方法
FindElementAt``1(Point, Func<Visual, T>, Predicate<T>)
Search the parts in this layer that are at a given point that meet a given predicate, and return the first element that matches.
- 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 to be considered by the predicate . Typically the function will find the ancestor Part or Node.
- pred
- This is a predicate that is given an element of type ; if the predicate returns true, this method returns that element.
返回值: an element of type
FindElementsAt``1(Point, Func<Visual, T>, Predicate<T>)
Search the parts in this layer that are at a given point that meet a given predicate, and return a collection of elements that match.
- 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 to be considered by the predicate . Typically the function will find the ancestor Part or Node.
- pred
- This is a predicate that is given an element of type ; if the predicate returns true, this method includes that element in its results.
返回值: a collection of elements of type
OnVisualParentChanged(DependencyObject)
Every Layer's parent must be a DiagramPanel, if it has any parent.
- oldParent
