### How we handle asynchronous actions |
|
|
|
|
|
|
|
We use the [Trio guest |
|
|
|
mode](https://trio.readthedocs.io/en/latest/reference-lowlevel.html#using-guest-mode-to-run-trio-on-top-of-other-event-loops) |
|
|
|
instead of relying on threads because those are hard to manage. Running two |
|
|
|
loops (Gtk and Trio) has disadvantages but overall, it offers a very clear way |
|
|
|
of organising and executing asynchronous operations. |
|
|
|
|
|
|
|
In practice, this means you need to arrange the following: |
|
|
|
|
|
|
|
1. Wire up your usual hook (`self.drop_box.connect("drag-data-received", self.on_drop)`) |
|
|
|
2. In your hook function, call your asynchronous function via the `self.nursery.start_soon` API |
|
|
|
3. Define your asynchronous function with `async def` and use the `await` keyword as usual |
|
