Instead, grab it from hoveredRow, since almost always (with only one
exception) this is where the edit control has to be shown.
This makes it much easier to adjust views, e.g. add a new editable
field in the middle of configuration view, because it's not necessary
to manually change and test all the indexes below the row being
changed.
Additionally, it removes a lot of awkward and opaque row calculations.
This setting is generally useful, but it especially shines when
assembling, since the "same orientation" and "parallel" constraints
remove three and two rotational degrees of freedom, which makes them
impossible to use with 3d "point on line" constraint that removes
two spatial and two rotational degrees of freedom.
The setting is not enabled for all imported groups by default
because it exhibits some edge case failures. For example:
* draw two line segments sharing a point,
* constrain lengths of line segments,
* constrain line segments perpendicular,
* constrain line segments to a 90° angle.
This is a truly degenerate case and so it is not considered very
important. However, we can fix this later by using Eigen::SparseQR.
This removes the arbitrary 64 byte restriction (which effectively
limits us to as little as 16 Unicode characters with CJK encodings),
makes classes smaller, and is easier to use.
As a consequence of making the length of all ex-NameStr fields
unbounded, all functions that returned a buffer derived from those
were changed to return std::string. Then, functions that are
contextually similar to the ones described above were changed
to return std::string. Then, functions that now happened to mostly
take an std::string argument converted to a C string were changed
to accept std::string.
This has produced a bit of churn, but is probably for the better.
Now it is possible to give non-ASCII names to groups
as well as see non-ASCII filenames of imported files.
In the future this makes localization possible.
This works for LTR languages, such as European and CJK,
but not RTL such as Arabic. Does Arabic even exist in
monospaced form? I have no idea.
Almost all construction requests are lines, and allowing to
draw them as construction obviates the need to select them one
by one afterwards to convert them. Also, it removes the "not closed
contour" error message, which is a nice usability improvement.
This is equivalent to adding a constraint, then making it a reference.
The benefits are that:
* it's quicker;
* it avoids having an over-constrained system, with an associated
angry red flash and a regeneration delay.
The latter in particular is a very substantial usability improvement.
The reference distance command is useful most of the time,
but the reference angle one is also added for consistency.
Some extra code is necessary to determine that the back faces
should not be drawn in red for transparent solids. It is expected
that the user will first ensure that the shell is watertight
and then set the opacity; back faces are still drawn if
the opacity is exactly 1.
The savefile format is changed backwards-compatibly by stashing
the alpha value in uppermost byte of 4-byte hex color value
in Surface and Triangle clauses. The existing files have 00
in the high byte, so RgbColor::FromPackedInt treats that
as "opaque".
In principle, GTK3 is the way forward, and GTK2 is officially
deprecated, though still maintained. In practice however, GTK3
is often unbearably buggy; e.g. on my system, combo boxes
don't ever roll up in GTK3 windows. So I have added support
for both.
This required a few minor changes to the core, namely:
* GTK wants to know beforehand whether a menu item is a check
menu item or a regular one.
* GTK doesn't give us an easy way to execute something after
any event is processed, so an explicit idle timer is added.
This is a no-op on Win32.
* A few function signatures were const'ed, since GTK expects
immutable strings when converting to Glib::ustring.
The SolveSpace top-level directory was getting a bit cluttered, so
following the example of numerous other free-software projects, we move the
main application source into a subdirectory and adjust the build systems
accordingly.
Also, got rid of the obj/ directory in favor of creating it on the fly in
Makefile.msvc.
