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
keyPressEvent/etc no longer work with qwebengineview, so we need to
install an event filter to catch things like ctrl+c. drag & drop
doesn't seem to be supported until 5.7
- 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
