No longer add dynamic property for alias, simply rely on
get(Dynamic)PropertyByName() to check for aliases.
Add new API PropertyContainer::getPropertyNamedList() so that
ExpressionCompleter can discover properties with aliases.
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
LineEdit no longer actually handles motion, it simply indicates which
action was taken to cause it to lose focus (e.g. which key was pressed).
It's up to the client code to determine what this means. This allows
significant consolidation of keyboard-handling logic, and the
implementation of more extensive keyboard navigation features.
New keyboard shortcuts include a tab counter to implement auto-return,
plus Ctrl->Arrow, End, Home, Ctrl-End, and Ctrl-Home, matching the
behavior of OpenOffice, LibreOffice, etc.
Block selection via keyboard has also been added by holding down the
shift key during navigation with the arrow keys (this also works in
combination with the Ctrl modifier for region navigation).
PropertySheet is changed to derive from PropertyExpressionContainer,
which makes it a link type property that is capable of external linking.
It now relies on the unified link property API to manage object
depenency, and tracking of object life time, relabeling, etc.
This patch also includes various fix and improvement of Spreadsheet,
such as improved recompute efficiency, correct handling of document
label change, etc.
- 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.
