Using Events From A Class - events

Question

I am trying to get a function to be called everytime an event occurs. In the KinectRegion class there is an event called HandPointerGrip: http://msdn.microsoft.com/en-us/library/microsoft.kinect.toolkit.controls.kinectregion.handpointergrip.aspx.
I see that it has declared the event and it seems to me that the event has already been set to be invoked(HandPointerEventArgs)? How do I attach a function to this event?
public Menu()
{
KinectRegion.HandPointerGripEvent+=Hand_Gripped; // why doesn't this work? :(
}
private void Hand_Gripped(object sender, HandPointerEvnetArgs e)
{
MessageBox.Show("I work!"); // I wish this would work
}
Been working hard on this problem and here is something I think will work. Afraid to test it. Learning a lot about routed events, delegates, and events.
namespace ...
{
public delegate void HandPointerEventHandler(object sender, HandPointerEventArgs e);
public partial class thePage : Page
{
public event HandPointerEventHandler HandGripped
{
add {this.AddHandler(KinectRegion.HandPointerGripEvent,value);}
remove {this.RemoveHandler(KinectRegion.HandPointerGripEvent,vlaue);}
}
public thePage()
{
InitializeComponent();
this.HandGripped += new HandPointerEventHandler(OnHandGripped);
}
protected virtual void OnHandGripped(object sender, HandPointerEventArgs e)
{
MessageBox.Show("hello"); //hopefully
}
}
}

Answer 1

The first block of code should work fine. My guess is that the HandPointerGripEvent is hooked up ok, it just never fires.
How are you setting up your KinectRegion?
Are you updating the interration library each frame?
Perhaps this helps?

Answer 2

KinectRegion.AddHandPointerGripHandler(this.Button1, this.Button1_Click);
Here Button1 is:
< k:KinectTileButton x:Name="Button1" Height="150" Width="150" Content="Click"/ >
The namespaces:
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:k="http://schemas.microsoft.com/kinect/2013"
Button1_Click is the method itself, for example:
private void Button1_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("YOU GOT ME !!!");
}
If you want to add a grip handler for another interface object, you just do:
KinectRegion.AddHandPointerGripHandler(< object name >, < method name >);
And s.o.
