Module dev

[David Rios]

Hi,

I'm trying to develop a module and I checked the example code on https://github.com/fcitx/fcitx5-quwei, and I'm wondering if it's possible to populate the candidate list asynchronously, like I make a request in an API for instance, and then after the response I populate the candidate list.

Could you please provide me with a few directions on that? Maybe the source code of a module that does something similar. That would be much appreciated.

All the best,

David

That would mainly depend on how you implement your asynchronous.

While the update to UI needs to happen in the main thread, you can
create the candidate list in another thread and set it to InputPanel
in the main thread.

If you use multi-threading, check EventDispatcher for a helper class
that sends a callback in the main thread. See
https://github.com/fcitx/fcitx5/blob/master/test/testeventdispatcher.cpp

If you have a file descriptor to monitor, you can check and use
addIOEvent https://codedocs.xyz/fcitx/fcitx5/classfcitx_1_1EventLoop.html
.

Thank you. If I create an event loop it just blocks the application, so I can't show a "loading" message and then update with the result. I would need to use the main application event loop, right? I tried using a dispatcher with Instance::eventLoop(), but nothing happens.

To better illustrate what I want using the quwei example:

When the code gets here: https://github.com/fcitx/fcitx5-quwei/blob/master/src/quwei.cpp#L275 , it means the user typed the correct combination, but then I want to show a candidate list that's only a "Loading" message. Meanwhile some processing is done in the background that will take a few seconds, and after finished it updates the candidate list with the computed options.

How do I go about that? Does that make sense?

Never mind, I managed to to what I wanted with ibus 😂.
