title: Track "commands" send to WPF window by touchpad (Bamboo)
body: <p>I just bought a touchpad wich allows drawing and using multitouch. The api is not supported fully by windows 7, so I have to rely on the build in config dialog.</p>
  
  <p>The basic features are working, so if I draw something in my WPF tool, and use both fingers to do a right click, I can e.g. change the color. What I want to do now is assign other functions to special features in WPF.</p>
  
  <p>Does anybody know how to find out in what way the pad communicates with the app? It works e.g. in Firefox to scroll, like it should (shown on this photo). But I do not know how to hookup the scroll event, I tried a Scrollviewer (which ignores my scroll attempts) and I also hooked up an event with the keypressed, but it does not fire (I assume the pad does not "press a key" but somehow sends the "scroll" command direclty. How can I catch that command in WPF?</p>
  
  <p>Thanks a lot,
  Chris</p>
  
  <p>[EDIT] I got the scroll to work, but only up and down, not left and right. It was just a stupid "listbox in scrollviewer" mistake. But still not sure about commands like ZOOM in (which is working even in paint).. Which API contains such things?</p>
  
  <p>[EDIT2] Funny, the zoom works in Firefox, the horizontal scrolling does not. But, in paint, the horizontal scrolling works... </p>
  
  <p>[EDIT 3] Just asked in the wacom forum, lets see about vendor support reaction time...

  <p>Here is a picture of the config surface to get the idea what I am talking about: (Bamboo settings, I try to catch these commands in WPF)</p>
