slider
element slider: node
A slider: slider { value: <-> audio.sink.volume }. Dragged, it
writes values in its range: slider { value: <-> percent; range: 0, 100 }. Laid out taller than wide (width: 24; height: 160), it runs
upward: its value grows from the bottom (its written width and
height decide, else its laid-out box; one growing from a written 0,
width: 0; grow: 1, runs along that axis; a drag keeps the way it
began).
It takes no children.
Also every prop and event of node.
| Prop | Type | |
|---|---|---|
value | <-> float | Its value, in range (0 to 1 when unset), bound two-way; a value outside it is drawn at its nearer end. |
range | float, float | The values its ends stand for: range: 0, 100 (0 to 1 when unset). A drag writes values between them. |
track | paint | The paint of the unfilled track. |
step | float | A drag moves in whole steps of this, in range's units from its low end (range: 0, 100; step: 5), and writes the decimal they spell (step: 0.1 writes 0.9, never 0.90000004); unset, it moves freely. |
