labelWidget label; interactive widgets also use it for ID generation. A ## suffix can distinguish IDs without displaying the suffix.
v_radAngle stored in radians in Float32Array[0]; the widget displays degrees and writes radians back. Pass Float32Array storage, not a JS scalar; native access uses the supplied backing memory.
v_degrees_minLower/upper slider endpoint in degrees, although v_rad stores radians.
v_degrees_maxLower/upper slider endpoint in degrees, although v_rad stores radians.
formatNative printf-style numeric display format; match it to the value type. Null selects the native default where supported.
flagsImGuiSliderFlags options controlling this operation; combine compatible flag bits with |.
True if the widget changed the supplied value; false if it remained unchanged.
