clutter::ACTOR_MAPPED flag on the actor and possibly maps and realizes its children if they are visible.

Does nothing if the actor is not visible.

Calling this is allowed in only one case: you are implementing the Clutter::Actor::map virtual function in an actor and you need to map the children of that actor. It is not necessary to call this if you implement Clutter::Container because the default implementation will automatically map children of containers.

When overriding map, it is mandatory to chain up to the parent implementation.

Since cluttermm 1.0:

void Clutter::Actor::move_anchor_point | ( | float | anchor_x,
|  | float | anchor_y |
| ) |  |  |

Sets an anchor point for the actor, and adjusts the actor postion so that the relative position of the actor toward its parent remains the same.

Since cluttermm 0.6:

Parameters:

  | anchor_x | X coordinate of the anchor point.
  | anchor_y | Y coordinate of the anchor point.

void Clutter::Actor::move_anchor_point_from_gravity | ( | Gravity | gravity | ) |

Sets an anchor point on the actor based on the given gravity, adjusting the actor postion so that its relative position within its parent remains unchanged.

Since version 1.0 the anchor point will be stored as a gravity so that if the actor changes size then the anchor point will move. For example, if you set the anchor point to Clutter::GRAVITY_SOUTH_EAST and later double the size of the actor, the anchor point will move to the bottom right.

Since cluttermm 0.6:

Parameters:

  | gravity | Clutter::Gravity.

void Clutter::Actor::move_by | ( | float | dx,
|  | float | dy |
| ) |  |  |

Moves an actor by the specified distance relative to its current position in pixels.

This function modifies the fixed position of an actor and thus removes it from any layout management. Another way to move an actor is with an anchor point, see set_anchor_point().

Since cluttermm 0.2:

Parameters:

  | dx | Distance to move Actor on X axis.
  | dy | Distance to move Actor on Y axis.

void Clutter::Actor::push_internal | ( |  | ) |

Should be used by actors implementing the Clutter::Container and with internal children added through set_parent(), for instance:

|[ static void my_actor_init (MyActor *self) { self->priv = SELF_ACTOR_GET_PRIVATE (self);

clutter_actor_push_internal (CLUTTER_ACTOR (self));

/* calling set_parent() now will result in* the internal flag being set on a child of MyActor* /

/ * internal child: a background texture * / self->priv->background_tex = Clutter::Texture::new(); clutter_actor_set_parent (self->priv->background_tex, CLUTTER_ACTOR (self));

/ * internal child: a label * / self->priv->label = Clutter::Text::new(); clutter_actor_set_parent (self->priv->label, CLUTTER_ACTOR (self));

clutter_actor_pop_internal (CLUTTER_ACTOR (self));

/* calling set_parent() now will not result in* the internal flag being set on a child of MyActor* / } ]|

This function will be used by Clutter to toggle an "internal child" flag whenever set_parent() is called; internal children are handled differently by Clutter, specifically when destroying their parent.

Call pop_internal() when you finished adding internal children.

Nested calls to push_internal() are allowed, but each one must by followed by a pop_internal() call.

Since cluttermm 1.2:

void Clutter::Actor::queue_redraw | ( |  | ) |

Queues up a redraw of an actor and any children.

The redraw occurs once the main loop becomes idle (after the current batch of events has been processed, roughly).

Applications rarely need to call this, as redraws are handled automatically by modification functions.

This function will not do anything if self is not visible, or if the actor is inside an invisible part of the scenegraph.

Also be aware that painting is a NOP for actors with an opacity of 0

void Clutter::Actor::queue_relayout | ( |  | ) |

Indicates that the actor's size request or other layout-affecting properties may have changed.

This function is used inside Clutter::Actor subclass implementations, not by applications directly.

Queueing a new layout automatically queues a redraw as well.

Since cluttermm 0.8:

void Clutter::Actor::raise | ( | const Glib::RefPtr< Actor >& | below | ) |

Puts self above below.

Both actors must have the same parent, and the parent must implement the Clutter::Container interface

This function is the equivalent of Clutter::Container::raise_child().

Parameters:

  | below | A Clutter::Actor to raise above.

void Clutter::Actor::raise_top | ( |  | ) |

Raises self to the top.

This function calls raise() internally.

void Clutter::Actor::realize | ( |  | ) |

Creates any underlying graphics resources needed by the actor to be displayed.

Realization means the actor is now tied to a specific rendering context (that is, a specific toplevel stage).

This function does nothing if the actor is already realized.

Because a realized actor must have realized parent actors, calling realize() will also realize all parents of the actor.

This function does not realize child actors, except in the special case that realizing the stage, when the stage is visible, will suddenly map (and thus realize) the children of the stage.

void Clutter::Actor::remove_clip | ( |  | ) |

Removes clip area from self.

void Clutter::Actor::reparent | ( | const Glib::RefPtr< Actor >& | new_parent | ) |

This function resets the parent actor of self.

