Function Documentation

QDeclarative_isFileCaseCorrect()

bool QDeclarative_isFileCaseCorrect

(

const QString &

fileName

)

Returns true if the case of fileName is equivalent to the file case of fileName on disk, and false otherwise.

This is used to ensure that the behavior of QML on a case-insensitive file system is the same as on a case-sensitive file system. This function performs a "best effort" attempt to determine the real case of the file. It may have false positives (say the case is correct when it isn't), but it should never have a false negative (say the case is incorrect when it is correct).

QDeclarative_setParent_noEvent()

void QDeclarative_setParent_noEvent ( QObject *  object, QObject *  parent  )

inline

Makes the object a child of parent.

Note that when using this method, neither parent nor the object's previous parent (if it had one) will receive ChildRemoved or ChildAdded events.
