On this behalf, "Application.QueuAsyncCall" is more versatile.
But it's easy with TThread.Queue, as well.
- define a class (not to be derived from TThread) that holds the data
to be transferred and a procedure without parameters
- create an instance of that class
(where to store that instance?)
Nowhere, it is implicitly "stored" via the self-pointer of the argument
when calling TThread.Queue)
- use TThread.Queue to have the said procedure be executed by the main
thread
- at the end of the said procedure do "free" (without a prefix) this
will make the instance remoce itself.
You need a full queue for that, since the mainthread might not run till the
thread next queue()'s.
The fpc RTL does implement a full blown queue for managing TThread.Queue
and TThread.Synchronize.
