Detailed Description

Creates a new DeclarativeMimeData by cloning the QMimeData passed as parameter. This is useful for two reasons :

• In DragArea, we want to clone our "working copy" of the DeclarativeMimeData instance, as Qt will automatically delete it after the drag and drop operation.
• In the drop events, the QMimeData is const, and we have troubles passing const to QML. So we clone it to remove the "constness"

This method will try to cast the QMimeData to DeclarativeMimeData, and will clone our extensions to QMimeData as well

source()

QQuickItem * DeclarativeMimeData::source

(

)

const

\qmlproperty item MimeData::source

Setting source to any existing qml item will enable the receiver of the drag and drop operation to know in which item the operation originated.

In the case of inter-application drag and drop operations, the source will not be available, and will be 0. Be sure to test it in your QML code, before using it, or it will generate errors in the console.

url()

QUrl DeclarativeMimeData::url

(

)

const

\qmlproperty url MimeData::url

Returns the first URL from the urls property of QMimeData TODO: We should use QDeclarativeListProperty<QUrls> to return the whole list instead of only the first element.
