* QuickDictLookup, ImageViewer, NumberPicker: Smarter `update` that will re-use most of the widget's layout instead of re-instantiating all the things.
* SpinWidget/DoubleSpinWidget: The NumberPicker change above renders a hack to preserve alpha on these widgets almost unnecessary. Also fixed said hack to also apply to the center, value button.
* Button: Don't re-instantiate the frame in setText/setIcon when unnecessary (e.g., no change at all, or no layout change).
* Button: Add a refresh method that repaints and refreshes a *specific* Button (provided it's been painted once) all on its lonesome.
* ConfigDialog: Free everything that's going to be re-instatiated on update
* A few more post #7118 fixes:
* SkimTo: Always flag the chapter nav buttons as vsync
* Button: Fix the highlight on rounded buttons when vsync is enabled (e.g., it's now entirely visible, instead of showing a weird inverted corner glitch).
* Some more heuristic tweaks in Menu/TouchMenu/Button/IconButton
* ButtonTable: fix the annoying rounding issue I'd noticed in #7054 ;).
* Enable dithering in TextBoxWidget (e.g., in the Wikipedia full view). This involved moving the HW dithering align fixup to base, where it always ought to have been ;).
* Switch a few widgets that were using "partial" on close to "ui", or, more rarely, "flashui". The intent being to limit "partial" purely to the Reader, because it has a latency cost when mixed with other refreshes, which happens often enough in UI ;).
* Minor documentation tweaks around UIManager's `setDirty` to reflect that change.
* ReaderFooter: Force a footer repaint on resume if it is visible (otherwise, just update it).
* ReaderBookmark: In the same vein, don't repaint an invisible footer on bookmark count changes.
Also adds options to remove statistics for books
with low reading duration (to clean up stats for
books just quickly browsed and not yet read).
Also adds TextWidget:getFontSizeToFitHeight()
even if we ended up not using it.
A few fixes and enhancement related to bold text:
- When using bold=true with a regular font, use its bold
variant if one exists (can be prevented by manually
adding a setting: "use_bold_font_for_bold" = false).
- When using a bold font without bold=true, promote bold
to true, so fallback fonts are drawn bold too.
- Whether using a bold font, or using bold=true, ensure
fallback fonts are drawn bold, with their available bold
variant if one exists, or with synthetized bold.
- When using a bold variant of a fallback font, keep using
the regular variant as another fallback (as bold fonts
may contain less glyphs than their regular counterpart).
- Allow providing bold=Font.FORCE_SYNTHETIZED_BOLD to
get synth bold even when a bold font exists (might be
interesting to get text in bold the same width as the
same text non-bold).
- Use the font realname in the key when caching glyphs,
instead of our aliases (cfont, infont...) to avoid
duplication and wasting memory.
Alternative code to size and draw text with the help
of the xtext Lua C module.
Enabled by default (can be disabled via an added menu
item in "Developer options").
New properties can be specified by calling widgets, only
used when xtext is used:
- lang: use specified language instead of the UI language
- para_direction_rtl: true/false to override the default
direction for the UI language
- auto_para_direction: detect direction of each paragraph
in text
Lots of code was doing some renderText calls to get the size
of some text string, and truncate it to some width if needed,
with or without an added ellipsis, before instantiating
a TextWidget with that tweaked text string.
This PR fixes/adds some properties and methods to TextWidget
so all that can be done by it. It makes the calling code
simpler, as they don't need to use RenderText directly.
(Additionally, when we go at using Harfbuzz for text rendering,
we'll just have to update or replace textwidget.lua without
the need to update any higher level code.)
Also:
- RenderText: removed the space added by truncateTextByWidth
after the ellipsis, as it doesn't feel needed, and break
right alignment of the ellipsis with other texts.
- KeyValuePage: fix some subtle size and alignment issues.
- NumberPickerWidget: fix font size (provided font size was
not used)
* Add a toggle to disable the C blitter in the Dev menu (depends on https://github.com/koreader/koreader-base/pull/882) (never shown if the JIT is disabled, grayed out if the C blitter is not installed)
* Fix a few sizeUtf8Text call sites that were doing a nil check in order to account for the new return type.
* Tweak statusbar handling to avoid spurious sizeUtf8Text warnings when it's hidden, and unify its behavior between being hidden via toggle, and hidden on book open (at least when all-at-once is not enabled).
* c.f., https://github.com/koreader/koreader-base/pull/882 (Android, PB, RGB32 & Legacy Kindle regression fixes).
* 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
- css tweaks: use correct CSS "hyphens:" instead of "hyphenate:"
- screenshoter: more logical order of lines (no change in what it does)
- textviewer: make diagonal swipe really trigger a full refresh
- textwidget: more adequate text length to help with centering
- toggleswitch: fix sizing & centering with correct calculations
(this reduces a bit the size of switches, and may cause a new
truncation in some translations)
Decide baseline vertical position according to font metrics, instead
of the hardcoded 0.7 (in textwidget, which made the text a little
bit up in its box), and 0.75 (in toggleswitch, which made the text a
little bit down in its box). This usually gives a value around 0.72
or 0.73 with our ui fonts, which looks about right.
ReaderFooter: add bottom padding, now that our text goes a few pixels lower
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.
