Expand description

Drag value widget for editing time values for both sequence and temporal timelines.

Compute and store various information about the time range related to how the UI should behave.

Fields§

§range: RangeInclusive<i64>

Allowed range for value.

§base_time: Option<i64>

For ranges with large offsets (e.g. log_time), this is a rounded time just before the first logged data, which can be used as offset in the UI.

§unit_factor: i64

For temporal timelines, this is a nice unit factor to use.

§unit_symbol: &'static str

For temporal timelines, this is the unit symbol to display.

§abs_range: RangeInclusive<i64>

This is a nice range of absolute times to use when editing an absolute time. The boundaries are extended to the nearest rounded unit to minimize glitches.

§rel_range: RangeInclusive<i64>

This is a nice range of relative times to use when editing an absolute time. The boundaries are extended to the nearest rounded unit to minimize glitches.

Implementations§

source§

impl TimeDragValue

source

pub fn from_time_histogram(times: &TimeHistogram) -> Self

source

pub fn from_time_range(range: RangeInclusive<i64>) -> Self

source

pub fn min_time(&self) -> TimeInt

Return the minimum time set for this drag value.

source

pub fn max_time(&self) -> TimeInt

Return the maximum time set for this drag value.

source

pub fn sequence_drag_value_ui( &self, ui: &mut Ui, value: &mut TimeInt, absolute: bool, low_bound_override: Option<TimeInt> ) -> Response

Show a sequence drag value widget.

source

pub fn temporal_drag_value_ui( &self, ui: &mut Ui, value: &mut TimeInt, absolute: bool, low_bound_override: Option<TimeInt>, time_zone_for_timestamps: TimeZone ) -> (Response, Option<Response>)

Show a temporal drag value widget.

Feature rich:

  • scale to the proper units
  • display the base time if any
  • etc.

Returns a tuple of the [egui::DragValue]’s [egui::Response], and the base time label’s [egui::Response], if any.
