Cache ALabel tooltip markup and provide it through query-tooltip instead of repeatedly setting GtkWidget's tooltip-markup property. This prevents frequently updating modules from restarting GTK's display-wide tooltip timer.
Keep the active tooltip updated directly so dynamic tooltip contents continue refreshing while the pointer remains stationary.
2190871a (perf(label): skip redundant markup updates) caches the last
label/tooltip markup as Glib::ustring and skips set_markup() when the
new markup compares equal. Glib::ustring::operator== goes through
g_utf8_collate(), and under the UTF-8 locale GTK sets at startup,
Unicode private-use codepoints carry no collation weight. All nerd-font
icons live in the PUA, so two labels that differ only in their icon
glyph collate as equal and the visual update is silently dropped.
idle_inhibitor is the visible victim (#5169): clicking toggles the
state class (highlight changes) but the {icon} glyph never switches
between the activated/deactivated icons, while plain-text icons like
"YES"/"NO" work. Any ALabel module whose consecutive updates differ
only by a PUA glyph is affected. The module only started routing
through this cache when db4941ef migrated it onto the shared
setLabelMarkup()/setTooltipMarkup() helpers, which is why it broke in
the latest batch of refactors.
Store the cache as raw UTF-8 bytes (std::string via ustring::raw())
and compare those instead, so the skip only triggers on byte-identical
markup. Reproduced and verified under a nested niri session: before the
fix RTMIN+n toggled the state class but left the sleep glyph unchanged;
after it the glyph flips as expected, and byte-identical updates are
still skipped.
Move resolveTooltipFormat() (and add resolveFormat()) from ALabel down into
AModule, and add a generic updateTooltip(Gtk::Widget&, ...) helper. This lets
modules that are not ALabel-derived reuse the shared tooltip logic instead of
re-implementing it. Migrate gamemode (the only non-ALabel module reading
tooltip-format) to updateTooltip(box_, ...). ALabel inherits the resolvers.
Migrate cpu, cpu_usage, cpu_frequency and memory to the generic
updateLabelAndTooltip/ForState helper so label and tooltip rendering go
through the dedup-aware setters and shared tooltip-format resolution.
Add store-accepting overloads of the helper to ALabel for modules that
build a dynamic fmt argument store (per-core cpu stats). cpu keeps its
tooltip-format-<state> selection via the state overload; the others keep
their existing tooltip-format-only behavior.
Modules duplicated the same boilerplate to format their label and tooltip
(read tooltip-format, fmt::format, set_tooltip_markup) across ~29 modules.
Add updateLabelAndTooltip(labelFormat, tooltipDefault, args...) and its
state-aware variant updateLabelAndTooltipForState(state, ...) to ALabel: they
build a single fmt arg store, render the label and the resolved tooltip format
(tooltip-format[-state] or default) through the dedup-aware setters, honoring
the tooltip toggle. resolveTooltipFormat() centralizes the format resolution.
Migrate temperature and disk as the first adopters.
- Declare event handler in ALabel virtual so the idle_inhibitor can
overriding them
- Handle the right click event in idle_inhibitor and call ALabel handler if needed
This patch adds 3 new configuration options applicable for
subclasses of ALabel. The options can be used to execute
user defined code in response to the 3 mouse events:
* on-click: The left mouse button click
* on-scroll-up
* on-scroll-down
This patch also modifies the behaviour of the format-alt toggle
such that when the on-click event is configured, format-alt is
toggled on any mouse click other than left click. When on-click
is not defined, any mouse button would toggle format-alt.
