type SegmentedControl struct {
// tabStop is the one segment Tab reaches; arrows move among the others.
}SegmentedControl paints a compact, neutral choice group. It retains no state: selection belongs to the application and every paint reads transient pointer and focus state from the canvas.
BeginSegmentedControl#func BeginSegmentedControl(canvas *ui.Canvas, theme ui.Theme, bounds ui.Rect, options []SegmentOption, selected ui.ID) SegmentedControlBeginSegmentedControl starts a segmented choice declaration. Each enabled, non-zero option ID becomes an independently focusable hit. The runtime's existing hit routing therefore activates the focused option with Enter or Space.
Disabled#func (control SegmentedControl) Disabled() SegmentedControlDisabled renders the complete control as inert.
Paint#func (control SegmentedControl) Paint() SegmentedControlResultPaint draws the track, one stable surface command per option, separators, labels, and hit regions. Stable option order keeps retained scene identities unchanged while hover, press, and selection only update command values. Each option's hit is a radio (checked when selected), disabled ones included.
