                   const char *inline_style,
                   gboolean important);

Creates a new StThemeNode. Once created, a node is immutable. Of any of the attributes of the node (like the element_class ) change the node and its child nodes must be destroyed and recreated.

Parameters

context

the context representing global state for this themed tree

 

parent_node

the parent node of this node.

[allow-none]

theme

a theme (stylesheet set) that overrides the theme inherited from the parent node.

[allow-none]

element_type

the type of the GObject represented by this node in the tree (corresponding to an element if we were theming an XML document. G_TYPE_NONE means this style was created for the stage actor and matches a selector element name of 'stage'.

 

element_id

the ID to match CSS rules against.

[allow-none]

element_class

a whitespace-separated list of classes to match CSS rules against.

[allow-none]

pseudo_class

a whitespace-separated list of pseudo-classes (like 'hover' or 'visited') to match CSS rules against.

[allow-none]

Returns

the theme node.

[transfer full]


st_theme_node_get_parent ()

StThemeNode *
st_theme_node_get_parent (StThemeNode *node);

Gets the parent themed element node.

Parameters

node

a StThemeNode

st_theme_node_equal ()

gboolean
st_theme_node_equal (StThemeNode *node_a,
                     StThemeNode *node_b);

Compare two StThemeNodes. Two nodes which compare equal will match the same CSS rules and have the same style properties. However, two nodes that have ended up with identical style properties do not necessarily compare equal. In detail, node_a and node_b are considered equal iff

  • they share the same StTheme and StThemeContext

  • they have the same parent

  • they have the same element type

  • their id, class, pseudo-class and inline-style match

st_theme_node_lookup_color ()

gboolean
st_theme_node_lookup_color (StThemeNode *node,
                            const char *property_name,

                            ClutterColor *color);

Generically looks up a property containing a single color value. When specific getters (like st_theme_node_get_background_color()) exist, they should be used instead. They are cached, so more efficient, and have handling for shortcut properties and other details of CSS.

See also st_theme_node_get_color(), which provides a simpler API.

Parameters

node

a StThemeNode

 

property_name

The name of the color property

 

inherit

if TRUE, if a value is not found for the property on the node, then it will be looked up on the parent node, and then on the parent's parent, and so forth. Note that if the property has a value of 'inherit' it will be inherited even if FALSE is passed in for inherit ; this only affects the default behavior for inheritance.

 

color

location to store the color that was determined. If the property is not found, the value in this location will not be changed.

[out caller-allocates]

Returns

TRUE if the property was found in the properties for this theme node (or in the properties of parent nodes when inheriting.)

See also st_theme_node_get_double(), which provides a simpler API.

Parameters

node

a StThemeNode

 

property_name

The name of the numeric property

 

inherit

if TRUE, if a value is not found for the property on the node, then it will be looked up on the parent node, and then on the parent's parent, and so forth. Note that if the property has a value of 'inherit' it will be inherited even if FALSE is passed in for inherit ; this only affects the default behavior for inheritance.

 

value

location to store the value that was determined. If the property is not found, the value in this location will not be changed.

[out]

Returns

TRUE if the property was found in the properties for this theme node (or in the properties of parent nodes when inheriting.)


st_theme_node_lookup_length ()

                             gdouble *length);

Generically looks up a property containing a single length value. When specific getters (like st_theme_node_get_border_width()) exist, they should be used instead. They are cached, so more efficient, and have handling for shortcut properties and other details of CSS.

See also st_theme_node_get_length(), which provides a simpler API.

Parameters

node

a StThemeNode

 

property_name

The name of the length property

 

inherit

if TRUE, if a value is not found for the property on the node, then it will be looked up on the parent node, and then on the parent's parent, and so forth. Note that if the property has a value of 'inherit' it will be inherited even if FALSE is passed in for inherit ; this only affects the default behavior for inheritance.

 

length

location to store the length that was determined. If the property is not found, the value in this location will not be changed. The returned length is resolved to pixels.

[out]

Returns

TRUE if the property was found in the properties for this theme node (or in the properties of parent nodes when inheriting.)


st_theme_node_lookup_shadow ()

gboolean
st_theme_node_lookup_shadow (StThemeNode *node,
                             const char *property_name,

                             StShadow **shadow);

If the property is not found, the value in the shadow variable will not be changed.

Generically looks up a property containing a set of shadow values. When specific getters (like st_theme_node_get_box_shadow()) exist, they should be used instead. They are cached, so more efficient, and have handling for shortcut properties and other details of CSS.

See also st_theme_node_get_shadow(), which provides a simpler API.

Parameters

node

a StThemeNode

 

property_name

The name of the shadow property

 

inherit

if TRUE, if a value is not found for the property on the node, then it will be looked up on the parent node, and then on the parent's parent, and so forth. Note that if the property has a value of 'inherit' it will be inherited even if FALSE is passed in for inherit ; this only affects the default behavior for inheritance.

 

shadow

location to store the shadow.

