SS rotates the model when middle button dragging while some users expect
this operation to rotate the camera where left-right and up-down directions are
reversed instead. This adds that option.
Make the `TriStateButton` class "universal" and use it in place of the
`OccludedLinesButton` class which is now removed.
Fix the tool-tips on the constraint button to show what will come instead
of what is - just like the the occluded lines button. Also change the
text of the tool-tips wording to be more clear and consistent with other
buttons.
Small stylistic and code formatting changes.
Fixes#920#1143
Explanation from @robnee on Feb 7, 2021 in pull request #927
Solvespace uses two timers (generateAllTimer and showTWTimer) to defer tasks
until the event loop processing finishes. This helps coalesce multiple calls
into one. You can call scheduleGenerateAll multiple times while processing UI
messages but only trigger one GenerateAll. scheduleGenerateAll and
scheduleShowTW do their scheuduling by setting timers with durations of zero.
These timers fire (at least on Linux and Windows) some time after all other
events in the message queue have been processed. This works fine when
scheduling either one of these tasks. However, there is no guarantee in what
order the timers will fire (at least on Windows) regardless of which order the
scheduling calls are made. It's pretty easy to demonstrate (on some platforms)
by adding logging to the scheduling calls and timer callbacks.
In many cases TextWindow::Show depends on generateAll happening first. This
causes UI glitches where displays don't update and their contents are stale.
Since this behavior is not deterministic it's easy to imagine how this problem
could make certain bug reports difficult to reproduce and diagnose. #920 is a
good example. It also makes syncing up UI behavior across all platforms a
challenge.
Solving this in the platform domain is tricky. This is PR endeavors to make the
ordering of deferred calls to TextWindow::Show and generateAll deterministic.
It does this by replacing generateAllTimer and showTWTimer with a single
refreshTimer. Calls to scheduleGenerateAll and scheduleShowTW set flags to note
the requested operations and schedule the refreshTimer. A new callback function
SolveSpaceUI::Refresh can then check the flags and ensure that generateAll
happens first. It fixes#920. Moreover, this PR makes it easy to observe and
reproduce this problem reliably and across all platforms by simply reordering
the calls in the Refresh callback.
It's pretty clear that the ordering is important so some solution is needed, if
for no other reason than the sanity of the devs. I think this is a pretty good
solution as it spells out the ordering. If nothing else this PR is helpful in
further investigations.
@ruevs @phkahler I'd like to hear your thoughts.
Where each entity in the active workplane sketch is projected a
different amount normal to the workplane, to allow inspection and
easier selection of entities that entirely overlap each other and are
thus otherwise difficult to see or select.
The distance between the exploded "layers" can be controlled in the
configuration page. Negative distances mean the layers are projected in
the opposite direction, relative to the workplane normal.

* Don't use a reserved identifier in include guards.
* Use fabs() from <cmath> instead of our own ffabs().
This shouldn't make any difference with modern toolchains.
* Convert a few preprocessor macros to constexprs.

Allows distancing users from the internal "elem" member.
Add Get() and operator[].
Replace direct references to elem.
Make elem and elemsAllocated private in IdList/List.
Supported metric units: km, m, cm, mm, µm, nm.
Supported USCS units: in, mil, µin.
Also, use the newly introduced unit formatting machinery in tools for
measuring perimeter, area and volume, so that e.g. volume is not
displayed in millions of cubic millimeters.
This is useful in niche cases, like making angular measurement tools.
Also, use simpler and more principled code for numeric precision
while editing constraints: don't special-case angles, but use up to
10 digits after the decimal point for everything.
Also, mark not just curves, but also points and normals derived from
construction requests as construction.
Also, don't always mark arc center point as construction just to
exclude it from chord tolerance bounding box calculation; instead,
special-case it there.
This serves two purposes.
First, we want to (some day) convert these messages into a less
obtrustive form, something like toaster notifications, such that they
don't interrupt workflow as harshly. That would, of course, be
nonblocking.
Second, some platforms, like Emscripten, do not support nested event
loops, and it's not possible to display a modal dialog on them
synchronously.
When making this commit, I've reviewed all Error() and Message()
calls to ensure that only some of the following is true for all
of them:
* The call is followed a break or return statement that exits
an UI entry point (e.g. an MenuX function);
* The call is followed by cleanup (in fact, in this case the new
behavior is better, since even with a synchronous modal dialog
we have to be reentrant);
* The message is an informational message only and nothing
unexpected will happen if the operation proceeds in background.
In general, all Error() calls already satisfied the above conditions,
although in some cases I changed control flow aroudn them to more
clearly show that. The Message() calls that didn't satisfy these
conditions were reworked into an asynchronous form.
There are three explicit RunModal() calls left that need to be
reworked into an async form.
This commit removes Platform::Window::Redraw function, and rewrites
its uses to run on timer events. Most UI toolkits have obscure issues
with recursive event handling loops, and Emscripten is purely event-
driven and cannot handle imperative redraws at all.
As a part of this change, the Platform::Timer::WindUp function
is split into three to make the interpretation of its argument
less magical. The new functions are RunAfter (a regular timeout,
setTimeout in browser terms), RunAfterNextFrame (an animation
request, requestAnimationFrame in browser terms), and
RunAfterProcessingEvents (a request to run something after all
events for the current frame are processed, used for coalescing
expensive operations in face of input event queues).
This commit changes two uses of Redraw(): the AnimateOnto() and
ScreenStepDimGo() functions. The latter was actually broken in that
on small sketches, it would run very quickly and not animate
the dimension change at all; this has been fixed.
While we're at it, get rid of unused Platform::Window::NativePtr
function as well.
This is to address MSVC warnings.
This commit changes a few configuration fields to use double instead
of float. There doesn't seem to be any reason these use float except
for the legacy Windows code using float for saved configuration.
Changing their type to double improves consistency.
