Detailed Description

This header file contains a list of all error codes reported by Qt Quick Ultralite Core and Platform. It also contains a function to convert error code into string representation.

Note: Some of the error codes are only available in debug build. The error description mentions if it is available only in debug build. To enable all error checks, Qt Quick Ultralite Core and Platform needs to be rebuilt in debug build config.

See also Error handling.

Type Documentation

enum QulError

This enum type specifies the error codes that Qt Quick Ultralite Core and Platform reports. First error code in a range begins with range start + 1. Qt Quick Ultralite Core reserves error code range 1-99999, while Qt Quick Ultralite Platform reserves range 100001-199999. Values from 200001 onwards are reserved for custom errors.

The param1, param2, and param3 in Description are integer variables that are reported to the error handler.

Note: The following table of error codes is only for Qt Quick Ultralite developers' error analysis. They should not be used to control application logic.

Function Documentation

[since Qt Quick Ultralite 2.2] const char *errorCodeToString(QulError code)

Returns a pointer to C-string representation of the error code.

On debug build, the function returns a string representation for error range start values and error codes in the Core and Platform range. On release build, it returns a string representation for error range start values and empty string for the rest of error code values.

Note: Returns an empty string for error codes in the Custom range.

This function was introduced in Qt Quick Ultralite 2.2.
