|
||
* @Short_description: A tabbed notebook container
|
||
* @Title: GtkNotebook
|
||
* @See_also: #GtkContainer
|
||
*
|
||
* The #GtkNotebook widget is a #GtkContainer whose children are pages that
|
||
* can be switched between using tab labels along one edge.
|
||
*
|
||
* There are many configuration options for GtkNotebook. Among other
|
||
* things, you can choose on which edge the tabs appear
|
||
* (see gtk_notebook_set_tab_pos()), whether, if there are too many
|
||
* tabs to fit the notebook should be made bigger or scrolling
|
||
* arrows added (see gtk_notebook_set_scrollable()), and whether there
|
||
* will be a popup menu allowing the users to switch pages.
|
||
* (see gtk_notebook_popup_enable(), gtk_notebook_popup_disable())
|
||
*
|
||
* # GtkNotebook as GtkBuildable
|
||
*
|
||
* The GtkNotebook implementation of the #GtkBuildable interface
|
||
* supports placing children into tabs by specifying “tab” as the
|
||
* “type” attribute of a <child> element. Note that the content
|
||
* of the tab must be created before the tab can be filled.
|
||
* A tab child can be specified without specifying a <child>
|
||
* type attribute.
|
||
*
|
||
* To add a child widget in the notebooks action area, specify
|
||
* "action-start" or “action-end” as the “type” attribute of the
|
||
* <child> element.
|
||
*
|
||
* An example of a UI definition fragment with GtkNotebook:
|
||
* |[
|
||
* <object class="GtkNotebook">
|
||
* <child>
|
||
* <object class="GtkLabel" id="notebook-content">
|
||
* <property name="label">Content</property>
|
||
* </object>
|
||
* </child>
|
||
* <child type="tab">
|
||
* <object class="GtkLabel" id="notebook-tab">
|
||
* <property name="label">Tab</property>
|
||
* </object>
|
||
* </child>
|
||
* </object>
|
||
* ]|

|
||
*
|
||
* GtkNotebook has a main CSS node with name notebook, a subnode
|
||
* with name header and below that a subnode with name tabs which
|
||
* contains one subnode per tab with name tab.
|
||
*
|
||
* If action widgets are present, their CSS nodes are placed next
|
||
* to the tabs node. If the notebook is scrollable, CSS nodes with
|
||
* name arrow are placed as first and last child of the tabs node.
|
||
*
|
||
* The main node gets the .frame style class when the notebook
|
||
* has a border (see gtk_notebook_set_show_border()).
|
||
*
|
||
* The header node gets one of the style class .top, .bottom,
|
||
* .left or .right, depending on where the tabs are placed. For
|
||
* reorderable pages, the tab node gets the .reorderable-page class.
|
||
*
|
||
* A tab node gets the .dnd style class while it is moved with drag-and-drop.
|
||
*
|
||
* The nodes are always arranged from left-to-right, regardless of text direction.
