When natural scrolling is enabled, the behaviour of scrolling on pulseaudio
module is reversed, this commit reverses the direction of scroll variable
if "reverse-scrolling" is set to 1 in config file.
After this refactoring:
1. Timezones parses only once on start and the we refer to saved values. All time_zone.isString() checks gone to the constructor.
2. Single timezone case handling as case of multi timezoned logic.
3. Scroll event seems more clear now.
4. Tooltip template parses on start to check if there calendar placeholder or not. To do not calculate calendar_text() if not necessary.
Also fixed timezones behavior: now waybar starting with the first timezone in timezones list and falling back to timezone field only if timezones omit or has no elements.
`show_all` call from `Tray::update` attempts to walk the widget tree and
make every widget visible. Since we control individual tray item
visibility based on `Status` SNI property, we don't want that to happen.
Modify `Tray::update` to control the visibility of a whole tray module
only and ensure that the children of `Item` are still visible when
necessary.
This fixes issue #610 by reading bandwidth usage per-interface from
/proc/net/dev instead of globally via /proc/net/netstat. It supports the
same matching logic as elsewhere, so setting interface to '*' should
display the same sum-total bandwidth usage as the previous
implementation.
- Delete previous Layout before creating next one, and in destructor
- Use stack XKBContext instead of local new+delete
- Lock mutex in update() as it is called from a different thread than onEvent(res)
On the `Passive` value of `Status` tray items would be hidden unless
`show-passive-items` is set to true.
On the `NeedsAttention` value of `Status` tray items will have a
`.needs-attention` CSS class.
