Just prevent page thumbnails ImageWidgets to be nightmode
inverted, unlike all other ones which are expected to be
double inverted to get their original colors shown.
The same thumbnail can be used and cached in both day and
night modes, unless "nightmode_images" is enabled and have
crengine itself invert images, making thumbnails different.
Checkboxes under TOC>Settings> allow enabling Custom TOC
and Custom hidden flows (similar to "Hide non-linear fragments"
available with some EPUBs).
Handled by a new ReaderHandmade module.
Adding and removing TOC chapters is done in PageBrowser
with long-press on a page thumbnail, and for chapters also
in the popup dialog after selecting some text in a page.
ReaderToc: add a symbol in title when the TOC is the
alternative TOC or the custom TOC.
When enabled in BookMap, both BookMap and PageBrowser get:
- alternating gray background on chapter spans
- hatched background instead of uni-gray on hidden flows.
Also, with both normal look and this alternative theme,
show some hatched overlay on thumbnails part of hidden flows.
ReaderToc: for each TOC item, have it carry its sequence/number
in that level (we do this in validateAndFixToc() where we are
already iterating all the items).
If originally with two-columns in page mode, and switching
to scroll mode, thumbnails generation would be slow as
the document would be rerendered for each thumbnail.
instead of doing arithmetic (ie. new_page=cur_page+1).
This makes it ready to work with custom hidden flows
where these document:getNextPage()/getPrevPage() will
be overloaded to skip pages in hidden flows.
Also fix some odd issues (page truncated or with parts
duplicated) with scrolling/page turning when at start
or end of the document.
Move as much of the state tracking as possible inside VirtualKeyboard itself.
InputDialog unfortunately needs an internal tracking of this state because it needs to know about it *before* the VK is shown, so we have to keep a bit of duplication in there, although we do try much harder to keep everything in sync (at least at function call edges), and to keep the damage contained to, essentially, the toggle button's handler.
(Followup to #10803 & #10850)
onCloseDocument is way too early, if another, later onCloseDocument
handler trips a ReaderUI repaint, a new task will be scheduled, and that
one will never be cancelled, resulting in it running post-teardown,
crashing horribly.
This was for instance very easy to trigger via KOSync.
Fix#10806
Make this a real boy, with a transient lipc handle.
And get rid of the insane 1s sleep on affected ReaderView paints,
because ouchy.
This is completely deprecated anyway, so this is entirely pointless,
and mainly to prevent implementation details from creeping into
reader.lua.
The Kindle swipe animations & physical key inversion apply *everywhere*,
so we need this accessible in the FM, too.
Move it to Navigation, which is where it already was on !Touch devices.
