gtk_assistant_update_buttons_state ()

void                gtk_assistant_update_buttons_state  (GtkAssistant *assistant);

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.

Since 2.10

The "complete" child property

  "complete"                 gboolean              : Read / Write

Setting the "complete" child property to TRUE marks a page as complete (i.e.: all the required fields are filled out). GTK+ uses this information to control the sensitivity of the navigation buttons.

Default value: FALSE

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
