C++ (Cpp) widgetIndexAt Examples

Example #1

void TabOrderEditor::contextMenuEvent(QContextMenuEvent *e)
{
    QMenu menu(this);
    const int target_index = widgetIndexAt(e->pos());
    QAction *setIndex = menu.addAction(tr("Start from Here"));
    setIndex->setEnabled(target_index >= 0);

    QAction *resetIndex = menu.addAction(tr("Restart"));
    menu.addSeparator();
    QAction *showDialog = menu.addAction(tr("Tab Order List..."));
    showDialog->setEnabled(m_tab_order_list.size() > 1);

    QAction *result = menu.exec(e->globalPos());
    if (result == resetIndex) {
        m_current_index = 0;
        m_beginning = true;
        update();
    } else if (result == setIndex) {
        m_beginning = false;
