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.
