For some reason, when e.g. visiting duckduckgo and then heise.de,
QtWebEngine suddenly gets a new QOpenGLWidget as focusProxy.
We install an extra eventFilter observing the ChildAdded event and
re-adding the MouseEventFilter when that happens.
Command completions for `:bind` and `:` will now show bindings for
aliases. The binding is only included if it is bound to that alias, not
if it is bound to the command the alias points to.
Consolidate the logic used to generate the command completion category
into one place. This is shared by CommandCompletionModel,
HelpCompletionModel, and BindCompletionModel.
Hidden commands are not shown in command completion as they typically
would not be run directly. However, a user might still might like to see
help for them if, for example, they are writing a script or creating a
binding.
Addresses #1707.
Wire up the config change event to update command completion on
changing aliases, so the new aliases will be included.
Fixes#1814.
Currently we do not have tests at a high enough level to test whether
signals are wired up correctly to update completions.
Completion.empty existed to fill a slot in the old Command.completions
interface if the first positional arg had no completions but the second
did, as is the case for the `bind` command. Now that
`Command.completions` is replaced by `Command.get_pos_arg_info`, this
is no longer needed.
Command completion types are now identified by ArgInfo, so just use
that directly and cut out the middle-man. This shouldn't change any
completion behavior.
Adds a test for get_pos_arg_info to test_cmdutils.
Modifies test_completer to test the use of get_pos_arg_info. Instead of
using FakeCommand, real Command objects are used, to validate that the
Completer works with the real Command interface. This also cleans out
some test cases that were testing things already covered by other cases.
This is a more rigorous test than filterAcceptsRow as it tests behavior
with multiple columns and different sort settings. In addition, it
tests intelligentLessThan which is not tested in the filterAcceptsRow
test (as lessThan is never called if there is only 1 item to filter).
With QtWebKit or QtWebEngine with Qt < 5.7, the functions end up in the
page's namespace. We can't easily avoid this, but at least we can name
them in a way which reduces conflicts.
