QPropertyBindingError is used by \l{The Property System}{the property system} to report errors that occurred when a binding was evaluated. Use \l type() to query which error occurred, and \l description() to extract an error message which might contain more details. If there is no error, QPropertyBindingError has type QPropertyBindingError::NoError
and hasError()
returns false.
Definition at line 140 of file qproperty.h.
This enum specifies which error occurred.
\value NoError No error occurred while evaluating the binding. \value BindingLoop Binding evaluation was stopped because a property depended on its own value. \value EvaluationError Binding evaluation was stopped for any other reason than a binding loop. For example, this value is used in the QML engine when an exception occurs while a binding is evaluated. \value UnknownError A generic error type used when neither of the other values is suitable. Calling \l description() might provide details.

QPropertyBindingError::QPropertyBindingError | ( | ) |
Default constructs QPropertyBindingError. hasError() will return false, type will return NoError
and \l description() will return an empty string.
Definition at line 818 of file qproperty.cpp.
Constructs a QPropertyBindingError of type type with description as its description.

QPropertyBindingError::QPropertyBindingError | ( | const QPropertyBindingError & | other | ) |
Copy-constructs QPropertyBindingError from other.
Definition at line 838 of file qproperty.cpp.
QPropertyBindingError::QPropertyBindingError | ( | QPropertyBindingError && | other | ) |
Move-constructs QPropertyBindingError from other. other will be left in its default state.
Definition at line 856 of file qproperty.cpp.
QPropertyBindingError::~QPropertyBindingError | ( | ) |
Destroys the QPropertyBindingError.
Definition at line 874 of file qproperty.cpp.
QString QPropertyBindingError::description | ( | ) | const |
