They are here: [0]. There is a note at the end of the page which is quite important. The Gambas IDE is the single definitive reference if you really want to have an overview of all (or some) of the prefixes for graphical controls. I tend to forget these prefixes regularly and use slightly different ones (whatever sounds right). I guess nobody is expected to dive into the IDE to look up the correct prefix for a control :-) [0] http://gambaswiki.org/wiki/doc/naming -- "There's an old saying: Don't change anything... ever!" -- Mr. Monk ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
