我開始爲我的閃亮新BB10開發Alpha B與Cascades(懷疑我可以在WebWorks上實現功能齊全的Mp3播放器,即使我真的很喜歡),我已經開發一直在努力使QML,並在https://developer.blackberry.com/cascades/documentation/dev/integrating_cpp_qml/index.html描述c + +發揮很好,但無論在哪裏,我把產權別名的位置無效
property alias artistText: artist.Text
的QNX Momentics的IDE抱怨它正對無效的位置。我還沒有找到任何指導應該在哪裏說屬性,所以我決定在這裏問。
import bb.cascades 1.0

您應該添加一些上下文,即周圍的代碼。 –
正如我所說,放置它並不重要,它會拋出一個錯誤,但我會把代碼放在上面。 – Machinarius
