Creation and lifecycle

Private jGauge1 As jGauge

jGauge1.Initialize(Me, "jGauge1")
jGauge1.AddToParent(Root, 20dip, 20dip, 360dip, 260dip, "", "%", 0xFF2C3144, 0xFFFFFFFF, 0xFF111827, 18, False, 20dip)

Working example

Dim Ranges As List
Ranges.Initialize
Ranges.Add(jGauge1.CreateRange(0, 40, 0xFF22C55E))
Ranges.Add(jGauge1.CreateRange(40, 75, 0xFFF59E0B))
Ranges.Add(jGauge1.CreateRange(75, 100, 0xFFEF4444))

jGauge1.SetMinAndMax(0, 100)
jGauge1.SetRanges(Ranges)
jGauge1.CurrentValue = 64
