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");
    }
}
