public MedicalViewerAlpha( int alpha, int sensitivity, bool circularMouseMove, Cursor cursor )

'Declaration Public Function New( _ ByVal alpha As Integer, _ ByVal sensitivity As Integer, _ ByVal circularMouseMove As Boolean, _ ByVal cursor As Cursor _ )

'Usage Dim alpha As Integer Dim sensitivity As Integer Dim circularMouseMove As Boolean Dim cursor As Cursor Dim instance As New MedicalViewerAlpha(alpha, sensitivity, circularMouseMove, cursor)

public: MedicalViewerAlpha( int alpha, int sensitivity, bool circularMouseMove, Cursor^ cursor )

Parameters

alpha: The alpha factor.
sensitivity: An integer value that represents the mouse sensitivity, in percent. Possible values are 1 - 100. Default is 100. A value of 100 indicates that the amount of change in the action is equal to the amount of movement of the mouse. For example, if the mouse is moved 1 pixel, the action changes by 1 unit. A value of 50 indicates that the amount of change in the action is 50 percent of the amount of mouse movement. For example, if the mouse is moved 2 pixels, the action only changes by one unit.
circularMouseMove: true to make the mouse reset when it reaches the side of the container (when the mouse resets, if it is dragged to one side of the container, it will disappear from that side and reappear on the opposite side of the container); otherwise, false.
cursor: Default cursor for the action.
