## Description

The `gtk.Notebook` widget is a `gtk.Container` whose children are overlapping pages that can be switched between by using tab labels along one edge. There are many configuration options for the `gtk.Notebook`. You can choose on which edge the tabs appear (see `set_tab_pos`()); whether the notebook should be made bigger or scrolling arrows added if there are too many tabs to fit (see `set_scrollable`()); and, whether there will be a popup menu allowing the users to switch pages. (see `popup_enable`(), `popup_disable`()).

The `gtk.Notebook` is particularly useful for displaying a large number of application controls that can be grouped into several functional areas. The typical example is the user preferences dialog in some applications. For example, a notebook page can be setup for each of font selection, color selection, formating, etc.

## Constructor

        gtk.Notebook()

Returns : | the newly created `gtk.Notebook`

If `fill` is `True` the label widget in the tab can use up all the space in the tab. The `pack_type` can be one of `gtk.PACK_START` or `gtk.PACK_END` to specify whether the tab is packed to the left or right if tabs are on the top or bottom edge (top or bottom if the tabs are on the left or right edge).See `gtk.Box.pack_start`() for the exact meaning of the parameters.

### gtk.Notebook.reorder_child

        def reorder_child(child, position)

`child` : | the child widget to move
`position` : | the index of the page that `child` is to move to, or -1 to move to the end

        def set_tab_reorderable(child, reorderable)

`child` : | a child `gtk.Widget`
`reorderable` : | if `True` the tab is reorderable.

### Note

This method is available in PyGTK 2.10 and above.

The `set_tab_reorderable`() method sets the "reorderable" property of `child` to the value of `reorderable`. If `reorderable` is `True`, the notebook tab can be reordered via drag and drop.

### gtk.Notebook.get_tab_detachable

        def get_tab_detachable(child)

`child` : | a child `gtk.Widget`
Returns : | if `True` the tab is detachable.

### Note

This method is available in PyGTK 2.10 and above.

The `get_tab_detachable`() method returns the value of the "detachable" property of `child`. The method returns `True` if the tab contents can be detached from `notebook`.

### gtk.Notebook.set_tab_detachable

        def set_tab_detachable(child, detachable)

`child` : | a child `gtk.Widget`
`detachable` : | if `True` the tab is detachable or not

### Note

This method is available in PyGTK 2.10 and above.

The `set_tab_detachable`() method sets the "detachable" property of `child` to the value specified by `detachable`. If `detachable` is `True`, `child` can be moved from this notebook to another notebook or widget.

Note that two notebooks must share a common group identifier (see the `set_group_id`() method) 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 reference 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.

## Signals

### The "change-current-page" gtk.Notebook Signal

        def callback(notebook, offset, user_param1, ...)

`notebook` : | the notebook that received the signal
`offset` : | the count of pages to move (negative count is backward)
`user_param1` : | the first user parameter (if any) specified with the `connect`() method
`...` : | additional user parameters (if any)

The "change-current-page" signal is emitted when the page forward or page backward request is issued.

### The "focus-tab" gtk.Notebook Signal

        def callback(notebook, type, user_param1, ...)

`notebook` : | the notebook that received the signal
`type` : | the type of tab: `gtk.NOTEBOOK_TAB_FIRST` or `gtk.NOTEBOOK_TAB_LAST`
`user_param1` : | the first user parameter (if any) specified with the `connect`() method
`...` : | additional user parameters (if any)
Returns : | `True` if the signal was handled

The "focus-tab" signal is emitted when the focus is changed by tabbing.

### The "move-focus-out" gtk.Notebook Signal

        def callback(notebook, direction_type, user_param1, ...)

`notebook` : | the notebook that received the signal
`direction_type` : | the direction type of the focus move: `gtk.DIR_TAB_FORWARD`, `gtk.DIR_TAB_BACKWARD`, `gtk.DIR_UP`, `gtk.DIR_DOWN`, `gtk.DIR_LEFT` or `gtk.DIR_RIGHT`
`user_param1` : | the first user parameter (if any) specified with the `connect`() method
`...` : | additional user parameters (if any)

The "move-focus-out" signal is emitted when the focus is moved out of the notebook with the specified `direction_type`.

### The "page-added" Signal

        def callback(notebook, child, page_num, user_param1, ...)

`notebook` : | the notebook that received the signal
`child` : | the child `gtk.Widget` affected
`page_num` : | the new page number for `child`
`user_param1` : | the first user parameter (if any) specified with the `connect`() method
`...` : | additional user parameters (if any)

### Note

This signal is available in PyGTK 2.10 and above.

The "page-added" signal is emitted when a page is added to the notebook.

### The "page-removed" Signal

        def callback(notebook, child, page_num, user_param1, ...)

`notebook` : | the notebook that received the signal
`child` : | the child `gtk.Widget` affected
`page_num` : | the new page number for `child`
`user_param1` : | the first user parameter (if any) specified with the `connect`() method
`...` : | additional user parameters (if any)

### Note

This signal is available in PyGTK 2.10 and above.

The "page-removed" signal is emitted after a page is removed from the notebook.

### The "page-reordered" Signal

        def callback(notebook, child, page_num, user_param1, ...)

`notebook` : | the notebook that received the signal
`child` : | the child `gtk.Widget` affected
`page_num` : | the new page number for `child`
`user_param1` : | the first user parameter (if any) specified with the `connect`() method
`...` : | additional user parameters (if any)

### Note

This signal is available in PyGTK 2.10 and above.

The "page-reordered" signal is emitted when a page has been reordered.

### The "select-page" gtk.Notebook Signal

        def callback(notebook, move_focus, user_param1, ...)

`notebook` : | the notebook that received the signal
`move_focus` : | if `True` move the focus to a child widget
`user_param1` : | the first user parameter (if any) specified with the `connect`() method
`...` : | additional user parameters (if any)
Returns : | `True` if the signal was handled

The "select-page" signal is emitted when a new child page is selected.

### The "switch-page" gtk.Notebook Signal

        def callback(notebook, page, page_num, user_param1, ...)

`notebook` : | the notebook that received the signal
`page` : | the new current page
`page_num` : | the index of the new current page
`user_param1` : | the first user parameter (if any) specified with the `connect`() method
`...` : | additional user parameters (if any)

The "switch-page" signal is emitted when the notebook page is changed. Note the `page` parameter is a GPointer and not usable within PyGTK. Use the `page_num` parameter to retrieve the new current page using the `get_nth_page`() method.
