示例1: widgetAt

// First, resolve symbol since there are ambiguities. Take the first one which is the
// overload for (int,int) and call by address instead off name to overcome that.
const QtInfo &qtInfo = QtInfo::get(ctx);
const std::string func =
qtInfo.prependQtModule("QApplication::widgetAt",
qtInfo.version >= 5 ? QtInfo::Widgets : QtInfo::Gui);
const SymbolList symbols = SymbolGroupValue::resolveSymbol(func.c_str(), ctx, errorMessage);
if (symbols.empty())
return std::string(); // Not a gui application, likely
