Steve - obviously there are a few books and tutorials to skim through, but worth mentioning the meta-enter key (eg Cmd-enter on Mac) - this is spotter which is a universal grep and browser to help find things, as well as users of things (and lots more tricks)
Also, in the playground is where you can evaluate code like a repl- if you use meta-g on an expression you get a results inspector on the rhs which lets you explore and keep sliding over panes as you dive in (great for looking at results). You can also teach your own objects to add useful tabs to that browser to get a cheap ui (useful for starting out) Tim Sent from my iPhone > On 18 Dec 2019, at 08:47, Steve Davies <st...@connection-telecom.com> wrote: > > > > >> On Wed, 18 Dec 2019 at 10:42, Cédrick Béler <cdric...@gmail.com> wrote: >> >> >> > Le 18 déc. 2019 à 09:37, Sven Van Caekenberghe <s...@stfx.eu> a écrit : >> > >> > Here is the class comment of MQTTExperimentalClient, which would be the >> > one to use: >> > > > Thank you Sven and Cédrick for the pointers.
