* On Windows and MacOS, no idea how themes work so only allow Linux to use their theme icons
* Internal icons are used by default on non-Linux platforms
* When clicking the "Restore Default" in the preferences dialog, only affect the preferences displayed in the current tab. The hidden tab should not be affected by this button.
* Also limit viewing features such as zoom levels when files have different dimensions
* GraphicsViewImageViewer is still a bit buggy: the scrollbars are toggled on when the pixmap is null in the reference viewer (we do not use that class right anyway)
* If the dialog window shouldn't have a titlebar during construction, update accordingly only when showing to fix Windows displaying a window without titlebar on first show
* Only save geometry if the window is floating. Otherwise geometry while docked is saved whih gives weird results on subsequent starts, since it may be floating by default anyway (at least on Linux where titlebar being disabled is allowed while floating)
* Vertical title bar doesn't seem to work on Windows, add note in preferences dialog
* Windows users cannot move a window which has no native decorations. Toggling a dock widget's titlebar off also removes native decorations on a floating window. Until we implement a replacement titlebar by overriding paintEvents, simply force the floating window to go back to docked state after we toggled the titlebar off.
* Jason Cho gave his express permission to use the icon (it was made 10 years ago and he doesn't have the source files anymore)
* Used waifu2x to upscale the icon
* Used GIMP to draw dark outline around the icon
* Source files are included
* Use custom icons on platforms which do not provide theme
* Old zoom icons credits to "schollidesign" from icon pack Office and Entertainment (GPL licence).
* Exchange icon credit to Jason Cho (Unknown license).
* Use hack to resize viewers on first show() as well
* For some reason the table's height is a few pixel longer on Windows so we work around the issue by adding a small offset to the maximum height hint.
* No idea about MacOS yet but this might need the same treatment.
* Fix ME and SE versions of details dialog not displaying their content properly after change to QDockWidget
* Add option to toggle titlebar and orientation of titlebar in preferences dialog
* Fix setting layout on PE details dialog window while layout already set, by removing the self (parent) reference in constructing the QSplitter
* 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
