Added spaces to comments, use python naming conventions, remove
_load_progress_fake as unnecessary, rename _on_load_*_fake to
_on_load_*_workaround (for less confusion), and use qtutils rather than
QT_VERSION_STR
This uses the much more reliable `loadProgress(100)` in place of
`loadFinished(true)` for WebEngine, with `loadProgressFake` and
`loadFinishedFake` used instead of the 'official' variants.
Update the description to mention the number of columns and change the
default to ["white", "white", "white"] to make it more obvious that
multiple colors can be specified. This also satisfies the config test
that expects the default value for ListOrValue types to be a list.
One other test had to be tweaked to use a config option that is still
just a QtColor rather than a ListOrValue.
While it is possible to provide just two colors, it is "undefined
behavior". It will use the first color as the third color, but that is
an artifact of the implementation and therefore not documented (though
also not an error, as it is harmless).
When QtWebEngine shuts down, it calls pending callbacks, which means we access
an invalid 'settings' object when that happens. The stack would look something
like this:
0 QtWebEngineCore::WebEngineSettings::setAttribute(QtWebEngineCore::WebEngineSettings::Attribute, bool)
12 QtWebEngineCore::CallbackDirectory::invokeEmptyInternal<QVariant const&>(QtWebEnginePrivate::QWebEngineCallbackPrivateBase<QVariant const&>*)
14 QtWebEngineCore::CallbackDirectory::~CallbackDirectory()
19 QWebEnginePage::~QWebEnginePage()
If we instead get the settings from the view freshly, we get a RuntimeError from
PyQt telling us that it's dead. Not sure why it doesn't know about settings
being dead...
With that, we'd get a RuntimeError, which we can simply ignore as it doesn't
matter anyways if the tab is gone.
Fixes#3399