It is logically equivalent to calling unparent() and set_parent(), but more efficiently implemented, ensures the child is not finalized when unparented, and emits the parent-set signal only one time.

Since cluttermm 0.2:

Parameters:

  | new_parent | The new Clutter::Actor parent.

void Clutter::Actor::set_anchor_point | ( | float | anchor_x,
|  | float | anchor_y |
| ) |  |  |

Sets an anchor point for self.

The anchor point is a point in the coordinate space of an actor to which the actor position within its parent is relative; the default is (0, 0), i.e. the top-left corner of the actor.

Since cluttermm 0.6:

Parameters:

  | anchor_x | X coordinate of the anchor point.
  | anchor_y | Y coordinate of the anchor point.

void Clutter::Actor::set_anchor_point_from_gravity | ( | ClutterGravity | gravity | ) |

Sets an anchor point on the actor, based on the given gravity (this is a convenience function wrapping set_anchor_point()).

Since version 1.0 the anchor point will be stored as a gravity so that if the actor changes size then the anchor point will move. For example, if you set the anchor point to Clutter::GRAVITY_SOUTH_EAST and later double the size of the actor, the anchor point will move to the bottom right.

Since cluttermm 0.6:

Parameters:

  | gravity | Clutter::Gravity.

void Clutter::Actor::set_clip | ( | float | xoff,
|  | float | yoff,
|  | float | width,
|  | float | height |
| ) |  |  |

Sets clip area for self.

The clip area is always computed from the upper left corner of the actor, even if the anchor point is set otherwise.

Since cluttermm 0.6:

Parameters:

  | xoff | X offset of the clip rectangle.
  | yoff | Y offset of the clip rectangle.
  | width | Width of the clip rectangle.
  | height | Height of the clip rectangle.

void Clutter::Actor::set_depth | ( | float | depth | ) |

Sets the Z coordinate of self to depth.

The unit used by depth is dependant on the perspective setup. See also Clutter::Stage::set_perspective().

Parameters:

  | depth | Z co-ord.

void Clutter::Actor::set_fixed_position_set | ( | bool | is_set | ) |

Sets whether an actor has a fixed position set (and will thus be unaffected by any layout manager).

Since cluttermm 0.8:

Parameters:

  | is_set | Whether to use fixed position.

void Clutter::Actor::set_flags | ( | ActorFlags | flags | ) |

Sets flags on self.

This function will emit notifications for the changed properties

Since cluttermm 1.0:

Parameters:

  | flags | The flags to set.

void Clutter::Actor::set_geometry | ( | const Geometry& | geometry | ) |

Sets the actor's fixed position and forces its minimum and natural size, in pixels.

This means the untransformed actor will have the given geometry. This is the same as calling set_position() and set_size().

Parameters:

  | geometry | A Clutter::Geometry.

void Clutter::Actor::set_height | ( | float | height | ) |

Forces a height on an actor, causing the actor's preferred width and height (if any) to be ignored.

If height is -1 the actor will use its preferred height instead of overriding it, i.e. you can "unset" the height with -1.

This function sets both the minimum and natural size of the actor.

since: 0.2

Parameters:

  | height | Requested new height for the actor, in pixels, or -1.

void Clutter::Actor::set_name | ( | const gchar * | name | ) |

Sets the given name to self.

The name can be used to identify a Clutter::Actor.

Parameters:

  | name | Textual tag to apply to actor.

void Clutter::Actor::set_opacity | ( | guint8 | opacity | ) |

Sets the actor's opacity, with zero being completely transparent and 255 (0xff) being fully opaque.

Parameters:

  | opacity | New opacity value for the actor.

void Clutter::Actor::set_parent | ( | const Glib::RefPtr< Actor >& | parent | ) |

Sets the parent of self to parent.

The opposite function is unparent().

This function should not be used by applications, but by custom container actor subclasses.

Parameters:

  | parent | A new Clutter::Actor parent.

void Clutter::Actor::set_position | ( | float | x,
|  | float | y |
| ) |  |  |

Sets the actor's fixed position in pixels relative to any parent actor.

If a layout manager is in use, this position will override the layout manager and force a fixed position.

Parameters:

  | x | New left position of actor in pixels.
  | y | New top position of actor in pixels.

void Clutter::Actor::set_reactive | ( | bool | reactive = `true` | ) |

Sets actor as reactive.

Reactive actors will receive events.

Since cluttermm 0.6:

Parameters:

  | reactive | Whether the actor should be reactive to events.

void Clutter::Actor::set_request_mode | ( | RequestMode | mode | ) |

Sets the geometry request mode of self.

