FindElementsAt<T> Method

Search all parts that are at a given point that meet a given predicate, and return a collection of elements that match.

Syntax

public IEnumerable<T> FindElementsAt<T>( 
   Point p,
   Func<Visual,T> navig,
   Predicate<T> pred,
   SearchLayers layers
)
where T: Visual

p: a Point in model coordinates
navig: This is a function that is given an element at the given point and returns an element of type T to be considered by the predicate pred. Typically the function will find the ancestor Part or Node.
pred: This is a predicate that is given an element of type T; if the predicate returns true, this method includes that element in its results. If this predicate argument is null, no filtering of elements is done -- all are included.
layers: The kinds of Layers to search in. For example, if you are looking for Nodes, using the value SearchLayers.Nodes, this will speed up the search by ignoring layers containing Links.

a perhaps empty collection of elements of type
