Namely, don't recompute layouts, as they do not change.
(The gyro codepaths were already doing something similar.)
* Keep ConfigDialog, FileManagerMenu & ReaderMenu open on rotation.
(In practice, only ConfigDialog is affected, as *Menu doesn't handle the rotation event.)
* Plugged an instance leak in the aforementioned Menu classes.
* Unify behavior & code with the gyro codepaths.
None[1] of them actually rely on their own onGesture handler, they
all register their own stuff to ReaderUI's.
Hotfix #9710 revealed that the way this was handled didn't exactly
work as expected ;).
The only thing that consumes ges_events is InputContainer's onGesture
method. All these modules *extend* InputContainer, but none of them
*implement* a custom onGesture, so self.onGesture = nil was just a NOP,
they always access InputContainer's method via inheritance.
If we actively want to neuter it, we *have* to implement it in that
module (with a NOP).
[1] The exception being ReaderZooming, but that only when in flip mode.
Get rid of the doc & seqtext fields, as they are not actually used (nor
are they particularly useful, the event handler's name should be pretty
self-explanatory).
Also, tweak the key_events documentation to highlight the quirks of the
API, especially as far as array nesting is involved...
Random drive-by cleanup of the declarations of key_events & ges_events
to re-use the existing instance object (now that we know they're sane
;p) for tables with a single member (less GC pressure).
Basically:
* Use `extend` for class definitions
* Use `new` for object instantiations
That includes some minor code cleanups along the way:
* Updated `Widget`'s docs to make the semantics clearer.
* Removed `should_restrict_JIT` (it's been dead code since https://github.com/koreader/android-luajit-launcher/pull/283)
* Minor refactoring of LuaSettings/LuaData/LuaDefaults/DocSettings to behave (mostly, they are instantiated via `open` instead of `new`) like everything else and handle inheritance properly (i.e., DocSettings is now a proper LuaSettings subclass).
* Default to `WidgetContainer` instead of `InputContainer` for stuff that doesn't actually setup key/gesture events.
* Ditto for explicit `*Listener` only classes, make sure they're based on `EventListener` instead of something uselessly fancier.
* Unless absolutely necessary, do not store references in class objects, ever; only values. Instead, always store references in instances, to avoid both sneaky inheritance issues, and sneaky GC pinning of stale references.
* ReaderUI: Fix one such issue with its `active_widgets` array, with critical implications, as it essentially pinned *all* of ReaderUI's modules, including their reference to the `Document` instance (i.e., that was a big-ass leak).
* Terminal: Make sure the shell is killed on plugin teardown.
* InputText: Fix Home/End/Del physical keys to behave sensibly.
* InputContainer/WidgetContainer: If necessary, compute self.dimen at paintTo time (previously, only InputContainers did, which might have had something to do with random widgets unconcerned about input using it as a baseclass instead of WidgetContainer...).
* OverlapGroup: Compute self.dimen at *init* time, because for some reason it needs to do that, but do it directly in OverlapGroup instead of going through a weird WidgetContainer method that it was the sole user of.
* ReaderCropping: Under no circumstances should a Document instance member (here, self.bbox) risk being `nil`ed!
* Kobo: Minor code cleanups.
* This removes support for the following deprecated constants: `DTAP_ZONE_FLIPPING`, `DTAP_ZONE_BOOKMARK`, `DCREREADER_CONFIG_DEFAULT_FONT_GAMMA`
* The "Advanced settings" panel now highlights modified values in bold (think about:config in Firefox ;)).
* LuaData: Isolate global table lookup shenanigans, and fix a few issues in unused-in-prod codepaths.
* CodeStyle: Require module locals for Lua/C modules, too.
* ScreenSaver: Actually garbage collect our widget on close (ScreenSaver itself is not an instantiated object).
* DateTimeWidget: Code cleanups to ensure child widgets can be GC'ed.
- FocusManager: allow managing sub widgets by merging their
"layout" in the main one; make "press" support simpler by
handling it as a fake tap event at the center of the
focused widget.
- Setup gestures on non-touch devices for new focus manager.