The mode determines the order for invoking get_preferred_width() and get_preferred_height()

Since cluttermm 1.2:

Parameters:

  | mode | The request mode.

void Clutter::Actor::set_rotation | ( | RotateAxis | axis,
|  | double | angle,
|  | float | x,
|  | float | y,
|  | float | z |
| ) |  |  |

Sets the rotation angle of self around the given axis.

The rotation center coordinates used depend on the value of axis: <itemizedlist> <listitem>

Clutter::X_AXIS requires y and z

</listitem> <listitem>

Clutter::Y_AXIS requires x and z

</listitem> <listitem>

Clutter::Z_AXIS requires x and y

</listitem> </itemizedlist>

The rotation coordinates are relative to the anchor point of the actor, set using set_anchor_point(). If no anchor point is set, the upper left corner is assumed as the origin.

Since cluttermm 0.8:

Parameters:

  | axis | The axis of rotation.
  | angle | The angle of rotation.
  | x | X coordinate of the rotation center.
  | y | Y coordinate of the rotation center.
  | z | Z coordinate of the rotation center.

void Clutter::Actor::set_scale | ( | double | scale_x,
|  | double | scale_y |
| ) |  |  |

Scales an actor with the given factors.

The scaling is relative to the scale center and the anchor point. The scale center is unchanged by this function and defaults to 0,0.

Since cluttermm 0.2:

Parameters:

  | scale_x | Double factor to scale actor by horizontally.
  | scale_y | Double factor to scale actor by vertically.

void Clutter::Actor::set_scale_full | ( | double | scale_x,
|  | double | scale_y,
|  | float | center_x,
|  | float | center_y |
| ) |  |  |

Scales an actor with the given factors around the given center point.

The center point is specified in pixels relative to the anchor point (usually the top left corner of the actor).

Since cluttermm 1.0:

Parameters:

  | scale_x | Double factor to scale actor by horizontally.
  | scale_y | Double factor to scale actor by vertically.
  | center_x | X coordinate of the center of the scale.
  | center_y | Y coordinate of the center of the scale.

void Clutter::Actor::set_scale_with_gravity | ( | double | scale_x,
|  | double | scale_y,
|  | Gravity | gravity |
| ) |  |  |

Scales an actor with the given factors around the given center point.

The center point is specified as one of the compass directions in Clutter::Gravity. For example, setting it to north will cause the top of the actor to remain unchanged and the rest of the actor to expand left, right and downwards.

Since cluttermm 1.0:

Parameters:

  | scale_x | Double factor to scale actor by horizontally.
  | scale_y | Double factor to scale actor by vertically.
  | gravity | The location of the scale center expressed as a compass direction.

void Clutter::Actor::set_shader | ( | const Glib::RefPtr< Shader >& | shader | ) |

Sets the Clutter::Shader to be used when rendering self.

If shader is `0` it will unset any currently set shader for the actor.

Since cluttermm 0.6:

Parameters:

  | shader | A Clutter::Shader or `0` to unset the shader.

Returns:
  `true` if the shader was successfully applied.

template <class ParamType >

void Clutter::Actor::set_shader_param | ( | const Glib::ustring & | param,
|  | const ParamType & | value |
| ) |  |  | `[inline]`

Sets the value for a named parameter of the shader applied to actor.

Since cluttermm 1.0:

Parameters:

  | param | The name of the parameter.
  | value | The value of the parameter.

void Clutter::Actor::set_shader_param_value | ( | const Glib::ustring & | param,

| ) |  |  | `[protected]`

Sets the value for a named parameter of the shader applied to actor.

Since cluttermm 1.0:

Parameters:

  | param | The name of the parameter.
  | value | The value of the parameter.

void Clutter::Actor::set_size | ( | float | width,
|  | float | height |
| ) |  |  |

Sets the actor's size request in pixels.

This overrides any "normal" size request the actor would have. For example a text actor might normally request the size of the text; this function would force a specific size instead.

If width and/or height are -1 the actor will use its "normal" size request instead of overriding it, i.e. you can "unset" the size with -1.

This function sets or unsets both the minimum and natural size.

Parameters:

  | width | New width of actor in pixels, or -1.
  | height | New height of actor in pixels, or -1.

void Clutter::Actor::set_text_direction | ( | TextDirection | text_dir | ) |

Sets the Clutter::TextDirection for an actor.

The passed text direction must not be Clutter::TEXT_DIRECTION_DEFAULT

If self implements Clutter::Container then this function will recurse inside all the children of self (including the internal ones).

Composite actors not implementing Clutter::Container, or actors requiring special handling when the text direction changes, should connect to the Object::notify signal for the Clutter::Actor:text-direction property

Since cluttermm 1.2:

Parameters:

  | text_dir | The text direction for self.

void Clutter::Actor::set_width | ( | float | width | ) |

Forces a width on an actor, causing the actor's preferred width and height (if any) to be ignored.

