* Add splitter in order to hide the details table.
* Add a toolbar to the Details Dialog window to allow for better image
comparisons: zoom in/out, swap pixmaps in place, best-fit-to-viewport.
Scrollbars and viewports are synchronized.
* Needed to ignore the scrollbar changes in the disabled
panel, sine a null pixmap would reset the bars to 0 and affect
the selected viewer.
* Keep view as same scale accross entries from the same group.
* Also fix scaled down pixmap when updating pixmap in the same group
* Fix ignoring mouse wheel event when max scale has been reached
* Fix toggle scrollbars when asking for normal size
* Work around flickering of scrollbars due to
GridLayout resizing on odd pixels by disabling
the scrollbars while BestFit is active
* Also setting minimum column width to work around
the issue above.
* Avoid updating scrollbar values twice by using a
simple boolean lock
Using a QWidget inside the QScrollArea mostly works
but we only move around the pixmap inside the QWidget,
not the QWidget itself, which doesn't update scrollbars.
Need a better implementation.
The controller singleton acts as a proxy to relay
signals from each widget to the other
It should help encapsulating things better if we need to
use a different class for image viewers in the future.
- Format all files with black
- Update tox.ini flake8 arguments to be compatible
- Add black to requirements-extra.txt
- Reduce ignored flake8 rules and fix a few violations
- Update qt/preferences_dialog.py to resize based on layout with fixed
sizing constraints
- Remove _setupUi from qt/se/preferences_dialog.py and just use the
parent class's function
- Remove unused imports from qt/se/preferences_dialog.py
Ticket #379 reports crashes on quit due to `willSavePrefs` being called
when result and details dialogs are already freed. I can't reproduce the
crash, but it's still a bad idea to rely on the timing of
`aboutToQuit()` to launch this process.
This commits uses a more predictable place to emit `willSavePrefs` and
I'm pretty sure it will fix the crash at #379.
