Method
ClutterActorallocate_available_size
Declaration [src]
void
clutter_actor_allocate_available_size (
ClutterActor* self,
gfloat x,
gfloat y,
gfloat available_width,
gfloat available_height
)
Description [src]
Allocates self taking into account the ClutterActor‘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 if (request_mode == CLUTTER_REQUEST_WIDTH_FOR_HEIGHT)
{
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);
}
else if (request_mode == CLUTTER_REQUEST_CONTENT_SIZE)
{
clutter_content_get_preferred_size (content, &natural_width, &natural_height);
width = CLAMP (natural_width, 0, available_width);
height = CLAMP (natural_height, 0, available_height);
}
box.x1 = x; box.y1 = y;
box.x2 = box.x1 + available_width;
box.y2 = box.y1 + available_height;
clutter_actor_allocate (self, &box);
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.
