示例1: OnMouseDown
// Respond to the mouse button down event by setting up a hit test results callback.
private void OnMouseDown(object sender, MouseButtonEventArgs e)
{
// Retrieve the coordinate of the mouse position.
Point pt = e.GetPosition((UIElement)sender);
// Expand the hit test area by creating a geometry centered on the hit test point.
EllipseGeometry expandedHitTestArea = new EllipseGeometry(pt, 10.0, 10.0);
// Clear the contents of the list used for hit test results.
hitResultsList.Clear();
// Set up a callback to receive the hit test result enumeration.
VisualTreeHelper.HitTest(myControl, null,
new HitTestResultCallback(MyHitTestResultCallback),
new GeometryHitTestParameters(expandedHitTestArea));
// Perform actions on the hit test results list.
if (hitResultsList.Count > 0)
{
ProcessHitTestResultsList();
}
