## Detailed Description

Container which shows one of its children at a time, in tabbed windows.

The Gtk::Notebook widget is a Gtk::Container whose children are pages that can be switched between using tab labels along one edge.

A Notebook widget looks like this:

void Gtk::Notebook::remove_page | ( | Widget& | child ) |

void Gtk::Notebook::reorder_child | ( | Widget& | child,

| ) |  |

Sets widget as one of the action widgets.

Depending on the pack type the widget will be placed before or after the tabs. You can use a Gtk::Box if you need to pack more than one widget on the same side.

Note that action widgets are "internal" children of the notebook and thus not included in the list returned from Gtk::Container::foreach().

Since gtkmm 2.20:

Parameters:

  widget | A Gtk::Widget.
  pack_type | Pack type of the action widget.

void Gtk::Notebook::set_current_page | ( | int | page_num ) |

Switches to the page number page_num.

Note that due to historical reasons, GtkNotebook refuses to switch to a page unless the child widget is visible. Therefore, it is recommended to show child widgets before adding them to a notebook.

Parameters:

  page_num | Index of the page to switch to, starting from 0. If negative, the last page will be used. If greater than the number of pages in the notebook, nothing will be done.

void Gtk::Notebook::set_group_name | ( | const Glib::ustring & | group_name ) |

void Gtk::Notebook::set_menu_label | ( | Widget& | child,
|  | Widget& | menu_label
| ) |  |

Changes the menu label for the page containing child.

Parameters:

  child | The child widget.
  menu_label | The menu label, or `0` for default.

void Gtk::Notebook::set_menu_label_text | ( | Widget& | child,
|  | const Glib::ustring & | menu_text
| ) |  |

Creates a new label and sets it as the menu label of child.

Parameters:

  child | The child widget.
  menu_text | The label text.

void Gtk::Notebook::set_scrollable | ( | bool | scrollable = `true` ) |

Sets whether the tab label area will have arrows for scrolling if there are too many tabs to fit in the area.

Parameters:

  scrollable | `true` if scroll arrows should be added.

void Gtk::Notebook::set_show_border | ( | bool | show_border = `true` ) |

Sets whether a bevel will be drawn around the notebook pages.

This only has a visual effect when the tabs are not shown. See set_show_tabs().

Parameters:

  show_border | `true` if a bevel should be drawn around the notebook.

void Gtk::Notebook::set_show_tabs | ( | bool | show_tabs = `true` ) |

Sets whether to show the tabs for the notebook or not.

Parameters:

  show_tabs | `true` if the tabs should be shown.

void Gtk::Notebook::set_tab_detachable | ( | Widget& | child,
|  | bool | detachable = `true`
| ) |  |

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 gtk_notebook_set_group_id()) 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. |[ static void on_drop_zone_drag_data_received (GtkWidget *widget, GdkDragContext *context, `int` x, `int` y, GtkSelectionData *selection_data, `unsigned int` info, `unsigned int` time, gpointer user_data) { GtkWidget *notebook; GtkWidget **child;

notebook = gtk_drag_get_source_widget (context); child = (void*) selection_data->data;

process_widget (*child); gtk_container_remove (GTK_CONTAINER (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.

Since gtkmm 2.10:

Parameters:

  child | A child Gtk::Widget.
  detachable | Whether the tab is detachable or not.

void Gtk::Notebook::set_tab_label | ( | Widget& | child,
|  | Widget& | tab_label
| ) |  |

Changes the tab label for child.

If `0` is specified for tab_label, then the page will have the label 'page N'.

Parameters:

  child | The page.
  tab_label | The tab label widget to use, or `0` for default tab label.

void Gtk::Notebook::set_tab_label_text | ( | Widget& | child,
|  | const Glib::ustring & | tab_text
| ) |  |

Creates a new label and sets it as the tab label for the page containing child.

Parameters:

  child | The page.
  tab_text | The label text.

void Gtk::Notebook::set_tab_pos | ( | PositionType | pos ) |

Sets the edge at which the tabs for switching pages in the notebook are drawn.

Parameters:

  pos | The edge to draw the tabs at.

void Gtk::Notebook::set_tab_reorderable | ( | Widget& | child,
|  | bool | reorderable = `true`
