Notebook

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> ]|

CSS nodes

|[ notebook ├── header.top │ ├── [<action widget>] │ ├── tabs │ │ ├── arrow │ │ ├── tab │ │ │ ╰── <tab label> ┊ ┊ ┊ │ │ ├── tab[.reorderable-page] │ │ │ ╰── <tab label> │ │ ╰── arrow │ ╰── [<action widget>] │ ╰── stack ├── <child> ┊ ╰── <child> ]|

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, regarldess of text direction.

From Container

gtkContainer GtkContainer* gtkContainer;: the main Gtk struct
getContainerStruct GtkContainer* getContainerStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
removeAll void removeAll(): Removes all widgets from the container
getType GType getType()
add void add(Widget widget): Adds @widget to @container. Typically used for simple containers such as #GtkWindow, #GtkFrame, or #GtkButton; for more complicated layout containers such as #GtkBox or #GtkGrid, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_grid_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can’t place the same widget inside two different containers.
checkResize void checkResize()
childGetProperty void childGetProperty(Widget child, string propertyName, Value value): Gets the value of a child property for @child and @container.
childGetValist void childGetValist(Widget child, string firstPropertyName, void* varArgs): Gets the values of one or more child properties for @child and @container.
childNotify void childNotify(Widget child, string childProperty): Emits a #GtkWidget::child-notify signal for the [child property][child-properties] @child_property on the child.
childNotifyByPspec void childNotifyByPspec(Widget child, ParamSpec pspec): Emits a #GtkWidget::child-notify signal for the [child property][child-properties] specified by @pspec on the child.
childSetProperty void childSetProperty(Widget child, string propertyName, Value value): Sets a child property for @child and @container.
childSetValist void childSetValist(Widget child, string firstPropertyName, void* varArgs): Sets one or more child properties for @child and @container.
childType GType childType(): Returns the type of the children supported by the container.
forall void forall(GtkCallback callback, void* callbackData): Invokes @callback on each direct child of @container, including children that are considered “internal” (implementation details of the container). “Internal” children generally weren’t added by the user of the container, but were added by the container implementation itself.
foreac void foreac(GtkCallback callback, void* callbackData): Invokes @callback on each non-internal child of @container. See gtk_container_forall() for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls.
getBorderWidth uint getBorderWidth(): Retrieves the border width of the container. See gtk_container_set_border_width().
getChildren ListG getChildren(): Returns the container’s non-internal children. See gtk_container_forall() for details on what constitutes an "internal" child.
getFocusChain bool getFocusChain(ListG focusableWidgets): Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores %NULL in @focusable_widgets and returns %FALSE.
getFocusChild Widget getFocusChild(): Returns the current focus child widget inside @container. This is not the currently focused widget. That can be obtained by calling gtk_window_get_focus().
getFocusHadjustment Adjustment getFocusHadjustment(): Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().
getFocusVadjustment Adjustment getFocusVadjustment(): Retrieves the vertical focus adjustment for the container. See gtk_container_set_focus_vadjustment().
getPathForChild WidgetPath getPathForChild(Widget child): Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including @child.
getResizeMode GtkResizeMode getResizeMode(): Returns the resize mode for the container. See gtk_container_set_resize_mode ().
propagateDraw void propagateDraw(Widget child, Context cr): When a container receives a call to the draw function, it must send synthetic #GtkWidget::draw calls to all children that don’t have their own #GdkWindows. This function provides a convenient way of doing this. A container, when it receives a call to its #GtkWidget::draw function, calls gtk_container_propagate_draw() once for each child, passing in the @cr the container received.
remove void remove(Widget widget): Removes @widget from @container. @widget must be inside @container. Note that @container will own a reference to @widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use @widget again, you need to add a reference to it before removing it from a container, using g_object_ref(). If you don’t want to use @widget again it’s usually more efficient to simply destroy it directly using gtk_widget_destroy() since this will remove it from the container and help break any circular reference count cycles.
resizeChildren void resizeChildren()
setBorderWidth void setBorderWidth(uint borderWidth): Sets the border width of the container.
setFocusChain void setFocusChain(ListG focusableWidgets): Sets a focus chain, overriding the one computed automatically by GTK+.
setFocusChild void setFocusChild(Widget child): Sets, or unsets if @child is %NULL, the focused child of @container.
setFocusHadjustment void setFocusHadjustment(Adjustment adjustment): Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See gtk_scrolled_window_get_hadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_vadjustment() for setting the vertical adjustment.
setFocusVadjustment void setFocusVadjustment(Adjustment adjustment): Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the vertical alignment. See gtk_scrolled_window_get_vadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_hadjustment() for setting the horizontal adjustment.
setReallocateRedraws void setReallocateRedraws(bool needsRedraws): Sets the @reallocate_redraws flag of the container to the given value.
setResizeMode void setResizeMode(GtkResizeMode resizeMode): Sets the resize mode for the container.
unsetFocusChain void unsetFocusChain(): Removes a focus chain explicitly set with gtk_container_set_focus_chain().
