The CairoStatus class

Introdução

CairoStatus is used to indicate errors that can occur when using Cairo. In some cases it is returned directly by functions. but when using CairoContext, the last error, if any, is stored in the object and can be retrieved with CairoContext::status or cairo_status(). New entries may be added in future versions.

Use Cairo::statusToString or cairo_status_to_string() to get a human-readable representation of an error message.
