FLTK's Fl_Input widget, instantiated as {Graphics,Text}EditControl, returns
a 'const char *' string. In order to handle this properly, several of
SolveSpace's internal routines needed to gain a "const" qualifier on the
edit-control string argument.
String literals in C++ are implicitly typed as 'const char *', and with
this change, their const-ness is maintained when assigning them to
variables or passing them as arguments. This significantly cuts down the
number of warnings generated by the compiler.
and up for special things, the number of times that a group may
be stepped is limited to 999. So avoid a crash by not letting
the user specify more than that.

color picker.
And apply same rule to rewrite nearly-white colors (when exporting
with a file format typically viewed on a white background) for fill
color as for stroke color.
[git-p4: depot-paths = "//depot/solvespace/": change = 2176]
in the text window. This means that I can move the conversion from
half-row and column to (x, y) into the platform-independent code,
and that I'll be ready to add my color picker.
[git-p4: depot-paths = "//depot/solvespace/": change = 2171]
circles, using a numerical method. And the user can specify a
radius, instead of letting us choose automatically, and specify
whether the original lines should be kept and made construction, or
deleted.
[git-p4: depot-paths = "//depot/solvespace/": change = 2146]
useful because it makes it possible to add cosmetic dimensions to
an existing model, without REF appended.
[git-p4: depot-paths = "//depot/solvespace/": change = 2140]
possible. This replaces all of the color-coded links, that I liked
but that were nonstandard.
Also rip out the old sweep and helical sweep UI; that was disabled,
but the code was still present.
And fix dependencies in makefile, since textwin.cpp depends on the
icons now.
[git-p4: depot-paths = "//depot/solvespace/": change = 2139]
to draw those, and hit test with the mouse, and display tool tips
when the user hovers with the mouse. Also, underline links only
when they're hovered, and not otherwise.
And add a separate menu option to align the view to the active
workplane, vs. activating the active group's workplane, and
remap the bottom two graphics window toolbar icons to that and
"nearest iso view" instead of draw in 2d/3d, since people tended
to click on those without understanding and cause trouble.
And by default, we force a parallel projection; so the factory
default camera tangent is now 0.3, not 0.
[git-p4: depot-paths = "//depot/solvespace/": change = 2131]
easy and useful. Also make the volume measurement use Message(),
and not a separate text window screen.
And make Edit -> Unselect All (Esc) clear the marks drawn to
indicate free parameters, since it clears all the other temporary
stuff drawn in the graphics window.
[git-p4: depot-paths = "//depot/solvespace/": change = 2121]
rotation. Also clean up the handling of units, by putting the
conversion factors in only one place, and clean up the
expression-parsing but removing all the copies of the same error
message.
[git-p4: depot-paths = "//depot/solvespace/": change = 2093]
does that, and adds a scale factor to that transformation (instead
of just mirroring, as before), but also:
* Replace the "import mirrored" mechanism with a scale factor,
which if negative corresponds to a reflection as well.
* Fix self-intersection checker to report a meaningful point
when edges are collinear.
* Don't blow an assertion on some types of invalid file;
instead provide a nice error message to the user.
* Clear the naked edges before each regen.
* Don't create zero-length line segments by snapping a line
segment's end to its beginning.
[git-p4: depot-paths = "//depot/solvespace/": change = 2086]
one point to be dragged simultaneously. So now a dragged point
drags all the selected points and entities, and a dragged entity
drags its points (except for circles, which drag the radius).
This means that the number of forced points for the solver must now
be unlimited, and it is.
Also add commands to invert the selection within the active group,
and to select an edge chain starting from the current selection.
And redo the context menus a bit; still not great, but less
cluttered and more systematic.
[git-p4: depot-paths = "//depot/solvespace/": change = 2064]
and parametric entities. Also consolidate the text screen functions
to change group options into a single function for everything.
[git-p4: depot-paths = "//depot/solvespace/": change = 2051]
point-coincident constraints and the entity- or group-generated
constraints. Also fix a bug where a dragged point was not released
when the mouse pointer left the window.
[git-p4: depot-paths = "//depot/solvespace/": change = 2045]
instead of tying that to whether the shaded model is shown. And
rewrite all URLs to solvespace.com, not www.solvespace.com, and get
rid of the nag screen that I just added because opening the website
with ShellExecute seems to freeze a bit on startup.
[git-p4: depot-paths = "//depot/solvespace/": change = 2044]
perspective and parallel projections. Add a snap grid, for points
and for text comments. Draw text comments in the plane of their
workplane if they have one, otherwise always facing forward.
And fix a few nasty bugs: the possibility of an extremely long
animation onto a workplane, accidental use of the wrong style line
width for constraints, misplaced text box in style screen for
default styles, other little stuff.
[git-p4: depot-paths = "//depot/solvespace/": change = 2037]
formats, with the proper color and width. This may need a bit of
cleanup for stuff like the hidden line removal, which currently
loses the style.
Also fix a bug in the test for arcs of a circle. A second-order
Bezier with collinear control points really is an arc, but it's an
arc with infinite radius so stuff tends to blow up. So return false
for that one.
[git-p4: depot-paths = "//depot/solvespace/": change = 2030]
line width units, on-screen and export visibility. So now we can
use that to modify the default styles, or to create custom styles.
Also add code to draw fat lines, with round endcaps, since gl
doesn't do that.
Next we need some user interface to assign styles to entities, and
to make all the export file formats support the style attributes.
[git-p4: depot-paths = "//depot/solvespace/": change = 2029]
mechanism. This gets filled in from some defaults, and stored in
the registry. The default styles do not get saved in the file, but
user-created styles (which aren't supported yet) do.
[git-p4: depot-paths = "//depot/solvespace/": change = 2028]
size for EPS, etc.). This can either be fixed, with a given width
and height and offset, or automatic, by the left right bottom top
margins.
And draw nicer dimensions for length, with arrows and more
extension lines. Add code to trim those lines against the
(rectangular, axis-aligned) box that contains the actual number,
and use that (instead of the elliptical interpolation, which was
only approximately right) for diameter dimensions too.
[git-p4: depot-paths = "//depot/solvespace/": change = 2027]
window screen, and remind the user that they could 'fix' the
problem by working with meshes instead.
[git-p4: depot-paths = "//depot/solvespace/": change = 1962]
according to the user's preference. I templated the housekeeping
stuff for Boolean operations and step and repeat, so it's
relatively clean.
Still need to add the stuff to make a mesh vertex-to-vertex, and to
export sections of a mesh.
[git-p4: depot-paths = "//depot/solvespace/": change = 1959]
exact surface shells. And add interference checking; I'll be lazy
and just do that on the meshes, by modifying the self-intersection
tester to ignore coplanar triangles (since that can happen in an
assembly).
[git-p4: depot-paths = "//depot/solvespace/": change = 1958]

