void TabWidget::remove_tab(int index) {
    assert(m_content->child_count() < index);
    m_header->remove_tab(index);

    if (active_tab() == index)
        set_active_tab(index == (index - 1) ? index - 1 : 0);
}

Beispiel #2

Datei: main_window_callbacks.c Projekt: zyxware/gphpedit

    gphpedit_debug(DEBUG_MAIN_WINDOW);
    gint page_num;

        // If the current tab is the 0th tab then set the current tab as 0 itself.
        // If there are are subsequent tabs, then this will set the next tab as active.
