WhatsIn(Rectangle rectangle)
Finds features presented in the specified window rectangle.Syntax
public PresentationObjectCollection WhatsIn (
Rectangle rectangle
)Parameters
The window rectangle to check.
Return Value
Remarks
This method finds what has been presented inside the specified rectangle.
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.
The selection of objects using WhatsIn is implemented using local updates around the selection rectangle. Features that are outside of the selection area but have a visualization that intersects with the selection rectangle will in some cases not be detected by default (see OrdinaryLayer.PixelMarginLeft).
