31 * CSS nodes are the backbone of the CtkStyleContext implementation and
32 * replace the role that CtkWidgetPath played in the past. A CSS node has
33 * an element name and a state, and can have an id and style classes, which
34 * is what is needed to determine the matching CSS selectors. CSS nodes have
35 * a 'visible' property, which makes it possible to temporarily 'hide' them
36 * from CSS matching - e.g. an invisible node will not affect :nth-child
37 * matching and so forth.
38 *
39 * The API to manage states, names, ids and classes of CSS nodes is:
40 * - ctk_css_node_get/set_state. States are represented as CtkStateFlags
41 * - ctk_css_node_get/set_name. Names are represented as interned strings
42 * - ctk_css_node_get/set_id. Ids are represented as interned strings
43 * - ctk_css_node_add/remove/has_class and ctk_css_node_list_classes. Style
44 * classes are represented as quarks.
45 *
46 * CSS nodes are organized in a dom-like tree, and there is API to navigate
47 * and manipulate this tree:
48 * - ctk_css_node_set_parent
49 * - ctk_css_node_insert_before/after
50 * - ctk_css_node_get_parent
51 * - ctk_css_node_get_first/last_child
52 * - ctk_css_node_get_previous/next_sibling
53 * Note that parents keep a reference on their children in this tree.
54 *
55 * Every widget has one or more CSS nodes - the first one gets created
56 * automatically by CtkStyleContext. To set the name of the main node,
57 * call ctk_widget_class_set_css_name() in class_init(). Widget implementations
58 * can and should add subnodes as suitable.
59 *
60 * Best practice is:
61 * - For permanent subnodes, create them in init(), and keep a pointer
62 * to the node (you don't have to keep a reference, cleanup will be
63 * automatic by means of the parent node getting cleaned up by the
64 * style context).
65 * - For transient nodes, create/destroy them when the conditions that
66 * warrant their existence change.
67 * - Keep the state of all your nodes up-to-date. This probably requires
68 * a ::state-flags-changed (and possibly ::direction-changed) handler,
69 * as well as code to update the state in other places. Note that CTK+
70 * does this automatically for the widget's main CSS node.
71 * - The sibling ordering in the CSS node tree is supposed to correspond
72 * to the visible order of content: top-to-bottom and left-to-right.
73 * Reorder your nodes to maintain this correlation. In particular for
74 * horizontally layed out widgets, this will require listening to
75 * ::direction-changed.
76 * - The draw function should just use ctk_style_context_save_to_node() to
77 * 'switch' to the right node, not make any other changes to the style
78 * context.
79 *
80 * A noteworthy difference between ctk_style_context_save() and
81 * ctk_style_context_save_to_node() is that the former inherits all the
82 * style classes from the main CSS node, which often leads to unintended
83 * inheritance.

86/* When these change we do a full restyling. Otherwise we try to figure out
87 * if we need to change things. */