If width is -1 the actor will use its preferred width request instead of overriding it, i.e. you can "unset" the width with -1.

This function sets both the minimum and natural size of the actor.

since: 0.2

Parameters:

  | width | Requested new width for the actor, in pixels, or -1.

void Clutter::Actor::set_x | ( | float | x | ) |

Sets the actor's X coordinate, relative to its parent, in pixels.

Overrides any layout manager and forces a fixed position for the actor.

Since cluttermm 0.6:

Parameters:

  | x | The actor's position on the X axis.

void Clutter::Actor::set_y | ( | float | y | ) |

Sets the actor's Y coordinate, relative to its parent, in pixels.

#

Overrides any layout manager and forces a fixed position for the actor.

Since cluttermm 0.6:

Parameters:

  | y | The actor's position on the Y axis.

void Clutter::Actor::set_z_rotation_from_gravity | ( | double | angle,
|  | Gravity | gravity |
| ) |  |  |

Sets the rotation angle of self around the Z axis using the center point specified as a compass point.

For example to rotate such that the center of the actor remains static you can use Clutter::GRAVITY_CENTER. If the actor changes size the center point will move accordingly.

Since cluttermm 1.0:

Parameters:

  | angle | The angle of rotation.
  | gravity | The center point of the rotation.

bool Clutter::Actor::should_pick_paint | ( |  | ) | const

Should be called inside the implementation of the Clutter::Actor::pick virtual function in order to check whether the actor should paint itself in pick mode or not.

This function should never be called directly by applications.

Returns:
  `true` if the actor should paint its silhouette, `false` otherwise.

void Clutter::Actor::show | ( |  | ) |

Flags an actor to be displayed.

An actor that isn't shown will not be rendered on the stage.

Actors are visible by default.

If this function is called on an actor without a parent, the Clutter::Actor:show-on-set-parent will be set to `true` as a side effect.

void Clutter::Actor::show_all | ( |  | ) |

Calls show() on all children of an actor (if any).

void Clutter::Actor::transform_stage_point | ( | float | x,
|  | float | y,
|  | float & | x_out,
|  | float & | y_out |
| ) |  |  | const

This function translates screen coordinates ( x, y) to coordinates relative to the actor.

For example, it can be used to translate screen events from global screen coordinates into actor-local coordinates.

The conversion can fail, notably if the transform stack results in the actor being projected on the screen as a mere line.

The conversion should not be expected to be pixel-perfect due to the nature of the operation. In general the error grows when the skewing of the actor rectangle on screen increases.

Note:
  This function is fairly computationally intensive.
  This function only works when the allocation is up-to-date, i.e. inside of paint()

Since cluttermm 0.6:

Parameters:

  | x | X screen coordinate of the point to unproject.
  | y | Y screen coordinate of the point to unproject.
  | x_out | Return location for the unprojected x coordinance.
  | y_out | Return location for the unprojected y coordinance.

Returns:
  `true` if conversion was successful.

void Clutter::Actor::unmap | ( |  | ) |

Unsets the Clutter::ACTOR_MAPPED flag on the actor and possibly unmaps its children if they were mapped.

Calling this is allowed in only one case: you are implementing the Clutter::Actor::unmap virtual function in an actor and you need to unmap the children of that actor. It is not necessary to call this if you implement Clutter::Container because the default implementation will automatically unmap children of containers.

When overriding unmap, it is mandatory to chain up to the parent implementation.

Since cluttermm 1.0:

void Clutter::Actor::unparent | ( |  | ) |

Removes the parent of self.

This function should not be used in applications. It should be called by implementations of container actors, to dissociate a child from the container.

Since cluttermm 0.1:
  .1

void Clutter::Actor::unrealize | ( |  | ) |

Frees up any underlying graphics resources needed by the actor to be displayed.

Unrealization means the actor is now independent of any specific rendering context (is not attached to a specific toplevel stage).

Because mapped actors must be realized, actors may not be unrealized if they are mapped. This function hides the actor to be sure it isn't mapped, an application-visible side effect that you may not be expecting.

This function should not really be in the public API, because there isn't a good reason to call it. ClutterActor will already unrealize things for you when it's important to do so.

If you were using unrealize() in a dispose implementation, then don't, just chain up to ClutterActor's dispose.

If you were using unrealize() to implement unrealizing children of your container, then don't, ClutterActor will already take care of that.

If you were using unrealize() to re-realize to create your resources in a different way, then use _clutter_actor_rerealize() (inside Clutter) or just call your code that recreates your resources directly (outside Clutter).

void Clutter::Actor::unset_flags | ( | ActorFlags | flags | ) |

Unsets flags on self.

This function will emit notifications for the changed properties

Since cluttermm 1.0:

Parameters:

  | flags | The flags to unset.
