Companion PR to https://github.com/koreader/koreader-base/pull/884
* Basically flags devices known to be stable when using PxP inversion.
* Plus, random fix for #4870 ;).
* A few FrontLight tweaks & cleanups on Kobo:
* Moved the Kobo-specific startup status insanity to Kobo-specific init
* Made turnOff/turnOn frontlight do a smooth ramp down/up
* On Kobo, use turnOff/turnOn for suspend/resume, to get that smooth toggle
* On Kobo, for NaturalLight w/ a mixer, only set warmth for setWarmth, and only set Brightness for setBrightness, otherwise, it tried to set both with not in-sync values, which made the FL widget jittery.
* Fix the "Enable debug logging" checkbox so that it properly disables "Enable verbose debug logging" when it gets disabled
* Avoid asking ImageWidget for alpha-blending when it's not useful
* Make ImageWidget's alpha-blending code-path double-check that alpha-blending actually is needed, and avoid it if possible
* In the same vein, only do alpha-blending in textboxwidget when absolutely necessary
* Prefer color constants over the gray() method, ensuring that they're part of the eInk palette
Depends on https://github.com/koreader/koreader-base/pull/853Fix#4774
* 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 ;).
Feature of ScrollTextWidget, only used for now by TextEditor.
Pan is like Swipe, but wait a bit at end of gesture to release:
the line on which Pan was started will be moved to where Pan is
released.
May conflict with MovableContainer (so not enabled for DictQuickLookup,
where it could have been nice - but it would work only with text
dictionaries, not with HTML ones, as ScrollHtmlWidget can't really
do that).
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.
InputText: checks whether provided content can be given
back unaltered, which may not be the case after it is
splitted to UTF8 chars if the text is binary content.
Prevent editing text if that is the case.
Adds InputText and InputDialog :isEditable() and :isEdited()
methods.
Also accounts for the scrollbar width when measuring text
to prevent it from being displayed when not needed.
Also ensure a minimal size of the scrollbar thumb so it is
rendered when huge text with many lines is displayed.
Virtual keyboard: Hold on Backspace: delete from cursor
to start of line instead of clearing all text content.
InputText, ScrollTextWidget, TextBoxWidget:
- proper line scrolling when moving cursor or inserting/deleting text
to behave like most text editors do
- fix cursor navigation, optimize refreshes when moving only the cursor,
don't recreate the textwidget when moving cursor up/down
- optimize refresh areas, stick to "ui" to avoid a "partial" black
flash every 6 appended or deleted chars
InputText:
- fix issue when toggling Show password multiple times
- new option: InputText.cursor_at_end (default: true)
- if no InputText.height provided, measure the text widget height
that we would start with, and use a ScrollTextWidget with that
fixed height, so widget does not overflow container if we extend
the text and increase the number of lines
- as we are using "ui" refreshes while text editing, allows refreshing
the InputText with a diagonal swipe on it (actually, refresh the
whole screen, which allows refreshing the keyboard too if needed)
ScrollTextWidget:
- properly align scrollbar with its TextBoxWidget
TextBoxWidget:
- some cleanup (added new properties to avoid many method calls), added
proxy methods for upper widgets to get them
- reordered/renamed/refactored the *CharPos* methods for easier reading
(sorry for the diff that won't help reviewing, but that was needed)
InputDialog:
- new options:
allow_newline = false, -- allow entering new lines
cursor_at_end = true, -- starts with cursor at end of text, ready to append
fullscreen = false, -- adjust to full screen minus keyboard
condensed = false, -- true will prevent adding air and balance between elements
add_scroll_buttons = false, -- add scroll Up/Down buttons to first row of buttons
add_nav_bar = false, -- append a row of page navigation buttons
- find the most adequate text height, when none provided or fullscreen, to
not overflow screen (and not be stuck with Cancel/Save buttons hidden)
- had to disable the use of a MovableContainer (many issues like becoming
transparent when a PathChooser comes in front, Hold to paste from
clipboard, moving the InputDialog under the keyboard and getting stuck...)
GestureRange: fix possible crash (when event processed after widget
destruction ?)
LoginDialog: fix some ui stack increase and possible crash when switching
focus many times.
* [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
* [device][kindle4] add fake event to kindle4
* modify focusmanager to allow for more complex layout
The focusmanager now naviguate the layout by avoiding nil value
instead of relying on table lenght. It should be completely backward
compatible
* add Dpad naviguation to the touchmenu
* fix crash because virtualkeyboard on non touch device
the kindle4NT has no keyboard nor touch, the fix open the virtual
keyboard so koreader dont crash but it's not useable
* Enable device with keys to use the touchmenu
* Don't get stuck in reader progress statistics plugin
* [underlinecontainer] Fix and remove unused function
References #1898.
* Prevent open screensaver more than one in the same time
* Add option to enable/disable background in message screensaver
* fallback to random images if this book cover is excluded feature + fix Disabled (leave screen/page as it is)
* Autostretch disable by default, more fallback options, leave screen as it is
And fix several other bugs introduced in #2028:
1. hint messages are back instead of the "Demo hint"
2. cursor now only presents in the focused inputbox in a multiinput dialog
3. moving cursor now works in multiinput dialog
More closely matches native behavior on REAGL devices.
Closing those widgets should still trigger a partial refresh though,
because we usually get back to the reader, and text, so we want REAGL
;).
This is a larger clean-up of the refresh situation.
The general shift is that refreshes are now mainly triggered by
the (top-level) widgets when they get shown or closed via UIManager.
All refreshes for the widgets when they are in use were handled by
themselves before. This adds the case of showing/closing.
It is the desired result of not having UIManager:show()/:close()
do (full screen) refreshes on its own.
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.
The "My Clipping" file that storing highlights and notes for Kindle
native readers could also be parsed and exported. The parser is
implemented in `evernote.koplugin/clip.lua`.
Parsed highlights and notes in one book will be packed and rendered
into html node with a slt2 template `note.tpl` that complies with
evernote markup language(ENML).
Finally the evernote client will create or update note entries and
push them to Evernote cloud.