- ToggleSwitch: use child layout.
- ButtonProgressWidget: use child layout.
- SpinWidget and DoubleSpinWidget: add keyboard navigation.
Add a new reader module: ReaderScrolling, that exposes
some Scrolling options to the menu (which are to be used
by and implemented in ReaderPaging and ReaderRolling
themselves) and implement some inertial scrolling logic
used by both of them.
Default to "Classic scrolling" which is the expected
behaviour on phones and tablets.
The old CreDocument buggy behaviour is available as
"Turbo scrolling" for both Paging and Rolling documents.
Added a "On release scrolling" option that might be
useful on eInk to avoid dynamic pan/scrolling.
Try to avoid bad interactions between pan and swipe,
cancelling unwanted panning if we ended up doing a
swipe or multiswipe.
* LuaSettings/DocSettings: Updated readSetting API to allow proper initialization to default.
Use it to initialize tables, e.g., fixing corner-cases in readerFooter that could prevent settings from being saved.
(Fixes an issue reported on Gitter).
* LuaSettings/DocSettings: Add simpler API than the the flip* ones to toggle boolean settings.
* Update LuaSettings/DocSettigns usage throughout the codebase to use the dedicated boolean methods wher appropriate, and clean up some of the more mind-bending uses.
* FileChooser: Implement an extended default exclusion list (fix#2360)
* ScreenSaver: Refactor to avoid the pile of kludges this was threatening to become. Code should be easier to follow and use, and fallbacks now behave as expected (fix#4418).
* Top menu & bottom menu tapzones are now full-width, thanks to the now sane override system.
* A separate, extra tapzone was also created for each of them to provide a taller, but narrower tapzone extension (one that doesn't clash with the prev/next tapzones).
* The footer tapzone was made much taller.
- ReaderConfig does not need to call again self:initGesListener() on
screen rotation/resize, as it uses the TouchZone infrastructure
that deals itself with rotation. So, it was adding new gestures
that were overriding tap on footer and preventing it from working.
- ReaderFooter: fix refresh area (which was too small when toggling
from hidden to visible)
- ReaderToc: fix crash when showing TOC in scroll mode after rotation
- Menu: fix crash when no onReturn defined (could happen when tap on
bottom left corner when showing an empty TOC)
* [toggleswitch] Add support for key navigation to this widget
Add the onFocus an onUnfocus event handler
add a new function that just circle the switch if not touch event is
detected
* Add key navigation to the readermenu
The shortcut is still Alt-gr on sdl, to be defined on Kindle
* Remove the old method of handling the Press key.
Now the event is handled by the main widget who implement focusmanager
and then dispatched to the currently focused item.
Modify the fine font tuning only for non touch-devices
See : https://github.com/koreader/koreader/pull/3785#issuecomment-375306466
Reading an epub file with Mupdf would show 6 items in bottom
config panel. Reading it with crengine would show only 5.
A crash would happen if we were on the 6th when leaving MuPDF,
and later opening config panel with crengine.
"partial" refresh causes a full (without black flash) refresh on
Kindle (which uses REAGL mode for partial refresh). This causes a
full redraw of widgets, which is a bit distracting with some of them:
- dictquicklookup: when showing next definition
- infomessage: when displaying a new one (Wikipedia Save as epub)
Also fix bottom menu, that even when closed, would still register
bottom area as dirty: this would cause top menu navigation to
cause a full partial refresh, only noticable on Kindle.
Without this fix, self.dimen is shared among all inputcontainers
intances, which breaks some of the UI rendering. All widget should
set/initialize their own self.dimen in self:init() method.
This is a major overhaul of the hardware abstraction layer.
A few notes:
General platform distinction happens in
frontend/device.lua
which will delegate everything else to
frontend/device/<platform_name>/device.lua
which should extend
frontend/device/generic/device.lua
Screen handling is implemented in
frontend/device/screen.lua
which includes the *functionality* to support device specifics.
Actually setting up the device specific functionality, however,
is done in the device specific setup code in the relevant
device.lua file.
The same goes for input handling.
