MouseWheelParameters.DeltaScale | deltaScale property

Applies to Windows and Windows Phone

Gets or sets a value that indicates the change in scale associated with input from the wheel button of a mouse.

Syntax


var deltaScale = mouseWheelParameters.deltaScale;
mouseWheelParameters.deltaScale = deltaScale;

Property value

Type: Number [JavaScript] | System.Single [.NET] | float32 [C++]

The relative change in scale, in degrees.

Remarks

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
