    text
    copied!<p>Or, equivalently, how would you design such an API. Expected/example usage would be illustrative as well.</p> <p>My curiosity comes directly from the comments (and subsequent editting on my part) of this <a href="https://stackoverflow.com/questions/1105422/what-is-the-case-against-f/1105468#1105468">answer</a>. Similar <a href="https://stackoverflow.com/questions/58711/how-would-you-design-a-very-pythonic-ui-framework">questions/discussions</a> in the past provide a bit of inspiration to actually asking it.</p> <p>Executive summary:<br> <em>I don't feel a multithreaded UI api is possible in a meaningful way, nor particularly desirable. This view seems somewhat contentious and being a (relatively) humble man I'd like to see the error of my ways, if they actually are erroneous.</em></p> <p><sub>*Multithreaded is defined pretty loosely in this context, treat** it however makes sense to you.</sub></p> <hr> <p><s>Since this is pretty free-form, I'll be accepting whichever answer has the most coherent and well supported answer in my opinion; regardless of whether I agree with it.</s></p> <p><strong>Answer Accepted</strong></p> <hr> <p>**Ok, perhaps more clarification is necessary.</p> <p>Pretty much every serious application has more than one thread. At the very least, they'll spin up an additional thread to do some background task in <em>response</em> to a UI event.</p> <p><strong>I do not consider this a multithreaded UI.</strong></p> <p>All the UI work is being done on single thread still. I'd say, at a basic level, a multithreaded UI api would have to do away with (in some way) thread based ownership of UI objects or dispatching events to a single thread.</p> <p>Remeber, this is about the UI api itself; not the applications that makes use of it.</p>
