|Home GuiPack NumIO Class TNumIO2 Events OnGaugeChange|
|See also: TOnGaugeChangeEvent, Events of NumIO2|
The OnGaugeChange event is triggered when the user changes the gauge bar by mouse interaction. The parameter GaugeValue contains the current gauge value, the parameter Shift reflects the state of the Shift, Alt and Ctrl keys and the state of the mouse buttons.
Please note that the OnGaugeChange event is different from the OnChange event. The OnGaugeChange event occurs during the interactive change of the gauge (i.e. whenever the mouse moves over the gauge bar with the left button down), while the OnChange event occurs after the left button has been released.
