Implement modifying the current selection programmatically via the
ViewProvider object in both C++ and Python. This enables unit testing of
GUI tasks that require a selection, and improves scriptability of
Spreadsheet.
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.
The two line edit widgets above the spreadsheet, one for exiting the
cell contents and one for editing the alias, were set to use the same
editing widget as the individual spreadsheet cells. Once that widget was
refactored to handle tab/enter behavior it was no longer the correct
widget for those elements. This commit changes them to
Gui::ExpressionLineEdit widgets instead, so that the Enter key works
correctly for them again.
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).
* Add support for better translations (using pluralizations)
* Add support for inserting rows/columns after the selection
* Informs the user that it will insert rows/cols above/under/left/right of the selection
* Informs the user how many rows/cols that will be inserted
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
After pull request https://github.com/FreeCAD/FreeCAD/pull/4215 it
doesn't make much sense helping the user to write expressions without
leading '=', as that content will be parsed as a string.
This change adjusts the behaviour in SpreadsheetGui's LineEdit to avoid
popping up the ExpressionCompleter when no leading equal sign is used.
There are no reason to check the return values for these functions
as the string passed as an argument will be set to an empty string
if it false. An empty string is a valid option in these instances.
Coverity warnings fixed:
CID 316520 (1 of 1): Unchecked return value (CHECKED_RETURN)
3. check_return: Calling getAlias without checking return value (as is done elsewhere 8 out of 10 times).
CID 316557 (1 of 1): Unchecked return value (CHECKED_RETURN)
8. check_return: Calling getAlias without checking return value (as is done elsewhere 8 out of 10 times).
