@ -66,62 +66,11 @@ drawing from metrics.
Other changes are only clean-ups. Other changes are only clean-ups.
** DONE RowPainter
Inset position is set in paintInset, paintOnlyInsets, and paintText.
This should be done only once in paintInset
** DONE TextMetrics::drawParagraph
We can really simplify the code when drawing is disabled only
paintInset needs to be called.
+ do right at the start when drawing is already disabled
+ do it in the loop for rows that are not visible on screen.
The only thing we want to do here is to set inset positions (for
text). The other insets still use the painter with drawing disabled.
** DONE Painter::text
We cannot remove (or make private) the version that uses a
FontInfo because it is used by PainterInfo::draw. Document this and
remove unused arguments rtl and double spacing. This would become a specialized helper.
Proposed solution: keep the existing function, but private and without
optional arguments.
Avoid to return (and thus compute) the width of strings?
+ used by InsetSpecialChar (fixable)
+ used by textDecoration() in text(): more difficult to fix
Idea: add a version of text where wordspacing and textwidth (giving
the width of strings) are required parameters and remove optional
version.
==> more versions, no optional parameters.
** DONE When a document ends with a newline, add the bottom margin anyway
The code that tests for a newline was added at 6bb98d07 in 2007.
** When a paragraph ends with a newline, compute correctly the height of the extra row. ** When a paragraph ends with a newline, compute correctly the height of the extra row.
** Rewrite TextMetrics::editXY, checkInsetHit using row information (getPosNearX)? ** Rewrite TextMetrics::editXY, checkInsetHit using row information (getPosNearX)?
The helper version should return a Row::Element instead of an InsetTable. The helper version should return a Row::Element instead of an InsetTable.
** DONE Do not make RowPainter operations update x_
It is better to make them const and update x_ separately.
** DONE remove pit argument to breakRow
There are probably other places where the pit is not needed anymore:
computeRowMetrics, labelFill, setRowHeight, isLastRow, isFirstRow
** DONE Split setRowHeight to separate the computation of space above/below paragraph
This allows to remove the topBottomSpace parameter. The spacing is
computed in redoParagraph, where it feels more natural.
** Remember rtl status in the row object ** Remember rtl status in the row object
This will avoid to pass a Paragraph object to methods that do not need it. This will avoid to pass a Paragraph object to methods that do not need it.
