WhatsAt(Point point)
Finds features presented at the specified window position.Syntax
public PresentationObjectCollection WhatsAt (
Point point
)Parameters
The window position.
Return Value
Remarks
This method finds what has been presented inside a small rectangle around the specified pixel position. The size of the rectangle is 4 by 4 pixels.
The method returns a list of PresentationObject instances, for all presentations that overlap the rectangle, and that originate from selectable layers (see Layer.Selectable). The object that is drawn last (on top) is first in the list in 2D. In 3D, the closest object is first. Presentation objects created by selection visualizers sorted before all other presentation objects. The coordinates of the presentation objects are always in the coordinate reference system of the view.
WhatsAt(System.Int32 x, System.Int32 y)
Finds features presented at the specified window position.Syntax
public PresentationObjectCollection WhatsAt (
System.Int32 x,
System.Int32 y
)Parameters
The x-coordinate of the window position.
The y-coordinate of the window position.
