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.
