## Detailed Description

A widget used to guide users through multi-step operations.

A Gtk::Assistant is a widget used to represent a generally complex operation split into several steps, guiding the user through its pages and controlling the page flow to collect the necessary data.

Gtk::Assistant maintains a Gtk::AssistantPage object for each added child, which holds additional per-child properties. You obtain the Gtk::AssistantPage for a child with get_page().

## ◆ signal_apply()

Glib::SignalProxy<void()> Gtk::Assistant::signal_apply | ( |  | ) |

Slot Prototype:
  `void on_my_apply()`

Flags: Run Last

Emitted when the apply button is clicked.

The default behavior of the `Gtk::Assistant` is to switch to the page after the current page, unless the current page is the last one.

A handler for the signal_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 putting a page of type Gtk::AssistantPage::Type::PROGRESS after the confirmation page and handle this operation within the signal_prepare() signal of the progress page.

Deprecated: 4.10: This widget will be removed in GTK 5

## ◆ signal_cancel()

Glib::SignalProxy<void()> Gtk::Assistant::signal_cancel | ( |  | ) |

Flags: Run Last

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::AssistantPage::Type::CONFIRM) is clicked.

Deprecated: 4.10: This widget will be removed in GTK 5

## ◆ signal_prepare()

Glib::SignalProxy<void(Gtk::Widget*)> Gtk::Assistant::signal_prepare | ( |  | ) |

Slot Prototype:
  `void on_my_prepare(Gtk::Widget* page)`

Flags: Run Last

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 preparations which are necessary before showing page.

Deprecated: 4.10: This widget will be removed in GTK 5

Parameters

  page | The current page.

## ◆ update_buttons_state()

void Gtk::Assistant::update_buttons_state | ( |  | ) |

Forces assistant to recompute the buttons state.

GTK automatically takes care of this in most situations, e.g. when the user goes to a different page, or when the visibility or completeness of a page changes.

One situation where it can be necessary to call this function is when changing a value on the current page affects the future page flow of the assistant.

Deprecated: 4.10: This widget will be removed in GTK 5