it's the shell's triangulation.
[git-p4: depot-paths = "//depot/solvespace/": change = 1957]

things, but this is more or less as it should be.
[git-p4: depot-paths = "//depot/solvespace/": change = 1944]

simplify use of the constraint solver in a library.
[git-p4: depot-paths = "//depot/solvespace/": change = 1942]
our specified section plane; we then split them according to the
start and endpoints of each STrimBy, using de Castejau's algorithm.
These sections get projected (possibly in perspective, which I do
correctly) into 2d and exported.
Except, for now they just get pwl'd in the export files. That's the
fallback, since it works for any file format. But that's the place
to add special cases for circles etc., or to export them exactly.
DXF supports the latter, but very painfully since I would need to
write a later-versioned file, which requires thousands of lines of
baggage. I'll probably stick with arcs.
[git-p4: depot-paths = "//depot/solvespace/": change = 1936]
and curve.cpp and surface.cpp contain the rest.
Also get rid of the meshError stuff; will just use the nakedEdges
mechanism for that. And I won't run the interference test
continuously, have added a menu item for that.
[git-p4: depot-paths = "//depot/solvespace/": change = 1934]
triangle join. And add controls to show and hide the solid model
edges (independently of the shaded mesh), and to suppress the
shaded triangles from SVG/EPS output.
[git-p4: depot-paths = "//depot/solvespace/": change = 1932]
trimmed line), and plane-line intersection. Terminate the Bezier
surface subdivision on a chord tolerance, and that seems okay now.
And print info about the graphics adapter in the text window, could
be useful.
Also have a cylinder-detection routine that works; should special
case those surfaces in closed form since they are common, but not
doing it yet.
[git-p4: depot-paths = "//depot/solvespace/": change = 1928]

numbers, for that new dimension value.

unsatisfied constraints when we don't converge.
[git-p4: depot-paths = "//depot/solvespace/": change = 1874]
just applies an offset to the DXF before exporting. Useful enough
to be worth the ugliness, though.
This is the stupid routines from SketchFlat, slightly reworked.
[git-p4: depot-paths = "//depot/solvespace/": change = 1866]
but the mesh doesn't get combined. That effectively hides it, good
for looking inside and such.
[git-p4: depot-paths = "//depot/solvespace/": change = 1860]
linear segments to generate, irrespective of the chord tolerance.
That used to be hard-coded, and it needs to be small enough to
avoid lags while working interactively, but I also need to export
fine geometry.
[git-p4: depot-paths = "//depot/solvespace/": change = 1857]
some magic numbers. This would be trivial to break, but still more
difficult than patching the binary to skip the check...
