# Detail

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 `Notebook`. Among other things, you can choose on which edge the tabs appear (see `notebookSetTabPos`), whether, if there are too many tabs to fit the noteobook 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 `notebookEnablePopup`)

- This function returned `()` in Gtk version 2.2.X and earlier

notebookRemovePage

Arguments

:: NotebookClass self |
=> self |
-> Int | `pageNum` - the index of a notebook page, starting from 0. If -1, the last page will be removed.
-> IO () |

Removes a page from the notebook given its index in the notebook.

Query the page the child widget is contained in.

- The function returns the page number if the child was found, Nothing otherwise.

notebookSetCurrentPage

Arguments

-> IO () |

Switches to the page number `pageNum`. Page numbers start from `0`. Use `-1` to request the last page.

- 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.

notebookNextPage :: NotebookClass self => self -> IO ()

Switches to the next page. Nothing happens if the current page is the last page.

notebookPrevPage :: NotebookClass self => self -> IO ()

Switches to the previous page. Nothing happens if the current page is the first page.

data Packing

Packing parameters of a widget

- The `Packing` parameter determines how the child behaves in the horizontal or vertical way in an `Graphics.UI.Gtk.Layout.HBox` or `Graphics.UI.Gtk.Layout.VBox`, respectively. `PackNatural` means the child is as big as it reqests. It will stay at the start of the end of a `Graphics.UI.Gtk.Layout.Box` if there is more space available. All children packed with `PackRepel` will be padded on both sides with additional space. `PackGrow` will increase the size of a widget so that it covers the available space. A menu bar, for instance, should always stay at the top of a window and should only occupy as little space as possible. Hence it should be packed at the start of a `Graphics.UI.Gtk.Layout.VBox` with the packing option `PackNatural`. The working area of a window (e.g. the text area in an editor) should expand when the window is resized. Here the packing option `PackGrow` is the right choice and it is irrelevant whether the main area is inserted at the start or the end of a box. Finally `PackRepel` is most useful in a window where no widget can make use of excess space. Examples include a dialog box without list boxes or text fields.

=> self |
-> child | `child` - the page
-> IO (Packing, PackType) |

Query the packing attributes for the tab label of the page containing `child`.

notebookSetTabLabelPacking

Arguments

notebookSetHomogeneousTabs

Arguments

:: NotebookClass self |
=> self |

-> IO () |

Sets whether the tabs must have all the same size or not.

- Warning: this function is deprecated and should not be used in newly-written code.

notebookSetTabLabel

Arguments

:: (NotebookClass self, WidgetClass child, WidgetClass tabLabel) |
=> self |
-> child | `child` - the page
-> tabLabel | `tabLabel` - the tab label widget to use
-> IO () |

Changes the tab label for `child`.

notebookSetTabLabelText

Arguments

:: (NotebookClass self, WidgetClass child) |
=> self |
-> child | `child` - the page
-> String | `tabText` - the label text
-> IO () |

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

notebookSetTabReorderable

Arguments

:: (NotebookClass self, WidgetClass child) |
=> self |
-> child | `child` - a child page
-> Bool | `reorderable` - whether the tab is reorderable or not.
-> IO () |

Sets whether the notebook tab can be reordered via drag and drop or not.

- Available since Gtk version 2.10

notebookGetTabReorderable

Arguments

:: (NotebookClass self, WidgetClass child) |
=> self |
-> child | `child` - the child page
-> IO Bool | return `True` if the tab is reorderable.

Gets whether the tab can be reordered via drag and drop or not.

- Available since Gtk version 2.10

notebookSetTabDetachable

Arguments

:: (NotebookClass self, WidgetClass child) |
=> self |
-> child | `child` - the child page
-> Bool | `detachable` - whether the tab is detachable or not
-> IO () |

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.

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

- Available since Gtk version 2.10

notebookGetTabDetachable

Arguments

:: (NotebookClass self, WidgetClass child) |
=> self |
-> child | `child` - the child page

-> widget |
-> PackType | `packType` pack type of the action widget
-> IO () |

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 `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 `containerForeach`.

- Available since Gtk version 2.20

notebookGetActionWidget

Arguments

:: NotebookClass self |
=> self |
-> PackType | `packType` pack type of the action widget to receive
-> IO (Maybe Widget) |

Gets one of the action widgets. See `notebookSetActionWidget`.

- Available since Gtk version 2.20
