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.
