Use IndexSet to allow direct access by Path and also allow
an arbitrary ordering that was not possible with Vec. Also
add monitoring of file changes in the directory.
Use a custom LpSlidingView instead of AdwCarousel because
Carousel was never designed for this job and suffered of
bugs. LpSlidingView does not support swiping gestures yet
since they currently don't work yet anyways #24.
Use a new algorithm to fill the LpSlidingView that is
stateless and covers all potential changes in the directory.
This not only fixes bugs but would also work with changed
sorting orders.
This also adds build time template XML validation since it
was useful for the refactoring #46.
Closes#9, #11, #30, #33, #42
glib-rs provides an API to get file collation keys that
can be used for comparison. This means we do not need to
use the function for this ourselves.
This commit gets rid of the manual binding for
`g_utf8_collate_key_by_filename ()` in favor of the glib-rs
API.
Give LpImage a native with that should feel nice.
When opening a new window with a new image the window size
is determined by LpImage's natural width.
The image size and EXIF data is loaded before the image such
that the window can be shown in the right dimension while
loading the actual image.
Implement a properties sidebar. In order to prevent
the UI from freezing, we use futures to load and cancel
loading file information. We also make use of
`gdk_pixbuf` and `svg_metadata` in order to get the file's
metadata before the file fully loads, meaning there's
little to no delay between changing files and seeing
the metadata for large images.
The properties widget uses expressions and
properties to avoid glue code for setting each label,
allowing us to have a clean separation between UI
and data.
Binary search is a fast method to sort for an item within
a sorted list. We have a sorted list, so we can take advantage
of binary search instead of having a linear traversal through
the list.
Because binary search requires a sorted list, we need to use
the same logic for sorting and searching. Here we factor out
the filename comparison logic into `util::compare_by_name()`.
In the future we may want to have a module for sorting algorithm
logic and checking what sorting algortihm Nautilus uses.
This commit adds directory navigation to Image Viewer.
Currently it only sorts images by name, instead of following
directory sorting like the mockups.
