Previously, when the bar was hidden, the height would be set to 0.
This meant that if the bar was empty upon reshow, it would not render
since the height was still 0, which made it seem there was a problem.
Now, the height is not reset, but the width is, to indicate upon reshow
that the layer surface needed reconfiguring.
As well as adding the hidden_state property to the bar config struct,
this commit handles barconfig_update events when the mode or
hidden_state changes, and uses a new function determine_bar_visibility
to hide or show the bar as required, using, respectively,
destroy_layer_surface, which is also newly added, and add_layer_surface,
which has been changed to allow dynamically adding the surface.
This distinguishes the binding mode from the distinct config mode, as
well as removing mode_pango_markup from the config struct where it
should not be present.
This was the source of numerous bugs, from hotplug events not being
received to segfaults because wl_display_roundtrip was making the
bar process unplug events while blocking in an iteration over all
outputs.
This now correctly handles an incoming json infinite array by shifting
most of the heavy listing to the json-c parser, as well as sending
multiple statuses at once. It also removes the struct
i3bar_protocol_state and moves its members into the status_line struct,
allowing the same buffer to be used for both protocols.
This prevents blocks from being destroyed before their hotspots are destroyed,
in case it is used for a pending click event that fires between the bar
receiving a new status, which destroys the block, and the bar rendering the new
status, which destroys the hotspot; this problem can be easily produced by
scrolling on a block that immediately causes a new status to be sent, with
multiple outputs
This does the following:
* Adds a baseline argument to get_text_size (the baseline is the
distance from the top of the texture to the baseline).
* Stores the baseline in the container when calculating the title
height.
* Takes the baseline into account when calculating the config's max font
height.
* When rendering, pads the textures according to the baseline so they
line up.
As well as ignoring scroll events on status elements when click_events
is enabled.
Previously, using the scroll wheel on a workspace button would switch to
that workspace instead of scrolling through them. Clicks and scrolling
on status elements would always be processed by swaybar, too. So in case
you were using scrolling as volume control on a status item, swaybar
would additionally scroll through your workspaces.
This starts up the event loop and wayland display and shims out the
basic top level rendering concepts. Also includes some changes to
incorporate pango into the 1.x codebase properly.
This commit implements the StatusNotifierItem protocol, and enables
swaybar to show tray icons. It also uses `xembedsniproxy` in order to
communicate with xembed applications.
The tray is completely optional, and can be disabled on compile time
with the `enable-tray` option. Or on runtime with the bar config option
`tray_output none`.
Overview of changes:
In swaybar very little is changed outside the tray subfolder except
that all events are now polled in `event_loop.c`, this creates no
functional difference.
Six bar configuration options were added, these are detailed in
sway-bar(5)
The tray subfolder is where all protocol implementation takes place and
is organised as follows:
tray/sni_watcher.c:
This file contains the StatusNotifierWatcher. It keeps track of
items and hosts and reports when they come or go.
tray/tray.c
This file contains the StatusNotifierHost. It keeps track of
sway's version of the items and represents the tray itself.
tray/sni.c
This file contains the StatusNotifierItem struct and all
communication with individual items.
tray/icon.c
This file implements the icon theme protocol. It allows for
finding icons by name, rather than by pixmap.
tray/dbus.c
This file allows for asynchronous DBus communication.
