As we rely on the thumbnails cache, the images are already downscaled at
a small resolution. So there is no more need to force a max resolution
on the Qml Image.
If a project has already been opened before the "Import Images" dialog
is opened for the first time, and if the opened project has imported
images, use the location of these images' folder as the base folder for
the "Import Images" dialog.
If the opened project has no imported images, the base folder will remain
identical to the other dialogs' until images are imported.
The output of "cameraInit.attribute("sensorDatabase").value" is the
unresolved ${ALICEVISION_SENSOR_DB} environment variable.
To get the path, the variable needs to be evaluated.
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.
This commit ensures that any change in the ImageGallery's GridView
selection is correctly reflected in the Viewer2D. In particular:
- When a new project file is opened, the first image in the gallery
is now displayed in the 2D viewer, after a correct auto-fit has been
applied
- When an image in the gallery is removed, the adjacent image that
becomes selected is automatically displayed in the 2D viewer
* Width of columns is now provided by a column width provider
* Text inputs now cover all the column width
* Text inputs now are right aligned for easier reading/comparing
