How do I share data between C++ gauges in a shared cockpit scenario?

Question:

Can we send any data over this system so not only built in FS enums and structs ? Same goes for the events, can we send custom events also ?

I'm thinking of making one big struct that contains all the custom data that is used in my gauges (that's over a 100 variables) and then creating events for all of these. Would that work ?

Yes, Björn, you can send any data over this system that you want. In the example above, a gauge-specific CLOCK_EVENT is sent in one case; a CLOCK_DATA struct is sent in another case. So yes, you can create a big struct (presumably for serialization and deserialization) and events for all of the different state changes that can occur in your gauges. Just make sure that you aren't sending a big struct every time an event is sent over or performance could suffer.

Thx for the reply Susan, one more question if I may... You are using the new FS10 gauge header to do the serialization, deserialzation etc... but this requires a gauge (or a number of gauges, but I prefer 1 gauge) to do the sending/receiving. this also requires that the gauge has to be loaded at one point. To avoid this I have been using a timer based system. In short, I'm moving all of the intelligence that's now incorporated inside the gauges, out of the actual gauge and into a number of functions that are fired based on a windows timer. The big advantage being that all the calculations are in one place, and that I don't need to worry about people using FS in 2D vs 3D mode (VC). So, is there any possibility to move the ser/deser/event code out of a gauge and into the timer based system ? (I start and stop the timer in the module_init and module_deinit events)

Thx again for the help !
