Detailed Description
QPropertyBindingError is used by the property system to report errors that occurred when a binding was evaluated. Use type() to query which error occurred, and 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.
Member Type Documentation
enum QPropertyBindingError::Type
This enum specifies which error occurred.
| Constant | Value | Description |
|---|---|---|
| QPropertyBindingError::NoError | 0 | No error occurred while evaluating the binding. |
| QPropertyBindingError::BindingLoop | 1 | Binding evaluation was stopped because a property depended on its own value. |
| QPropertyBindingError::EvaluationError | 2 | 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. |
| QPropertyBindingError::UnknownError | 3 | A generic error type used when neither of the other values is suitable. Calling description() might provide details. |
