title: Capture all Click or Touch events recursively in WPF
body: <p>am pretty new to WPF, but am looking to capture whenever anyone touches inside a window or any child controls.</p>
  
  <p>If I capture the click event for a Window, only the windows inner space capture the click. It's child controls do not.</p>
  
  <p>How do i recursively capture any click/touch event ANYWHERE on the screen in a full size window?</p>
  
  <p>many thanks in advance</p>
