This commit adds keyboard navigation to entry lists.
Selection of items can be done through keyboard (shift+up/down), mouse
(left, left+shift, left+ctrl) or touch (long press).
When items are selected, contextual actions will show up on
the page (useful for touch screens), or, alternatively, a context menu
with the same actions can be opened through right mouse click (useful
for desktop).
If a single entry is selected, then only the relevant actions will be
shown (e.g. only "Mark as Played" if the entry has not been played yet).
Additionally, (database) transactions for the actions have been
optimized. This was necessary to make sure that actions on large
selections of entries finish within an acceptable time. E.g. actions on
a list of 1000 items should finish within a few seconds (on all but
underpowered hardware).
BUG: 441764
The "New Episodes" tab is to be replaced by a filter view button and
dialog to be able to filter several episode statuses. I.e. new,
played / not played, etc.
For now this only works with NetworkManager. The related settings are
greyed out on systems not using NetworkManager.
Some details of the implementation:
- Implement settings in the settings menu to enable/disable feed
updates, episode downloads and/ or image downloads on metered
connections. If the option(s) is disabled, an overlay dialog is shown
with options to "not allow", "allow once", or "allow always".
- If the network is down, no attempt is made to download images and the
fallback image will be used until the network is up again.
This also solves an issue where the application hangs when the network
is down and feed images have not been cached yet.
- Next to this, part of the cachedImage implementation in Entry and Feed
has been refactored to re-use code as part of the image() method in
Fetcher.
- In case something unexpected happens, an error will be logged.
