This function previously returned an int32_t. Presuming that it measures
the length of time since the application was started, the 32-bit type would
cause the returned value to wrap from 2^31-1 to -2^31 after a little less
than twenty-five days.
* Added "Show Menu Bar" and "Full Screen" menu items, which will be
implemented in the FLTK interface. These are currently prevented from
appearing in the Win32 interface by the HAVE_FLTK and
HAVE_FLTK_FULLSCREEN macros.
* Moved the "Show Text Window" down below the "Show Toolbar" item, so that
"Show Menu Bar", "Show Toolbar" and "Show Text Window" are in the same
vertical order as their corresponding UI elements typically take on
* Added new platform-dependent routines to back the new menu items:
void ToggleMenuBar(void);
bool MenuBarIsVisible(void);
void ToggleFullScreen(void);
bool FullScreenIsActive(void);
These are stubs in the Win32 code.
* Fleshed out the system header #includes in solvespace.h, and moved them
to the top of the file per convention
* Rewrote the file dialog selection patterns in terms of macros that allow
them to expand to either the FLTK or Windows formats
* Don't use __stdcall in SSGL_CALLBACK, and make SSGL_CALLBACK 'extern "C"'
as OpenGL usually expects function pointers to point to C functions
GCC and Clang's -Wfloat-equal warning notes that comparing floating-point
values with == or != may be questionable. But the few instances of these in
SolveSpace are defensibly correct (as discussed with Jonathan), so to keep
folks from getting nervous that a CAD application isn't handling its floats
correctly, we define an EXACT() macro inside which the -Wfloat-equal
warning is disabled. This macro will also serve as a source-code
annotation, like a comment but better.
(The warning is only disabled for Clang, alas, because GCC is particular
about where _Pragma() can be used. This isn't so bad, however, because the
warning is much easier to enable on Clang [thanks to -Weverything], whereas
with GCC it has to be requested explicitly.)
This commit consists of numerous small changes, none significant enough to
merit a commit on their own:
* Added extra braces to quash for-loop variable scoping issues for older
compilers (or "g++ -fno-for-scope")
* Appeased "unreachable code" warnings, spurious or otherwise
* Added casts to fix integer-variable signedness warnings
* Added a dummy virtual method to the VectorFileWriter class to silence the
-Wweak-vtables warning from Clang++
* Renamed some parameters in the Expr and GraphicsWindow classes to
eliminate "parameter shadows a field" warnings
* Removed an inert "0 ||" from a conditional, and changed a "&& 0" into an
"#if 0"
* Added missing elements to array/struct/class initializers to zap further
warnings
* Indented some cpp conditionals where appropriate
* Qualified some variables and functions as static to quiet "no previous
declaration" warnings
* toolbar.cpp needed to #include<icons-proto.h> to fix those same "no
previous declaration" warnings from icons.h
* Added some casts and const qualifiers to the Win32 code to address
warnings produced by g++ when compiling under MinGW
* Rewrote Cnf{Freeze,Thaw}Float() to use a union rather than pointer
aliasing; this makes g++ a lot happier
* Removed redundant #includes from win32/w32util.cpp
* With Jonathan's blessing, shortened the last line of the About dialog
text to better match the preceding lines
This change comprehensively replaces the use of Microsoft-standard integer
and boolean types with their C99/C++ standard equivalents, as the latter is
more appropriate for a cross-platform application. With matter-of-course
exceptions in the Win32-specific code, the types/values have been converted
as follows:
QWORD --> uint64_t
SQWORD --> int64_t
DWORD --> uint32_t
SDWORD --> int32_t
WORD --> uint16_t
SWORD --> int16_t
BYTE --> uint8_t
BOOL --> bool
TRUE --> true
FALSE --> false
The following related changes are also included:
* Added C99 integer type definitions for Windows, as stdint.h is not
available prior to Visual Studio 2010
* Changed types of some variables in the SolveSpace class from 'int' to
'bool', as they actually represent boolean settings
* Implemented new Cnf{Freeze,Thaw}Bool() functions to support boolean
variables in the Registry
* Cnf{Freeze,Thaw}DWORD() are now Cnf{Freeze,Thaw}Int()
* TtfFont::Get{WORD,DWORD}() are now TtfFont::Get{USHORT,ULONG}() (names
inspired by the OpenType spec)
* RGB colors are packed into an integer of type uint32_t (nee DWORD), but
in a few places, these were represented by an int; these have been
corrected to uint32_t
GraphicsWindow::menu[] previously recorded both item names (e.g. "Open...")
and accelerator labels ("Ctrl+O") in .label, and accelerator key/mask
values in .accel. Not only were the accelerator labels redundant given the
latter, they are not needed by GUI toolkits like FLTK, which generate them
from key/mask values.
So we remove the accelerator portion from each menu-item label, and define
a new MakeAcceleratorLabel() routine which takes a key/mask value and
returns the appropriate label. We make use of this new routine in
CreateGraphicsWindowMenus() and GraphicsWindow::ToolbarDrawOrHitTest().
* Added a comment header identifying the columns
* Added Ctrl-Q accelerator for "Exit", as this is standard
* Replaced a Latin-1 "degree" character with an octal escape, to avoid
source-file encoding issues
* Undefine (some of) the convenience macros used to define the table
(the method aliases are numerous and unlikely to collide with anything)
If we are to synthesize accelerator labels from values of
GraphicsWindow::menu[].accel, it will be more straightforward if
accelerators are represented in the same way that they appear in the menu.
