GI.Gtk.Objects.Notebook

The Notebook widget is a Container 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 notebookSetTabPos), whether, if there are too many tabs to fit the notebook should be made bigger or scrolling arrows added (see notebookSetScrollable), and whether there will be a popup menu allowing the users to switch pages. (see notebookPopupEnable, notebookPopupDisable)

GtkNotebook as GtkBuildable

The GtkNotebook implementation of the Buildable 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: > >class="GtkNotebook" > child > class="GtkLabel" id="notebook-content" > name="label"Content/property > /object > /child > type="tab" > class="GtkLabel" id="notebook-tab" > 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 notebookSetShowBorder).

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.

setTabDetachable

notebookSetTabDetachable

Arguments

:: (HasCallStack, MonadIO m, IsNotebook a, IsWidget b)

=> a

notebook: a Notebook

-> b

child: a child Widget

-> Bool

detachable: whether the tab is detachable or not

-> m ()

Sets whether the tab can be detached from notebook to another notebook or widget.

Note that 2 notebooks must share a common group identificator (see notebookSetGroupName) to allow automatic tabs interchange between them.

If you want a widget to interact with a notebook through DnD (i.e.: accept dragged tabs from it) it must be set as a drop destination and accept the target “GTK_NOTEBOOK_TAB”. The notebook will fill the selection with a GtkWidget** pointing to the child widget that corresponds to the dropped tab.

Note that you should use notebookDetachTab instead of containerRemove if you want to remove the tab from the source notebook as part of accepting a drop. Otherwise, the source notebook will think that the dragged tab was removed from underneath the ongoing drag operation, and will initiate a drag cancel animation.

C code

static void
on_drag_data_received (GtkWidget        *widget,
                       GdkDragContext   *context,
                       gint              x,
                       gint              y,
                       GtkSelectionData *data,
                       guint             info,
                       guint             time,
                       gpointer          user_data)
{
  GtkWidget *notebook;
  GtkWidget **child;

  notebook = gtk_drag_get_source_widget (context);
  child = (void*) gtk_selection_data_get_data (data);

  // process_widget (*child);

  gtk_notebook_detach_tab (GTK_NOTEBOOK (notebook), *child);
}

If you want a notebook to accept drags from other widgets, you will have to set your own DnD code to do it.
