ClutterActorBox

typedef struct {
  ClutterUnit x1;
  ClutterUnit y1;
  ClutterUnit x2;
  ClutterUnit y2;
} ClutterActorBox;

Bounding box of an actor. The coordinates of the top left and right bottom corners of an actor. The coordinates of the two points are expressed in ClutterUnits, that is are device-independent. If you want to obtain the box dimensions in pixels, use clutter_actor_get_geometry().

enum ClutterActorFlags

clutter_actor_show ()

void                clutter_actor_show                  (ClutterActor *self);

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 "show-on-set-parent" will be set to TRUE as a side effect.

clutter_actor_show_all ()

void                clutter_actor_show_all              (ClutterActor *self);

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

Since 0.2

clutter_actor_hide ()

void                clutter_actor_hide                  (ClutterActor *self);

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 "show-on-set-parent" property will be set to FALSE as a side-effect.

clutter_actor_hide_all ()

void                clutter_actor_hide_all              (ClutterActor *self);

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

Since 0.2

clutter_actor_realize ()

void                clutter_actor_realize               (ClutterActor *self);

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

clutter_actor_unrealize ()

void                clutter_actor_unrealize             (ClutterActor *self);

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

clutter_actor_paint ()

void                clutter_actor_paint                 (ClutterActor *self);

Renders the actor to display.

This function should not be called directly by applications. Call clutter_actor_queue_redraw() to queue paints, instead.

clutter_actor_queue_redraw ()

void                clutter_actor_queue_redraw          (ClutterActor *self);

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.

clutter_actor_queue_relayout ()

void                clutter_actor_queue_relayout        (ClutterActor *self);

Indicates that the actor's size request or other layout-affecting properties may have changed. This function is used inside ClutterActor subclass implementations, not by applications directly.

Queueing a new layout automatically queues a redraw as well.

Since 0.8

clutter_actor_destroy ()

void                clutter_actor_destroy               (ClutterActor *self);

Destroys an actor. When an actor is destroyed, it will break any references it holds to other objects. If the actor is inside a container, the actor will be removed.

When you destroy a container, its children will be destroyed as well.

Note: you cannot destroy the ClutterStage returned by clutter_stage_get_default().

clutter_actor_event ()

gboolean            clutter_actor_event                 (ClutterActor *actor,
                                                         ClutterEvent *event,
                                                         gboolean capture);

This function is used to emit an event on the main stage. You should rarely need to use this function, except for synthetising events.

Since 0.6

clutter_actor_pick ()

void                clutter_actor_pick                  (ClutterActor *self,
                                                         const ClutterColor *color);

Renders a silhouette of the actor using the supplied color. Used internally for mapping pointer events to actors.

This function should never be called directly by applications.

Subclasses overiding the ClutterActor::pick() method should call clutter_actor_should_pick_paint() to decide whether to render their silhouette. Containers should always recursively call pick for each child.

Since 0.4

clutter_actor_should_pick_paint ()

gboolean            clutter_actor_should_pick_paint     (ClutterActor *self);

Utility call for subclasses overiding the pick method.

This function should never be called directly by applications.

clutter_actor_allocate ()

void                clutter_actor_allocate              (ClutterActor *self,
                                                         const ClutterActorBox *box,
                                                         gboolean absolute_origin_changed);

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 absolute_origin_changed parameter additionally indicates whether the parent has moved with respect to the stage, for example because a grandparent's origin has moved.

Since 0.8

clutter_actor_allocate_preferred_size ()

void                clutter_actor_allocate_preferred_size
                                                        (ClutterActor *self,
                                                         gboolean absolute_origin_changed);

Allocates the natural size of self.

This function is a utility call for ClutterActor implementations that allocates the actor's preferred natural size. It can be used by fixed layout managers (like ClutterGroup 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 0.8

clutter_actor_get_allocation_coords ()

void                clutter_actor_get_allocation_coords (ClutterActor *self,

                                                         gint *y_1,
                                                         gint *x_2,
                                                         gint *y_2);

Gets the layout box an actor has been assigned. The allocation can only be assumed valid inside a paint() method; anywhere else, it may be out-of-date.

An allocation does not incorporate the actor's scale or anchor point; those transformations do not affect layout, only rendering.

The returned coordinates are in pixels.

Since 0.8

clutter_actor_get_allocation_box ()

void                clutter_actor_get_allocation_box    (ClutterActor *self,
                                                         ClutterActorBox *box);

Gets the layout box an actor has been assigned. The allocation can only be assumed valid inside a paint() method; anywhere else, it may be out-of-date.

