* In ReaderPaging, the panning step pre-PanningUpdate can be wildly overshot near page edges, so, use the corrected value instead by recomputing it after the panning has been effectively computed by ReaderView.
This fixes slight inaccuracies, as well as glaring mistakes when going backwards, or when near page edges.
This is in line with how ReaderRolling computes the value, which I only realized later because I'm an idiot.
* Minor cleanups around the handling of the dim_area Geom object in general.
* Fix the "Arrow" page overlap mode to be painted in the right coordinates when going backward. Issue might not have been terribly clear because of the previous issue ;).
* Center the arrow's point, while we're here.
* Don't use AlphaContainer to make it translucent, because AlphaContainer is horribly broken, and has weird quirks and behavior that make no sense to me unless some very specific and unlikely constraints are met, and they definitely aren't here.
This fixes the arrow copying an arrow-sized square of the original page the book was opened on on the top-left corner of *every* page with an arrow. (lol).
* Do real proper alpha-blending via Icon/ImageWidget from the original icon, instead of faking it via addBlitFrom, in order to avoid the dimming *around* the triangle's shape.
Make Notification have toast=true, and UIManager deal
specifically with such widget:
a "toast" widget gets closed by any event, and let
the event be handled by a lower widget.
This should allow us to not wait or tap to get rid
of a notification, and just go on with what we're
doing.
Also make them have a default timeout of 2s,
used with all existing ones.
- Move zoom options from top menu to bottom config
- Add option to manually define zoom (relative to
page width) and overlap (in percent)
- Add options to zoom to columns or rows, possibly
with overlap. Add panning direction options when
page forward in these modes
Add option to hide (skip) non-linear fragments, only working
in 1-page mode. Tweaks mostly to footer, toc and skim code
to make it clear(er) which pages belong to linear or non-linear
fragments.
Have ReaderBack be the sole handler of onBack.
Add 4 mutually exclusive options for the Back key,
to avoid ReaderLink and ReaderBack location stacks
from interfering (ReaderBack's stack being always a
superset of ReaderLink's stack).
So, remove "Enable back history", which is replaced
by Back option "Go to previous read page".
Fix a few possible crashes and inconsistencies (when
zoom, scroll or reflow have changed) with ReaderPaging
and ReaderView when restoring previous page/view.
This is a quick exploration into how the new Device:hasFewKeys() method could work to make things more usable on very limited devices.
In the reader, the right is repurposed to open the menu. Left in turn closes it.
The same principle is applied to ButtonDialog. This means you can select anything in principle, but once you go right you can't go back.

Small tweaks all around to handle UI mirroring:
- swap existing symbols like arrows, or use alternative ones
- rotate some images, like chevrons and dogear icons
- flip some left and right swipe handling
- flip some geometry arithmetic like tap on left or right
side of page or dict window
- use new ProgressWidget:getPercentageFromPosition() instead
of geometry arithmetic
- BD.wrap() some concatenated string bits, like in reader
and menu footers
- flip inverse_reading_order when UI is mirrored
More specific tweaks:
- ReaderGesture: reset some specific gestures when UI direction
has changed (tap on top/bottom left/right corners, for
bookmarks and FileManager "Plus menu").
- ReaderRolling: show markers on the correct side of page,
in single or dual page mode.
- KoptOptions: swap left and right icons in Alignment toggle
- CheckMark: proper rendering in all 4 mirroring/rtl combinations.
- VirtualKeyboard: forbid any mirroring
- Move util.getMenuText into Menu.lua
closes#5612
the change in `ReaderView:recalculate()` causes the viewable page size to be calculated by not including the footer, causing the text not to get cut off.
since the page area was not drawing under the footer `ReaderView:drawPageSurround()` had to be fixed to draw the margin under the footer so when tapping the footer off the area should be dran the background color.
`self.inverse_reading_order == nil and G_reader_settings:has("inverse_reading_order")` could easily be false, which would then incorrectly turn the setting off.
Fixes <https://github.com/koreader/koreader/issues/5346>.
This commit standardizes the various todos around the code a bit in a manner recognized by LDoc.
Besides drawing more attention by being displayed in the developer docs, they're also extractable with LDoc on the command line:
```sh
ldoc --tags todo,fixme *.lua
```
However, whether that particular usage offers any advantage over other search tools is questionable at best.
* and some random beautification
Close: #4997
This PR add support arrow key and mouse scroll wheel for next/previous page.
- Document in page mode:
PageDown, Arrow down, Arrow right - go to next page
PageUp, Arrow up, arrow left - go to prev page
Mouse scroll wheel down - go to next page
Mouse scroll wheel up - go to prev page
- Document in scroll mode:
PageDown, Arrow right - go to next page
PageUp, Arrow, arrow left - go to prev page
Arrow down - scroll document down
Arrow up - scroll document up
Mouse scroll wheel down - scroll document down
Mouse scroll wheel up - scroll document up
When multiswipes are enabled, this fixes the long-standing complaint that swiping to open the menu could unintentionally trigger some light panning. With the introduction of multiswipes, this problem has become more noticeable.
* 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 ;).
Make this existing setting tunable with a menu item.
Also make the Page overlap and Highlight menus use a
checkbox, and their items grayed out when disabled.
New zoom configuration available among the others
Allows to easily navigate in two-column documents
In order to work properly, **scroll mode must be deactivated**
The best zoom is obtained with proper cropping around the two columns (should be the default one for content-width)
Fixes#501
Touch zone decouples screen size from gesture event registration.
The win here is each individual widget does not need to update
gesture range on screen rotate/resize anymore.
Another advantage is we now have a centralized ordered array to handle
all registered touch event listeners, makes it much easier to resolve
gesture range conflicts between multiple widgets.
This patch also includes the following changes:
* migrate readerpaging to use readerui's touch zone
* migrate readerfooter to use readerui's touch zone
* move inverse read direction setting to touch menu's setting tab
* moved kobolight widget from readerview into readerui
* various dead code cleanups and comments
this should implement feature request of zoom mode for multi-columns
page in #501
This PR depends on koreader/koreader-base#435
How to use?
1. Tap the top left corner of a PDF/Djvu page to get into the flipping
mode
2. Double-tap on text block will zoom in to that column
3. Double-tap on any area will zoom out to an overview of the page
4. repeat step 2 to focus to another page block
How does it work?
1. We first find the mask of text blocks in the page. (Pic 1)
2. Then we intersect page boxes with user tap to form a page block. (Pic 2)
3. Finally we zoom the page to the page block and center current view to
that block. (Pic 3)
A new feature 'read from right to left' is added, which is more fit for
Traditional Chinese and Japanese books. Once the feature is enabled:
1. The gesture region of TapForward and area will be flipped
horizonally;
2. The action for swiping to west and to east will be exchanged.
