Gets or sets a value that indicates the change in scale associated with input from the wheel button of a mouse.
public:
property float32 DeltaScale {
float32 get ();
void set (float32 value);
}
Type: float32
The relative change in scale, in degrees.
The mouse wheel button has discrete, evenly spaced notches or distance thresholds (also called detents). When you rotate or tilt the wheel, a wheel message is sent as each detent is encountered.
DeltaScale maps a single notch (unitary rotation) of the wheel button to a scale multiplier or divider (for example, 1.1).
Rotating the wheel button forward or tilting it to the right results in a scale increase. Rotating backward or tilting to the left results in a scale decrease.c++**javascript