An allocation does not incorporate the actor's scale or anchor point; those transformations do not affect layout, only rendering.

Since 0.8

clutter_actor_get_allocation_geometry ()

void                clutter_actor_get_allocation_geometry
                                                        (ClutterActor *self,
                                                         ClutterGeometry *geom);

Gets the layout box an actor has been assigned. The allocation can only be assumed valid inside a paint() method; anywhere else, it may be out-of-date.

An allocation does not incorporate the actor's scale or anchor point; those transformations do not affect layout, only rendering.

The returned rectangle is in pixels.

Since 0.8

clutter_actor_get_allocation_vertices ()

void                clutter_actor_get_allocation_vertices
                                                        (ClutterActor *self,
                                                         ClutterActor *ancestor,
                                                         ClutterVertex verts[4]);

Calculates the transformed coordinates of the four corners of the actor in the plane of ancestor. The returned vertices relate to the ClutterActorBox coordinates as follows:

If ancestor is NULL the ancestor will be the ClutterStage. In this case, the coordinates returned will be the coordinates on the stage before the projection is applied. This is different from the behaviour of clutter_actor_get_abs_allocation_vertices().

Since 0.6

clutter_actor_get_preferred_size ()

void                clutter_actor_get_preferred_size    (ClutterActor *self,
                                                         ClutterUnit *min_width_p,

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 clutter_actor_get_preferred_width() and clutter_actor_get_preferred_height(), and check the actor's preferred geometry management using the "request-mode" property.

Since 0.8

clutter_actor_get_preferred_width ()

void                clutter_actor_get_preferred_width   (ClutterActor *self,

Computes the requested minimum and natural widths for an actor, optionally depending on the specified height, or if they are already computed, returns the cached values.

An actor may not get its request - depending on the layout manager that's in effect.

A request should not incorporate the actor's scale or anchor point; those transformations do not affect layout, only rendering.

Since 0.8

clutter_actor_get_preferred_height ()

Computes the requested minimum and natural heights for an actor, or if they are already computed, returns the cached values.

An actor may not get its request - depending on the layout manager that's in effect.

A request should not incorporate the actor's scale or anchor point; those transformations do not affect layout, only rendering.

                                                         gboolean is_set);

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

Since 0.8

clutter_actor_get_fixed_position_set ()

gboolean            clutter_actor_get_fixed_position_set
                                                        (ClutterActor *self);

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

Since 0.8

clutter_actor_set_geometry ()

void                clutter_actor_set_geometry          (ClutterActor *self,
                                                         const ClutterGeometry *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 clutter_actor_set_position() and clutter_actor_set_size().

clutter_actor_get_geometry ()

void                clutter_actor_get_geometry          (ClutterActor *self,
                                                         ClutterGeometry *geometry);

Gets the size and position of an actor relative to its parent actor. This is the same as calling clutter_actor_get_position() and clutter_actor_get_size(). It tries to "do what you mean" and get the requested size and position if the actor's allocation is invalid.

clutter_actor_set_size ()

void                clutter_actor_set_size              (ClutterActor *self,
                                                         gint width,
                                                         gint 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.

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.

clutter_actor_get_position ()

void                clutter_actor_get_position          (ClutterActor *self,

Since 0.2

clutter_actor_get_width ()

guint               clutter_actor_get_width             (ClutterActor *self);

Retrieves the width of a ClutterActor.

If the actor has a valid allocation, this function will return the width of the allocated area given to the actor.

If the actor does not have a valid allocation, this function will return the actor's natural width, that is the preferred width of the actor.

If you care whether you get the preferred width or the width that has been assigned to the actor, you should probably call a different function like clutter_actor_get_allocation_coords() to retrieve the allocated size or clutter_actor_get_preferred_width() to retrieve the preferred width.

If an actor has a fixed width, for instance a width that has been assigned using clutter_actor_set_width(), the width returned will be the same value.

If the actor has a valid allocation, this function will return the height of the allocated area given to the actor.

If the actor does not have a valid allocation, this function will return the actor's natural height, that is the preferred height of the actor.

If you care whether you get the preferred height or the height that has been assigned to the actor, you should probably call a different function like clutter_actor_get_allocation_coords() to retrieve the allocated size or clutter_actor_get_preferred_height() to retrieve the preferred height.

If an actor has a fixed height, for instance a height that has been assigned using clutter_actor_set_height(), the height returned will be the same value.

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.

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