[out]

Returns

TRUE if the property was found in the properties for this theme node (or in the properties of parent nodes when inheriting.), FALSE if the property was not found, or was explicitly set to 'none'.

void
st_theme_node_get_color (StThemeNode *node,
                         const char *property_name,
                         ClutterColor *color);

Generically looks up a property containing a single color value. When specific getters (like st_theme_node_get_background_color()) exist, they should be used instead. They are cached, so more efficient, and have handling for shortcut properties and other details of CSS.

If property_name is not found, a warning will be logged and a default color returned.

See also st_theme_node_lookup_color(), which provides more options, and lets you handle the case where the theme does not specify the indicated color.

Parameters

node

a StThemeNode

 

property_name

The name of the color property

 

color

location to store the color that was determined.

[out caller-allocates]

st_theme_node_get_double ()

                          const char *property_name);

Generically looks up a property containing a single numeric value without units.

See also st_theme_node_lookup_double(), which provides more options, and lets you handle the case where the theme does not specify the indicated value.

Parameters

node

gdouble
st_theme_node_get_length (StThemeNode *node,
                          const char *property_name);

Generically looks up a property containing a single length value. When specific getters (like st_theme_node_get_border_width()) exist, they should be used instead. They are cached, so more efficient, and have handling for shortcut properties and other details of CSS.

Unlike st_theme_node_get_color() and st_theme_node_get_double(), this does not print a warning if the property is not found; it just returns 0.

See also st_theme_node_lookup_length(), which provides more options.

Parameters

node

a StThemeNode

 

property_name

The name of the length property

 

Returns

the length, in pixels, or 0 if the property was not found.

StShadow *
st_theme_node_get_shadow (StThemeNode *node,
                          const char *property_name);

Generically looks up a property containing a set of shadow values. When specific getters (like st_theme_node_get_box_shadow()) exist, they should be used instead. They are cached, so more efficient, and have handling for shortcut properties and other details of CSS.

Like st_theme_get_length(), this does not print a warning if the property is not found; it just returns NULL

See also st_theme_node_lookup_shadow(), which provides more options.

Parameters

st_theme_node_get_content_box ()

void
st_theme_node_get_content_box (StThemeNode *node,
                               const ClutterActorBox *allocation,
                               ClutterActorBox *content_box);

Gets the box within an actor's allocation that contents the content of an actor (excluding borders and padding). This is a convenience function meant to be used from the allocate() or paint() methods of a ClutterActor subclass.

Parameters

node

a StThemeNode

 

allocation

the box allocated to a ClutterAlctor

 

content_box

computed box occupied by the actor's content.

[out caller-allocates]

st_theme_node_get_paint_box ()

void
st_theme_node_get_paint_box (StThemeNode *node,
                             const ClutterActorBox *allocation,
                             ClutterActorBox *paint_box);

Gets the box used to paint the actor, including the area occupied by properties which paint outside the actor's assigned allocation. When painting node to an offscreen buffer, this function can be used to determine the necessary size of the buffer.

Parameters

node

a StThemeNode

 

allocation

the box allocated to a ClutterActor

 

paint_box

computed box occupied when painting the actor.

[out caller-allocates]

st_theme_node_get_background_paint_box ()

void
st_theme_node_get_background_paint_box
                               (StThemeNode *node,
                                const ClutterActorBox *allocation,
                                ClutterActorBox *paint_box);

Gets the box used to paint the actor's background, including the area occupied by properties which paint outside the actor's assigned allocation.

Parameters

node

a StThemeNode

 

allocation

the box allocated to a ClutterActor

 

paint_box

computed box occupied when painting the actor's background.

[out caller-allocates]

st_theme_node_geometry_equal ()

gboolean
st_theme_node_geometry_equal (StThemeNode *node,
                              StThemeNode *other);

Tests if two theme nodes have the same borders and padding; this can be used to optimize having to relayout when the style applied to a Clutter actor changes colors without changing the geometry.

Parameters

node

a StThemeNode

 

other

a different StThemeNode

 

st_theme_node_paint_equal ()

gboolean
st_theme_node_paint_equal (StThemeNode *node,
                           StThemeNode *other);

Check if st_theme_node_paint() will paint identically for node as it does for other . Note that in some cases this function may return TRUE even if there is no visible difference in the painting.

Parameters

node

a StThemeNode

 

other

a different StThemeNode

 

Returns

TRUE if the two theme nodes paint identically. FALSE if the two nodes potentially paint differently.


st_theme_node_paint ()

void
st_theme_node_paint (StThemeNode *node,
                     CoglFramebuffer *framebuffer,
                     const ClutterActorBox *box,
                     guint8 paint_opacity);

[skip]


st_theme_node_copy_cached_paint_state ()

void
st_theme_node_copy_cached_paint_state (StThemeNode *node,
                                       StThemeNode *other);

Copy cached painting state from other to node . This function can be used to optimize redrawing cached background images when the style on an element changess in a way that doesn't affect background drawing. This function must only be called if st_theme_node_paint_equal (node, other) returns TRUE.

Parameters

node

a StThemeNode

 

other

a different StThemeNode
