TabView.addOnClosePage

Emitted after [method@TabView.close_page] has been called for @page.

The handler is expected to call [method@TabView.close_page_finish] to confirm or reject the closing.

The default handler will immediately confirm closing for non-pinned pages, or reject it for pinned pages, equivalent to the following example:

static gboolean
close_page_cb (AdwTabView *view,
AdwTabPage *page,
gpointer    user_data)
{
adw_tab_view_close_page_finish (view, page, !adw_tab_page_get_pinned (page));

return GDK_EVENT_STOP;
}

The [method@TabView.close_page_finish] call doesn't have to happen inside the handler, so can be used to do asynchronous checks before confirming the closing.

A typical reason to connect to this signal is to show a confirmation dialog for closing a tab.
