* When right clicking on image viewers while they are docked, the context menu of the Results window showed up.
* This also enables capture of right click and middle click buttons to drag around images, which solves a conflict with some theme engines that enable left mouse button click to drag a window's position regardless of where the event happens, hence blocking the panning.
* Probably unnecessary to check which button is released.
* Sometimes, the splitter doesn't fully reach the table maximum height, and the scrollbar is still displayed on the right because a few pixels are still hidden.
* It seems the splitter handle counts towards the total height of the widget (the table), so we add it to the maximum height of the table
* The scrollbar disappears when we reach just above the actual table's height
* In some themes, the color picker widgets get stretched, while the color picker for the details dialog group doesn't.
This should keep them a bit more consistent across themes.
* Add testing feature to Exclusion dialog to allow users to test regexes against an arbitrary string.
* Fixed test suites.
* Improve comments and help dialog box.
* When recreating the Results window, the menubar had duplicate items added each time.
* Removing the underlying C++ object is apparently enough to fix the issue.
* SetParent(None) can still be used in case of floating windows
* The custom QStackWidget+QTabBar class did not manage the tabs properly because the indices in the stackwidget were not aligned with the ones in the tab bar.
* Properly disable exclude list action when it is the currently displayed widget.
* Merge action callbacks for triggering ignore list or exclude list to avoid repeating code and remove unused checks for tab visibility.
* Remove unused SetTabVisible() function.
* We need to set the Details Dialog's previous instance to None when recreating a new Results window
otherwise Qt crashes since we are probably dereferencing a dangling reference.
* Also fixes Results tab not showing up when selecting it from the View menu.
* Concatenating regexes into one Pattern might yield better performance under (un)certain conditions.
* Filenames are tested against regexes with no os.sep in them. This may or may not be what we want to do.
And alternative would be to test against the whole (absolute) path of each file, which would filter more agressively.
* In some cases, the function dump_IFD() in core/pe/exif.py assigns a string instead of an int as "values".
* This value is then used as _cached_orientation in core/pe/photo.py in _get_orientation().
* The method _plat_get_blocks() in qt/pe/photo.py was only expecting an integer for the orientation argument, so we work around the issue for now by ignoring the value if it's a string.
* Whenever the Result Window already existed and its tab was in second position, and if the ignore list tab was in 3rd position, asking to show the Result window through the View menu would add a new tab and push the Result tab to the third position (ignore list tab would then become 2nd position).
* Fix view menu Directories entry not switching to index "0" in custom tab bar.
* The close button on custom tabs cannot be hidden on MacOS for some reason.
* Prevent the directories tab from closing if the close button was clicked by mistake
* Use QGroupBox to keep items together on the display tab in the preference dialog just like for the other options.
* It is probably not be necessary to keep these as class members
* It seems that stretching the last section automatically is a bit inconvenient on MacOS as it will grow beyond the window border.
* Keep it as it was before for now until a better solution is devised.
* We use GroupBoxes to group items together and surround them in a frame
* Remove separator lines to avoid cluttering
* Adjust columns and their stretch factors for better alignment of buttons
* On Linux, even with 1 pixel size, the button is filled entirely with the color selected
* On MacOS, the color pixmap stays at 1 pixel so we hard code the size to 16x16
* Add Directories to the View menu.
* View menu items should be disabled properly depending on whether they point to the current page/tab.
* Keep "Load scan results" actions active while viewing pages other than the Directories tab.
* Restore the details dialog dock position if it was previously docked (i.e. not floating).
* Since the details_dialog instance was not deleted after closing by default, the previous instances were still saving their own geometry. We now delete them explicitely if we have to recreate a new instance to avoid the signal triggering the callback to save the geometry.
* Since restoreGeometry() and saveGeometry() are only called in our QDockWidget, it should be safe to modify the methods for the Preferences class (in qtlib).
