As an aside what annoys me about image lists in Delphi is that they lump all images in one big dfm blob. I like to keep my icons in icon files and link them as a resource. Then load them up at runtime. It means that when you need to update one you just change the ico file in one place. But then you don't get to see icons at design time. I'd like to have my icons in resources and see them at design time. Such a system must be possible.

Multithreading in Python is inevitably blocked by the GIL. Nothing you can do about it. No magic solution. See countless discussions of this topic on the broader internet. In other words the issue is not related to Delphi or p4d but is a fundamental design choice in Python.

This question is the one that drives statisticians around the world completely mad. You need to decide on your goals before deciding what data to collect.

Why return a pointer to self? You just risk having that pointer outlive the record instance. Make this a constructor or a static class function that returns a new instance. BTW I remembered wrongly before. No need for a helper to implement a static class function that returns rTxt.

The final function can't be right. It should be a static class function, but that's not enough. What would it return? A pointer to what instance? You'd need to allocate an instance somewhere. I'd use a helper record to get around the inability to forward declare value types.

When polling you need a methodology. If you poll the entire population, it's easy. But if you poll just a sample, then you need to choose the sample carefully so that it is representative, and you need to follow up non respondents. There is a lot of science in polling to get meaningful data. A self selecting poll on a site like this will not tell you very much if anything about the overall population. But perhaps you just want to know what active members of this site use. And even if that's what you want, it will be hard to impossible to get accurate data

Quite odd to copy some code from an SO question that is in the wrong language. This code is Java.

Which means the original idea was doomed.

You could make a minimal example. The issue is surely with your program.

Make that minimal reproduction already

A minimal reproduction. The act of making one will likely show you what you did wrong.

Show us a minimal reproduction of the issue. Then we can talk.

This is known to be unreliable

Of course it makes sense. Try declaring set of TObject and see how that works out. You'd need to constrain to an ordinal type with 256 or fewer elements and you can't do that with constraints. Too bad we can't have templates.

Whilst you can't use constraints, you can use generics and RTTI to get some effective code reuse when working with enums and sets. Ideally this could be done truly generically but such is life with Delphi.

We can't see what the class does. You've just shown the interface.

I think the answer is still no.

I cannot understand what you mean by event in component or instance. In fact I can't make any sense out of this.

I can't understand the question at all

If you want to fully test your own app this is the way to go, so that you get top down allocation for all the addresses in your program. You won't necessarily find all the issues if you only do the fastmm local allocator. Using OS top down has always worked well for me.
