While this was a workaround for a docs.rs issue (Px/Lp are not
linked), I decided having the shorter import path would look better in
the examples.
It probably wasn't necessary to update all of the references in the
internal code, but I decided it was worth the consistency.
Closes#91
There's some details to still figure out, which are in new issues:
- #109: When opening a window, no handle is returned that gives access to the
window from the opener. Technically this can all be wired up manually,
with exception of requeesting the window close.
- #107: How can a window close itself? Once we have a handle type, we still
need a mechanism to allow a button on a window request that the window
closes gracefully. The examples that currently close the window
call exit instad.
Installing a callback now returns a CallbackHandle. All map-style APIs
install this handle automatically on the created dynamic, which keeps
the callback installed until the dynamic is freed. All other APIs
return the handle for the caller to either call persist() or store
somewhere.
Now, the dynamic system can be used for application-long data with
almost no fear of leaking data due to how callbacks are being installed.
Technically cycles are still possible by moving clones into the
callbacks, so a WeakDynamic type might be worth exposing.
