Detailed Description
The TouchPoint type contains information about a touch point, such as the current position, pressure, and area.
Property Documentation
These properties hold additional information about the current state of the touch point.
pressure
is a value in the range of 0.0 to 1.0.velocity
is a vector with magnitude reported in pixels per second.area
is a rectangle covering the area of the touch point, centered on the current position of the touch point.
Not all touch devices support velocity. If velocity is not supported, it will be reported as 0,0.
This property holds the point id of the touch point.
Each touch point within a MultiPointTouchArea will have a unique id.
These properties hold additional information about the current state of the touch point.
