# enumeration QML Basic Type

a named enumeration value.

The `enumeration` type refers to a named enumeration value.

Each named value can be referred to as `<Type>.<value>`. For example, the Text type has an `AlignRight` enumeration value:

      Text { horizontalAlignment: Text.AlignRight }

(For backwards compatibility, the enumeration value may also be specified as a string, e.g. "AlignRight". This form is not recommended for new code.)

When integrating with C++, note that any `enum` value passed into QML from C++ is automatically converted into an `enumeration` value, and vice-versa.

This basic type is provided by the QML language. Some enumeration values are provided by the QtQuick import.

## Using the enumeration Type in QML

The `enumeration` type is a representation of a C++ `enum` type. It is not possible to refer to the `enumeration` type in QML itself; instead, the int or var types can be used when referring to `enumeration` values from QML code.

For example:

      import QtQuick 2.0

      Item {
          // refer to Text.AlignRight using an int type
          property int enumValue: textItem.horizontalAlignment

          signal valueEmitted(int someValue)

          Text {
              id: textItem
              horizontalAlignment: Text.AlignRight
          }

          // emit valueEmitted() signal, which expects an int, with Text.AlignRight
          Component.onCompleted: valueEmitted(Text.AlignRight)
      }
