enumeration QML Basic Type
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) }
