Fixes#6489.
The issue arose in multitap scenarios, where the tip display state
became desynchronised with the actual display state as maintained in
the Android code.
The fix I applied was to reduce some of the state checks into the js
wrapper android-host.js. This is not ideal. The state machine for key
tip display is scattered across four functions in three files:
* visualKeyboard.ts: VisualKeyboard.highlightKey
* visualKeyboard.ts: VisualKeyboard.showKeyTip
* embedded/keytip.ts: KeyTip.show
* android-host.js: oskShowKeyPreview / oskClearKeyPreview
I have moved the actual re-creation check for the tip to the lowest
level functions -- those in android-host.js. But a more detailed look at
the state machine and a refactoring would certainly be worthwhile.
Fixes#6455.
This involved adding an extra hint to the data passed into the lexical
model layer, being the CasingForm that the current layer wants to use.
Given there are several entry points to the lexical model layer, this
meant a few places where we needed to check the current layer.
I refactored the very long function `InputProcessor.processKeyEvent` to
extract out the `buildAlternates` function. There should be no
functional changes to the `buildAlternates` code. But it makes
`processKeyEvent` significantly easier to read.
While this was done in code as a global override, probably following
Apple stylistic changes, it is better to leave this to the keyboard
developer to decide on.
Adjusts the dimensions to use pixel boundaries to prevent antialiasing
for some of the key preview and longpress popups, and adjusts horizontal
positioning of key preview to center more precisely, for iOS.
Fixes#5929.
Fixes#6381.
This fixes four separate issues with the longpress popups and key
previews:
1. The key preview was offset by a couple of pixels (unreported issue).
2. The background 'shim' did not cover the key caps, which caused them
to look startlingly white when the rest of the background greyed
down (#5929).
3. The popup menu was incorrectly wrapping to two rows due to sizing
model mismatches (#6381).
4. The popup menu would be realigned incorrectly for the in-app
keyboard, when moving it to keep it in the keyboard area (#5929).
Fixes#6364.
Removes `&layerChanged` and adds `&newLayer` and `&oldLayer` system
stores with the additional nuances around values as described in #6364.
When embedding the On Screen Keyboard into a page, the calculation for
the bounding rectangle only took into account the first offsetParent,
which meant it would get the offset incorrect when there were multiple
layers of offsetParents.
Once I changed to using getAbsoluteX / getAbsoluteY, this also corrects
for scroll with window.pageOffsetY, so we can eliminate that special
case for fixed positioning.
This was observable in the Web Developer test window, where interaction
with the bottom row of the keyboard in touch mode was not working
correctly, in 15.0.210-beta.
The Caps Lock change I made in the previous commit broke
desktop Caps Lock handling. The fix was a little more
convoluted. Turns out that _UpdateVKShift is also pretty
crufty. I simplified it, removing dead code.
Fixes#5964.
It seems that the test for subkey position was incorrect when the
document had been scrolled. Removing the test for `fixed` positioning
resolves the issue.
This fixes an issue that arises when loading the Keyman Developer Server
home page and there are registered keyboards, but no keyboards active.
The floating osk view would throw an exception because it would attempt
to set the title of the view from the active keyboard, which is `null`.
