### Interfaces

GtkAssistant implements AtkImplementorIface and `GtkBuildable`.

### Detailed Description

A `GtkAssistant` is a widget used to represent a generally complex operation splitted in several steps, guiding the user through its pages and controlling the page flow to collect the necessary data.

### GtkAssistant as GtkBuildable

The GtkAssistant implementation of the GtkBuildable interface exposes the `action.area` as internal children with the name "action_area".

To add pages to an assistant in GtkBuilder, simply add it as a <child> to the GtkAssistant object, and set its child properties as necessary.

### Structures

`GtkAssistant`

  undocumented

### Convenient Construction

`gtkAssistant` is the equivalent of `gtkAssistantNew`.

### Enums and Flags

`GtkAssistantPageType`

  An enum for determining the page role inside the `GtkAssistant`. It's used to handle buttons sensitivity and visibility.

  Note that an assistant needs to end its page flow with a page of type GTK_ASSISTANT_PAGE_CONFIRM or GTK_ASSISTANT_PAGE_SUMMARY to be correct.

  `content`

    The page has regular contents.

  `intro`

    The page contains an introduction to the assistant task.

  `confirm`

    The page lets the user confirm or deny the changes.

  `summary`

    The page informs the user of the changes done.

  `progress`

    Used for tasks that take a long time to complete, blocks the assistant until the page is marked as complete.

### User Functions

`GtkAssistantPageFunc(current.page, data)`

  A function used by `gtkAssistantSetForwardPageFunc` to know which is the next page given a current one. It's called both for computing the next page when the user presses the "forward" button and for handling the behavior of the "last" button.

  `current.page`

    The page number used to calculate the next page.

  `data`

    user data.

  Returns: [integer] The next page number.

### Signals

`apply(assistant, user.data)`

  The ::apply signal is emitted when the apply button is clicked. The default behavior of the `GtkAssistant` is to switch to the page after the current page, unless the current page is the last one.

  A handler for the ::apply signal should carry out the actions for which the wizard has collected data. If the action takes a long time to complete, you might consider to put a page of type `GTK_ASSISTANT_PAGE_PROGRESS` after the confirmation page and handle this operation within the `"prepare"` signal of the progress page. Since 2.10

  `assistant`

    the `GtkAssistant`

  `user.data`

    user data set when the signal handler was connected.

`cancel(assistant, user.data)`

  The ::cancel signal is emitted when then the cancel button is clicked. Since 2.10

  `assistant`

    the `GtkAssistant`

  `user.data`

    user data set when the signal handler was connected.

`close(assistant, user.data)`

  The ::close signal is emitted either when the close button of a summary page is clicked, or when the apply button in the last page in the flow (of type `GTK_ASSISTANT_PAGE_CONFIRM`) is clicked. Since 2.10

  `assistant`

    the `GtkAssistant`

  `user.data`

    user data set when the signal handler was connected.

`prepare(assistant, page, user.data)`

  The ::prepare signal is emitted when a new page is set as the assistant's current page, before making the new page visible. A handler for this signal can do any preparation which are necessary before showing `page`. Since 2.10

  `assistant`

    the `GtkAssistant`

  `page`

    the current page

  `user.data`

    user data set when the signal handler was connected.

### Style Properties

`content-padding` [integer : Read]

  Number of pixels around the content pages. Allowed values: >= 0 Default value: 1

`header-padding` [integer : Read]

  Number of pixels around the header. Allowed values: >= 0 Default value: 6
