The conditional formatting is extended to cover free single-cell
formatting. The row-id formats have precedence over regular conditional
formats.
In the styling toolbar, when single cells are selected, row-id formats are
created or updated. When entire columns are selected, regular conditional
formats are instead. Clearing formats for entire columns, remove both. For
single cells, only corresponding row-id formats.
New row-id formats are also saved to project files and loaded.
See issue #1976
The requested text alignment is always combined with AlignVCenter, which is
the value used before conditional formatting was implemented and gives
better display result.
When creating a new conditional formatting while applying a format from the
toolbar to a column which does not already have one, the alignment flag
of the format is taken from the current cell. In this way, the default text
alignment for numbers is preserved.
See issue #1976 and PR #2013
The new toolbar is hidden by default and can be toggled using a button in
the main Data Browser toolbar. Margins and spacing have been updated to
improve appearance of the two toolbars.
These tool buttons apply the format to the columns which are contained in
the selection. This is done by updating or adding a new condition-less
format to the list of conditional formats of those columns.
New style icons from the Silk icon set. Changed existent ones for
coherence.
See issue #1976.
Combo box for selecting the desired text alignment for a conditional
format.
The default alignment in the browser has been adjusted for numbers, which
are now aligned to the right as in spreadsheets.
Project file format updated.
See issues #1976 and #1815.
The conditional format manager allows now to set the font style: bold,
italic and underline.
The project format has been updated. This is also the base for setting
other font formats without further changing the project schema.
New icons form the Silk icon set.
See issue #1976 and #1815.
A new dialog for editing conditional formats that can be invoked from the
filter line editor or from the data browser contextual menus. The dialog
allows adding and removing conditional formats, changing the priority order
and editing foreground colour, background colour and filter condition.
The conditional formats have been expanded to allow defining the foreground
colour. By default is the setting configured by user.
This is a continuation of the functionality introduced in PR #1503.
After setting a filter, the user can select from the context menu in the
filter line a new option "Use for Conditional Format", that assigns
automatically a colour to the background of cells fulfilling that
condition.
The formatting is preserved after the user has removed the filter. Several
conditional formats can be successively added to a column using different
filters.
The conditional formats of a column can be cleared when the filter is empty
selecting "Clear All Conditional Formats" from the filter line context
menu.
The conditional formats are saved and loaded in project files as other
browse table settings.
A new class Palette has been added for reusing the automatic colour
assignment of the Plot Dock. It takes into account the theme kind of the
application (dark, light) for the colour selection.
A new class CondFormat for using the conditional formatting settings from
several classes. The conversion of a filter string from our format to an
SQL condition has been moved here for reuse in filters and conditional
formatting.
Whether the conditional format applies is resolved by SQLite, so filters
and conditional formats give the same exact results.
Code for getting a pragma value has been reused for getting the condition
result, and consequently renamed to selectSingleCell.
Possible future improvement:
- New dialog for editing the conditional formatting (at least colour and
application order of conditions, but maybe too: adding new conditions and
editing the condition itself).
