AddOn functions call back

poco2013 — Tue, 04 Oct 2022 14:39:11 GMT

I believe it is possible to call one plugin from another. Is it possible to call a function within one plugin from another plugin ?

if so, any documentation?

I am asking out of convenience. If one compiles and loads the Example plugins. One could easily create a new addon which could directly call those pre-defined functions without having to cut/paste the function and all its resources?

There is a example in the Communications Manager that calls the Do place Text function in the Communication client addon.

But it uses a command identifier of 'CmID to identify the text command.
Where is this identifier assigned? Is it something you have to program or is it pre-assigned.
Say I wanted to call a function from the Element_Test Add-On? How would I assign a identifier to a particular function in that add on so that I could call it from ACAPI_Command_Call()??

Yes, it's possible. You can find detailed documentation for this topic here: http://archicadapi.graphisoft.com/documentation/communication-manager

Let's call the plugin which has the function as "Server Add-On" and the plugin which calls that function as "Client Add-On".
The "Client Add-On" can call only those functions from "Server Add-On" which have been registered with ACAPI_Register_SupportedService function in the RegisterInterface function of the "Server Add-On". That function tells ARCHICAD that the Add-On can be called by another and it gives an identifier for the registered function. So the "Client Add-On" will be able to use that identifier (+ the MDID of the "Server Add-On") to call it.
Feel free to choose any identifier. The type of the identifier is GSType (=UInt32).

Thanks for the documentation Reference.

That explains the required hook-up fairly well. I tried it out and it seems to work OK.

Thanks