(Windows does return the keystroke as VK_OEM_PERIOD with a Shift modifier,
so we add some special-case logic to recognize that.)
We can identify the "Open Recent" and "Import Recent" submenus just as
easily by looking at the value of the .id field (MNU_OPEN_RECENT and
MNU_GROUP_RECENT, respectively).
Some menu items in the menu-bar are toggles (each representing an option
that can be turned on or off independently), and some are 1-of-N selections
(e.g. mm or inches), like tuner buttons on a car radio. Windows can draw an
optional check-mark besides a menu item, and SolveSpace has been using this
feature to implement both kinds of menu items, with the backend logic
making them behave as a toggle or radio button as appropriate.
Other GUI platforms can draw proper radio-button menu items that are
distinct from toggles, however. To allow the platform-specific logic to
tell the two kinds of menu items apart, this change adds the
RadioMenuById() routine, and replaces the appropriate calls to
CheckMenuById() with it. (Note that nothing is changed in the Windows GUI
code; radio-menu items are still drawn with check-marks.)
Several MenuEntry elements in GraphicsWindow::menu[] were being initialized
with four items instead of the requisite five, due to a missing fourth
column (corresponding to the .accel field of MenuEntry). This change simply
adds zeroes as the missing column to the appropriate elements.
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.
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]
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]
default, let's do a "use perspective projection" item that's off by
default. Same meaning, but less confusion.
[git-p4: depot-paths = "//depot/solvespace/": change = 2132]
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]
exporting our view to any file that doesn't have a canvas size (and
therefore doesn't get everything shifted to fit with the requested
margins around it in the canvas).
[git-p4: depot-paths = "//depot/solvespace/": change = 2107]
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]
left-clicking always selects, and there's a special context menu
item to deselect. Also streamline the right-click behavior by
making that select the hovered item, and making all the context
menu items work on the selection.
[git-p4: depot-paths = "//depot/solvespace/": change = 2091]
selected entities, but cleared after dragging an unselected entity.
Marquee selection is select-only (not toggle), and "Select All"
replaces "Invert Selection". Left-click on nothing will clear the
selection.
Also add context menu entries for cut, copy, and paste.
[git-p4: depot-paths = "//depot/solvespace/": change = 2089]
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]
only in a workplane; but this means that plane sketches are
conveniently transformed from one plane to another.
Also tweak snap to grid to ignore unsnappable entities instead of
triggering an error, and to remove arbitrary limit on the number of
entities / comments that will be snapped.
[git-p4: depot-paths = "//depot/solvespace/": change = 2084]
because it can't be C2 continuous after splitting (since I'm
doing uniform splines only, and the parametrization changes). So
just knock everything down to cubic Beziers.
Also draw lines to indicate angle and origin when Ctrl+dragging to
rotate in plane of screen.
[git-p4: depot-paths = "//depot/solvespace/": change = 2075]
under the just-deselected coincident point when I'm working on
batches, which really could have selected that underneath point.
And always pwl curves to at least two line segments (and likewise
retain at least one intermediate point when removing short edges),
to avoid confusion when holes end up square.
[git-p4: depot-paths = "//depot/solvespace/": change = 2070]
work on hidden entities. Also fix bug where undo state wasn't saved
before toggling construction.
[git-p4: depot-paths = "//depot/solvespace/": change = 2067]
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]
to assemble Beziers into outer and inner loops, and find those
loops made up of entities with filled styles. The open paths are
maintained in a separate list, and we assemble as many closed paths
as possible even when open paths exist.
This changes many things. The coplanar check is now performed on
the Beziers, not the resulting polygon. The way that the polygon is
used to determine loop directions is also modified.
Also fix the mouse behavior when dragging a point: drop it when the
mouse is released, even if it is released outside the window, but
don't drop it if the pointer is dragged out of and then back into
our window.
Also special-case SSurface::ClosestPointTo() for planes, for speed.
[git-p4: depot-paths = "//depot/solvespace/": change = 2058]
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]
Constraint::COMMENTs), including line width and color, and text
height and origin location.
[git-p4: depot-paths = "//depot/solvespace/": change = 2033]
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]
(in my case, a SpaceNavigator). I can transform the view of the
part, or transform a part in an assembly.
Also fix up mouse wheel input, so that it works even if it comes in
chunks of less than 120 units.
[git-p4: depot-paths = "//depot/solvespace/": change = 2019]
feared. Though I don't have rational surfaces or curves going yet,
and I don't have the stuff to handle holes or multiple outer
contours in a single surface.
[git-p4: depot-paths = "//depot/solvespace/": change = 1974]
separate polygon of coincident (with same or opposite normal)
faces; I instead test all the edges against the other shell, and
have extended the classify-against-shell stuff to handle those
cases.
And the normals are now perturbed a bit numerically, to either side
of the edge, to distinguish tangency from a coincident surface.
This seems to work fairly well, although things still tend to fail
when the piecewise linear tolerance is too coarse.
[git-p4: depot-paths = "//depot/solvespace/": change = 1964]
can show edges for both meshes and shells, and export them and
hidden line remove and all the usual stuff.
And fix the zoom to fit on startup, so that it considers hidden
entities too. That avoids the problem where things get generated at
stupid chord tolerance because no entities were visible and the
mesh of course did not yet exist.
[git-p4: depot-paths = "//depot/solvespace/": change = 1961]
a mesh than that's a copy, and if we're working with a shell then
it's the shell's triangulation.
[git-p4: depot-paths = "//depot/solvespace/": change = 1957]

simplify use of the constraint solver in a library.
