.. currentmodule:: PySide6.QtQml
.. py:decorator:: QmlAttached
This decorator declares that the enclosing type attaches the type passed as
an attached property to other types. This takes effect if the type is exposed
to QML using a ``QmlElement()`` or ``@QmlNamedElement()`` decorator.
.. code-block:: python
QML_IMPORT_NAME = "com.library.name"
QML_IMPORT_MAJOR_VERSION = 1
QML_IMPORT_MINOR_VERSION = 0 # Optional
@QmlAnonymous
class LayoutAttached(QObject):
@Property(QMargins)
def margins(self):
...
@QmlElement()
@QmlAttached(LayoutAttached)
class Layout(QObject):
...
Afterwards the class may be used in QML:
.. code-block:: javascript
import com.library.name 1.0
Layout {
Widget {
Layout.margins: [2, 2, 2, 2]
}
}
