This morning I decided to build a little WPF dialog window that would show the visual tree of some UI, and provide visual indicators over that UI when you select one of its elements.

Here’s the resulting dialog window in action:
Notice that a ContentPresenter is selected, which contains an image of a ninja. In the UI being analyzed, you’ll see that the ContentPresenter is decorated with a light green box:
The “Snooper” dialog window contains a TreeView that renders the visual tree of the other UI. That TreeView is declared as:
It is bound to a hierarchy of VisualElement objects. VisualElement is a class that I made to represent an element and its child elements. The important part of that class is seen below:
Notice that when a VisualElement is selected, it puts a SelectionAdorner into the adorner layer of its associated UIElement. SelectionAdorner is a class I made that just renders a rectangle around some element. It is seen below:
