* FocusManager: Fix `focus_flags` check in `moveFocusTo` (0 is truthy in Lua, can't do AND checks like in C ;).)
* FileManager+FileChooser: Pass our custom title bar directly to FileChooser (which also means we can now use FC's FocusManager layout directly).
* FileChooser/Menu: Get rid of the weird `outer_title_bar` hack, and simply take a `custom_title_bar` pointer to an actual TitleBar instance instead.
* FileManager/Menu/ListMenu/CoverMenu: Fix content height computations in `_recalculateDimen` (all the non-FM cases were including an old and now unused padding value, `self.header_padding`, leading to more blank space at the bottom than necessary, and, worse, leading to different item heights between FM views, possibly leading to unnecessary thumbnail scaling !)
* ButtonDialog: Proper focus management when the ButtonTable is wrapped in a ScrollableContainer.
* ConfigDialog: Implement a stupid workaround for a weird FocusManager issue when going back from `[⋮]` buttons.
* ConfigDialog: Don't move the visual focus in `update` (i.e., we use `NOT_FOCUS` now that it works as intended).
* DictQuickLookup: Ensures the `Menu` key bind does the exact same thing as the hamburger icon.
* DictQuickLookup: Ensure we refocus after having mangled the FocusManager layout (prevents an old focus highlight from lingering on the wrong button).
* FileChooser: Stop flagging it as no_title, because it is *never* without a title. (This behavior was a remnant of the previous FM-specific title bar hacks, which are no longer a thing).
* FileChooser: Stop calling `mergeTitleBarIntoLayout` twice in `updateItems`. We already call Menu's, which handles it. (Prevents the title bar from being added twice to the FocusManager layout).
* FocusManager: Relax the `Unfocus` checks in `moveFocusTo` to ensure we *always* unfocus something (if unfocusing was requested), even if we have to blast the whole widget tree to do so. This ensures callers that mangle self.layout can expect things to work after calling it regardless of how borked the current focus is.
* FocusManager: Allow passing `focus_flags` to `refocusWidget`, so that it can be forwarded to the internal `moveFocusTo` call.
* FocusManager: The above also allows us to enforce a default that ensures we do *not* send a Focus event on Touch devices, even if they have the hasDPad devcap. This essentially restores the previous/current behavior of not showing the visual feedback from such focus "events" sent programmatically, given the `focus_flags` check fix at the root of this PR ;).
* InputDialog: Fix numerous issues relating to double/ghost instances of both InputText and VirtualKeyboard, ensuring we only ever have a single InputText & VK instance live.
* InputDialog: Make sure every way we have of hiding the VK play nice together, especially when the `toggleKeyboard` button (shown w/ `add_nav_bar`) is at play. And doubly so when we're `fullscreen`, as hiding the VK implies resizing the widget.
* InputText: Make sure we're flagged as in-focus when tapping inside the text field.
* InputText: Make sure we don't attempt to show an already-visible VK in the custom `hasDPad` `onFocus` handler.
* Menu: Get rid of an old and no longer used (nor meaningful) hack in `onFocus` about the initial/programmatically-sent Focus event.
* Menu: Get rid of the unused `header_padding` field mentioned earlier in the FM/FC fixes.
* Menu: Use `FOCUS_ONLY_ON_NT` in the explicit `moveFocusTo` call in `updatePageInfo`, so as to keep the current behavior of not showing the visual feedback of this focus on Touch devices.
* Menu: Make sure *all* the `moveFocusTo` calls are gated behind the `hasDPad` devcap (previously, that was only the case for `updatePageInfo`, but not `mergeTitleBarIntoLayout` (which is called by `updateItems`).
* MultiInputDialog: Actively get rid of the InputText & VK instances from the base class's constructor that we do not use.
* MultiInputDialog: Ensure the FocusManager layout is *slightly* less broken (password fields can still be a bit weird, though).
* TextViewer: Get rid of the unfocus -> layout mangling -> refocus hack now that `refocusWidget` handles this case sanely.
* VirtualKeyboard: Notify our parent InputDialog when we get closed, so it can act accordingly (e.g., resize itself when `fullscreen`).
* ScrollableContainer: Implement the necessary machinery for focus handling inside ButtonDialog (specifically, when scrolling via PgUp/PgDwn).
* TextEditor: Given the above fixes, the plugin is no longer disabled on non-touch devices.
* ReaderBookMark: Make sure we request a full refresh when closing the "Edit note" dialog, as CRe highlights may extend past its dimensions, and if it's closed separately from VK, the refresh would have been limited to its own dimensions, leaving a neat InputDialog-sized hole in the highlights ;).
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)
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.

Allow TextBoxWidget new text direction/lang parameters to be
set on upper widgets, and propagate them all the way to it
(ScrollTextWidget, InputText, InputDialog, TextViewer).
Use specific non-default ones in some specific cases:
- Force LTR text direction when showing HTML and CSS, and
configuration files (in some plugins).
- Use Wikipedia server language and text direction when
showing an article.
- Use auto with Dictionary results, as we don't know the
dictionary language, and they may contain mixed content.
- Force LTR when showing some paths (still needs more of them)
TextEditor plugin: add 2 new options "Auto paragraph direction"
and "Force paragraph direction LTR".
Footnotes popup: grab HTML direction, and forward it
to MuPDF for proper display.
* Various FocusManager related tweaks to limit its usage to devices with a DPad, and prevent initial button highlights in Dialogs on devices where it makes no sense (i.e., those without a DPad. And even on DPad devices, I'm not even sure how we'd go about making one of those pop up anyway, because no Touch ;)!).
* One mysterious fix to text-only Buttons so that the flash_ui highlight always works, and always honors `FrameContainer`'s pill shape. (Before that, an unhighlight on a text button with a callback that didn't repaint anything [say, the find first/find last buttons in the Reader's search bar when you're already on the first/last match] would do a square black highlight, and a white pill-shaped unhighlight (leaving the black corners visible)).
The workaround makes *absolutely* no sense to me (as `self[1] -> self.frame`, AFAICT), but it works, and ensures all highlights/unhighlights are pill-shaped, so at least we're not doing maths for rounded corners for nothing ;).
* Enable HW dithering on supported devices (Clara HD, Forma; Oasis 2, PW4)
* FileManager and co. (where appropriate, i.e., when covers are shown)
* Book Status
* Reader, where appropriate:
* CRe: on pages whith image content (for over 7.5% of the screen area, should hopefully leave stuff like bullet points or small scene breaks alone).
* Other engines: on user-request (in the gear tab of the bottom menu), via the new "Dithering" knob (will only appear on supported devices).
* ScreenSaver
* ImageViewer
* Minimize repaints when flash_ui is enabled (by, almost everywhere, only repainting the flashing element, and not the toplevel window which hosts it).
(The first pass of this involved fixing a few Button instances whose show_parent was wrong, in particular, chevrons in the FM & TopMenu).
* Hunted down a few redundant repaints (unneeded setDirty("all") calls),
either by switching the widget to nil when only a refresh was needed, and not a repaint,
or by passing the appropritate widget to setDirty.
(Note to self: Enable *verbose* debugging to catch broken setDirty calls via its post guard).
There were also a few instances of 'em right behind a widget close.
* Don't repaint the underlying widget when initially showing TopMenu & ConfigDialog.
We unfortunately do need to do it when switching tabs, because of their variable heights.
* On Kobo, disabled the extra and completely useless full refresh before suspend/reboot/poweroff, as well as on resume. No more double refreshes!
* Fix another debug guard in Kobo sysfs_light
* Switch ImageWidget & ImageViewer mostly to "ui" updates, which will be better suited to image content pretty much everywhere, REAGL or not.
PS: (Almost 💯 commits! :D)
This plugin mostly sets up a "Text editor>" submenu, that allows
browsing files, creating a new file, and managing a history of
previously opened file for easier re-opening.
It restore previous scroll and cursor positions on re-opening.
Additional "Check lua" syntax button is added when editing
a .lua file, and prevent saving if errors.
The text editing is mainly provided by the enhanced InputDialog.
InputDialog: added a few more options, the main one being
'save_callback', which will add a Save and Close buttons
and manage saving/discarding/exiting.
If "fullscreen" and "add_nav_bar", will add a show/hide keyboard
button to it.
Moved the preset buttons setup code in their own InputDialog
methods for clarity of the main init code.
Buttons are now enabled/disabled depending on context for feedback
(eg: Save is disabled as long as text has not been modified).
Added util.checkLuaSyntax(lua_string), might be useful elsewhere.
* [VirtualKeyboard] Add support for keynaviguation
Also rename the variable "layout" to "keyboard_layout" because conflict
with the layout from the focusmanager
* Make the goto dialog compatible with key naviguation
My solution is to change the order of the widget. The last one will the
virtualkeybard so it catch all the keybinding, and below it, make the
dialog "is_always_active = true" so it can receive touch event.
* Correctly show the virtual keyboard on dpad devices
* change the order to call the virtualKeyboard so it end up on top
* Handle the multi input dialog
* Support reopening the virtualKeyboard by the Press key
* add check focusmanager
* Fix https://github.com/koreader/koreader/issues/3797
* MultiInputDialog : Now work on non touch-device
* Set the virtualkeyboard to be a modal widget
* Fix the layout in multiinputwidget
* Fix for the various combination of
hasKeys,hasDpad,isTouchDevice
* [Focusmanager] Better handling of malformed layout
This makes button heights similar in all uses of ButtonTable.
It depended on how the ButtonTable was used in each widget
(previously, first and last row may have different sizes than
the others).
buttontable.lua: more even buttons height whether zero_sep or not
framecontainer.lua: added padding_top/bottom/left/right (similar to
what was done for iconbutton)
The following widgets have been adapted for this, with some
additional fixes:
buttondialog.lua
buttondialogtitle.lua: wider title with adequate padding
confirmbox.lua + multiconfirmbox.lua: dismissable via tap outside
inputdialog.lua + multiinputdialog.lua: more even vertical padding between elements
imageviewer.lua
textviewer.lua
datewidget.lua
timewidget.lua
Additionaly: frontlightwidget.lua: fixed width of progress bar that
was exceeding window width since the Size scaling adjustements
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.
colors were a mixture of 4bpp integers (0=white, 15=black) and
fractional blackness levels (0=white, 1.0=black) before. This is
now unified to use the color specification of the Blitbuffer API.
