import QtQuick 1.0
import "./styles/default" as DefaultStyles
import "./private" as Private // for ChoiceListPopup
// KNOWN ISSUES
// 1) Popout list does not have a scrollbar/scroll indicator or similar
// 2) The ChoiceListPopup should ff dynamically loaded, to support radically different implementations
// 3) Mouse wheel scroll events not handled by the popout ListView (see QTBUG-7369)
// 4) Support for configurable bindings between model's and ChoiceList's properties similar to ButtonBlock's is missing
