Hi,

How to get the current TThread instance?

For example: I created a TThread and called a function, which calls a function .... One of those sub functions needs to call TThread.Synchronize, which needs as parameter the current TThread.

There is no documented method.

Pass on the TThread instance.

You could use GetCurrentThreadID and a lookup list.

Strange.
Am I really the first needing this?

You mean as parameter?
Some functions are predefined events. That means I call them and they call me back. I would like to avoid adding everywhere another parameter.

What about using a

threadvar CurrentThread: Thread;

?
TThread could set this in the constructor.

BTW, you can call Synchronize for another thread than the current. Is that allowed?

Apparently.
I never needed such a method, and I use threads extensively :-)

Yes.

I understand that. Well, you could create an event object for the event handler.

This could be done, but will give errors for externally created threads.

But you can easily do this for your own thread objects.

It's a method like any other. Why not ?

Michael.

And for threads created with BeginThread.

But you can easily do this for your own thread objects.

I also think that's the best solution. If that's not enough, then doing it in tthread won't be enough either (unless you only support applications that exclusively use tthread-based threads).

We currently use this method for our "in Application" scheduler, but IIRC you have to fetch/set the ID in the Execute method. But having the overhead of using threadvars (mentionent on the list some time ago) I am currently looking for another method too.
