Convenience helpers function Tools::toStdString and Tools::fromStdString
were implemented for Qt4 or older to perform utf8 aware conversion as
QString::toStdString/QString::fromStdString were using toAscii/fromAscii
internally (see https://dreamswork.github.io/qt4/classQString.html).
Since Qt5 QString uses toUtf8/fromUTf8, which makes the helper functions
obsolete (see https://doc.qt.io/qt-5/qstring.html#fromStdString).
The recent migration from boost::bind to std::bind [1] broke the build
on Mac (Apple clang version 13.0.0 (clang-1300.0.29.30) on macOS-11.7.8).
In all other cases the `boost::bind` was replaced by `std::bind` (among
with the place holders) but in these two spread sheet files
src/Mod/Spreadsheet/Gui/SheetModel.cpp
src/Mod/Spreadsheet/Gui/SpreadsheetView.cpp
the original code only referenced `bind`, which used to get resolved to
`boost::bind` but now raises this error:
> /Users/jonas/src/FreeCAD/FreeCAD-git/src/Mod/Spreadsheet/Gui/SheetModel.cpp:50:36: error: use of undeclared identifier 'bind'; did you mean 'boost::bind'?
> sheet->cellUpdated.connect(bind(&SheetModel::cellUpdated, this, sp::_1));
> ^~~~
> boost::bind
This commit changes this to `std::bind` expicitly, just like it's done in
the other files. This works on my system/compiler.

Cell binding allows one to bind a range of cells of one sheet to another
range of cells of an arbitary sheet, including any empty cells in the
range.
The binding is implemented with PropertyExpressionEngine and
PropertySheet::setPathValue(), which binds a special path of
PropertySheet, such as
.cells.Bind.A1.D1
to an expression, such as
tuple(.cells, <<A2>>, <<A5>>)
The A1 and D1 in the example above specifies the binding start and end
cell address. And <<A2>> and <<A5>> are the range of cells to bind to.
Note that you can use any expression that evalutes to string for the
binding destination, e.g. <<A%d>> % B1, which uses the value inside B1
to construct the binding destination. The '.cells' in the tuple shown
above is an example to bind cells of the same PropertySheet. It can be
change to to reference to any other spreadsheet, even those outside the
current document, e.g. Document#Spreadsheet001.cells
If recomputes are turned off, the old behavior was that a cell would
display its old property value in the SheetView. The new behavior is
that we check to see if the value is actually something that gets
computed: if so, show "#PENDING". If not, display the new value, but
format it specially to indicate that it's been changed and that
a recompute is (eventually) needed.
Qt has deprecated the following constants, this commit replaces them
with their new equivalent/replacement:
Qt::TextColorRole -> Qt::ForegroundRole
Qt::BackgroundColorRole -> Qt::BackgroundRole
QPainter::HighQualityAntialiasing -> QPainter::Antialiasing
QPalette::Foreground -> QPalette::WindowText
- Refactoring/clean-up of code
- Dependency tracking of aliased cells
- Various resolution errors
- Rewriting of ranges when columns/rows are inserted/removed
- References to aliases keep their units.
