57 * SECTION:ctknotebook
58 * @Short_description: A tabbed notebook container
59 * @Title: CtkNotebook
60 * @See_also: #CtkContainer
61 *
62 * The #CtkNotebook widget is a #CtkContainer whose children are pages that
63 * can be switched between using tab labels along one edge.
64 *
65 * There are many configuration options for CtkNotebook. Among other
66 * things, you can choose on which edge the tabs appear
67 * (see ctk_notebook_set_tab_pos()), whether, if there are too many
68 * tabs to fit the notebook should be made bigger or scrolling
69 * arrows added (see ctk_notebook_set_scrollable()), and whether there
70 * will be a popup menu allowing the users to switch pages.
71 * (see ctk_notebook_popup_enable(), ctk_notebook_popup_disable())
72 *
73 * # CtkNotebook as CtkBuildable
74 *
75 * The CtkNotebook implementation of the #CtkBuildable interface
76 * supports placing children into tabs by specifying “tab” as the
77 * “type” attribute of a <child> element. Note that the content
78 * of the tab must be created before the tab can be filled.
79 * A tab child can be specified without specifying a <child>
80 * type attribute.
81 *
82 * To add a child widget in the notebooks action area, specify
83 * "action-start" or “action-end” as the “type” attribute of the
84 * <child> element.
85 *
86 * An example of a UI definition fragment with CtkNotebook:
87 * |[
88 * <object class="CtkNotebook">
89 * <child>
90 * <object class="CtkLabel" id="notebook-content">
91 * <property name="label">Content</property>
92 * </object>
93 * </child>
94 * <child type="tab">
95 * <object class="CtkLabel" id="notebook-tab">
96 * <property name="label">Tab</property>
97 * </object>
98 * </child>
99 * </object>

123 *
124 * CtkNotebook has a main CSS node with name notebook, a subnode
125 * with name header and below that a subnode with name tabs which
126 * contains one subnode per tab with name tab.
127 *
128 * If action widgets are present, their CSS nodes are placed next
129 * to the tabs node. If the notebook is scrollable, CSS nodes with
130 * name arrow are placed as first and last child of the tabs node.
131 *
132 * The main node gets the .frame style class when the notebook
133 * has a border (see ctk_notebook_set_show_border()).
134 *
135 * The header node gets one of the style class .top, .bottom,
136 * .left or .right, depending on where the tabs are placed. For
137 * reorderable pages, the tab node gets the .reorderable-page class.
138 *
139 * A tab node gets the .dnd style class while it is moved with drag-and-drop.
140 *
141 * The nodes are always arranged from left-to-right, regarldess of text direction.
