the old code was allowing the main thread to read .port before it had
been updated, and was binding to sockets that were already in use on
Windows. instead, we use a system-assigned free port and block the main
thread until it's been allocated
- use a non-daemonized python thread
- shut the server down on exit, including from profile manager
- use a timeout on requests, or the connection that webengine holds open
will block the thread and prevent it from exiting when anki closes
- js code that was previously bundled in .py files is now in the
web folder
- add helpers to create links to bundled files, and update
stdHtml() to accept a list of javascript files to include
instead of text
- render MathJax in card layout and preview screens - these should be
updated in the future to update the document dynamically like the
reviewer does
- start media server earlier so it can be used to serve content for
the toolbar, etc
- work around a bug in WebEngine on Windows that could cause the
media server to hang
we can't use an event filter on the top level webview, because it
ignores the return value of the filter and leads to Anki thinking
keys have been pressed twice
and if we use an event filter on the focusProxy(), the
keypress/release events are sent even when a text field is currently
focused, leading to shortcuts being triggered when typing in the answer
to solve this, we move away from handling the key press events
directly, and instead install shortcuts for the events we want to
trigger. in addition to the global shortcuts, each state can install
its own shortcuts, which we remove when transitioning to a new state
also remove the unused canFocus argument to ankiwebview, and accept a parent
argument as required by the code in forms/
- key presses while a webview is focused no longer make it to the
main window's keyPressEvent() routine, so AnkiWebView now uses its
event filter to pass the key events to the main window
- move the shared key handling out of keyPressEvent into
globalKeyHandler()
- make sure all key handling routines return true or false to
indicate if an event was handled or not
- remove focus when esc hit in the main window, to retain old
behaviour of allowing esc to clear focus from the type answer box
onClose() was calling closeAllWindows(), which sends a close signal
to dialogs without force=True, causing them to fire an asynchronous
save event that calls back after the collection has been closed
instead we just rely on the fact that unloadCollection() closes all
collection windows
we do the backup compression/writing in a separate thread so it
doesn't slow down profile switching/syncing, and remove the option
to write uncompressed backups
the strip html option is no longer used, so remove it from preferences
- a few issues to work out still, and editor changes not done yet
- for communication between webengine and python code, we set window
.location to 'http://anki/<something>' - the leading http is
necessary for qt to call the link handler, which was introduced
in qt5.5
- the designer files now use a promoted qobject to create instances
of AnkiWebView
- we use the css zoom property to alter webengine font size based on
system dpi
- prefs and addons folder stored in new location (at least for now)
the canFocus/canCopy separate variables was silly, as we ended up
with text that could be copied from the context menu but not with
a shortcut key. also we default to allowing focus now, since that's
the more sensible default. fixes copy issues with card info dialog and
some addons
- advise user to create new profile, which prevents restores from
backup overwriting old backups
- don't rename the collection file, as it's no longer necessary,
and it fixes a windows bug where the main window would be left
open due to a failure to rename the locked collection file
