- Popup footnotes: workaround strange behaviour of MuPDF
which is adding some unwanted margin above elements
with an "id=" attribute.
- In-page footnotes: also remove any left and right margin,
to keep footnotes aligned with the main text.
Also add 2 classnames (witnessed in quite a few recent
french books) to the list of classic classnames.
- Also bump crengine: CSS: fix parsing of multi classnames
and attributes selectors
- Remove duplicated "Show footnote popup". Have the same setting
applied for Tap or 'Swipe to follow nearest link'.
- Make some menu items enabled or disabled depending on if they would
have some effect with the current state of other menu items, as
some kind of visual self-documentation of these dependancies.
- Add menu item to set the footnote popup font size, relative to
the book font size.
- SpinWidget: allow for showing some informative text
When a link is covered by the footnote widget, we highlight it
again when closing the footnote, and schedule an unhighlight
0.5s later.
When we tap on another footnote link, this was happening too
but the unhighlight unhighlighted all, including the new
footnote link.
This disable the former when the latter happens.
Adds new options to the Links> submenu, for now only
available and used with CRE documents.
- Allow larger tap area around links
- Ignore external links
- Show footnotes in popup
- Show more links as footnotes
(This last item is mostly for testing and loosening the
footnote detection algorithm, and see how it would behave
with glossary-like links and inter glossary terms links.)
Fix distance computation from gesture position to link by
using segments.
Code for detecting if a link is a footnote is in cre.cpp, and
tweakable a bit with flags in ReaderLink:showAsFoonotePopup().
Footnotes HTML content is displayed by a new FootnoteWidget,
which uses MuPDF for its rendering.
From it, swipe south or tap outside to close, swipe to the left
to follow the original link and jump to the footnote location
in the book.
Also fix tap on highlights after the recent change to use segments
for displaying: use segments also when checking taps.
