- Remove the "New" menu; the "Ctrl+N" shortcut remains valid to create
new default pipelines
- Move the "Save As Template" and "Import Project" actions into an
"Advanced" menu; their behaviour and shortcuts remain unchanged
- Add menu separators between the "Open" and "Save" functionalities,
the "Save" and "Import Images" functionalities, the "Import Images"
and "Advanced" functionalities, and the "Advanced" and "Quit"
functionalities.
The "cacheBuffer" property determines whether delegates are retained
outside the visible area of view. In the case of the ImageGallery,
it determines whether the images that are not currently visible in
the GridView (because we need to scroll up or down to be able to see
them) will remain in the cache or not. The default value is platform-
dependent (320 for Windows) and currently causes any image that is not
directly visible to be lost, even if it was previously loaded when it
appeared in the view: if we scroll up or down, we will necessarily need
to wait for the images to be loaded again.
10000 is an arbitrary value that seems to work correctly for most cases.
Some QML properties access exposed Python objects that may or may not
be null upon their access. When these objects are accessed while null,
QML issues "TypeError" warnings. These warnings have no functional
impact as QML correctly handles trying to access null objects, but can
spam the logs.
This commit aims at fixing all these warnings by checking that the
Python objects are not null before being accessed.
Regular expressions in regular strings generate deprecation warnings
with Python 3 ("invalid escape sequence \x"). To fix these warnings,
the regex must be contained within a raw string. For nodes that have
parameters whose description and/or value contain regex, the strings
are transformed into raw strings. In the case of descriptions, which are
generally written across several lines, regular strings are concatenated
with regular strings to preserve line returns (with "\n", which becomes
uneffective in raw strings).
In particular:
- In common/, remove the backport of weakref.WeakMethod
- In docs/ and ui/, use the standard FileNotFoundError class
- Use built-in open() instead of io.open(), and stop importing io
- In core/stats.py, use the standard implementation of xml.etree instead
of the C one
- "pyCompatibility.basestring" are replaced by standard Python3 "str"
- "Sequence" and "Iterable" from "collections" are now directly imported
with "collections.abc"
Change HColor default value from 5 to 10 as advised in the documentation
of OpenCV's non-local means denoising. Also update the description of the
H and HColor parameters so that they are easier to understand. The name
of the parameters is also updated to match with parameters from other
groups.
