Raw Normal View History

Changes in preparation for the release of SolveSpace under the GPL, to add that license, and change all copyright notices to me, not Useful Subset, LLC. [git-p4: depot-paths = "//depot/solvespace/": change = 2211]

Add a screen to edit the view parameters; scale, translation, 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.

#include "solvespace.h"
Rewrite declarations of form f(void) as f(). In C++ there is no difference and newly added functions are all declared as f(), so this brings back consistency.

Replace NameStr with std::string. 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.

Use C99 integer types and C++ boolean types/values 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

Don't calculate halfRow for ShowEditControl manually. 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.

Added const qualifiers to edit-control string handling 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.
