Methods

FinishSetup()

Perform final initialization tasks after the control hierarchy has been put into place.

Declaration
protected override void FinishSetup()
Overrides
Remarks

This method can be overridden to perform control- or device-specific setup work. The most common use case is for looking up child controls and storing them in local getters.

public class MyDevice : InputDevice
{
public ButtonControl button { get; private set; }
public AxisControl axis { get; private set; }

         protected override void OnFinishSetup()
         {
             // Cache controls in getters.
             button = GetChildControl("button");
             axis = GetChildControl("axis");
         }
     }</code></pre></example>
