struct Adw::TabView::ClosePageSignal

Overview

Emitted after TabView#close_page has been called for @page.

The handler is expected to call 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:

WARNING ⚠️ The following code is in c ⚠️

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 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.
