// This routine is very specific to this toolkit
// It's annoying and has to be copied to each widget when there are changes
// it could be 'simplfied' maybe or made to be more generic, but this is as far as I've gotten
// it's probably not worth working much more on this toolkit, the andlabs/ui has been great and got me here!
// but it's time to write direct GTK, QT, macos and windows toolkit plugins
