These aren't entries in the changelog since they're bug fixes for new
code since the last release -- the entries on the changelog are
unaffected.
- focused and occluded no longer is explicitly set to false. Now, once
the window has been fully initialized, the values are read from winit
which will cause callbacks to be fired if the value has changed.
- The automatic_layout parameter if outer_position had its meaning
inverted. Passing true now properly ensures the window is
automatically positioned.
- synchronize_platform_window is now called prior to the first redraw.
This allows the `visible` attribute to be changed from false to true.
- Some window attributes are automatically set based on the incoming
dynamic.
- Some initial window values are delayed until after the first layout to
minimze "noisy" values.
All of these changes now allow a window that is resize_to_fit to be
initially hidden and show itself centered after being initially resized
without any flashing or on-screen movement/resizing.
map_each previously was written such that if a chain of mappings fed
each other, a deadlock could occur because while the first one was
mapped, the second callback gets invoked and tries to update the first
value while it's still being held.
This refactor switches from std Mutex to parking_lot, allowing me to
remove a workaround for needing to run drop callbacks in a separate
thread during the drop of a DynamicGuard.
In addition to that change, the lower level `map_generational` calls now
take a DynamicGuard as their parameter. This allows these functions to
drop ownership of the referenced data during the callback.
The map_each implementation takes advantage of this by ensuring that the
guard is dropped before set is invoked, minimizing potential lock overlaps.
With this refactor, some old code of mine with complex validations now works
again.
This commit adds my first take at creating a harness for a user's guide
using the new capture functionality. The example has tests that ensure
the align widget creates the expected results.
Somehow I missed that my changes for weak callbacks broke the theme
editor. I thought I had it working with the try_get changes, but I
discovered several flaws in this approach.
In the end, ownership has been transferred to the CallbackHandle, and a
CallbackHandle can relinquish its reference to create weak graphs. This
is how weak_clone now works.
This ensures frames render consistently.
This change only affects the animation recorder. The regular virtual
recorder interface blocks when refresh is called.
