SnapPoint Method (GoView)

In This Topic

Find the nearest grid point to a given point when MoveSelection or CopySelection need to snap object locations to a grid.

Syntax

public virtual PointF SnapPoint( 
   PointF p,
   GoObject obj
)

Parameters

p: A PointF in document coordinates.
obj: the GoObject being moved or resized

Return Value

A PointF grid point in document coordinates, or else the value of if the point is not in or near any grid.

Remarks

This method looks at all top-level IGoDragSnapper objects, from front to back, in all layers that are part of this view, to see which one has the grid point closest to the given point . This calls IGoDragSnapper.IGoDragSnapper.CanSnapPoint to ask whether a grid object can participate in this calculation. If a grid's IGoDragSnapper.SnapOpaque property is true, it stops the search for any additional IGoDragSnapper objects that are underneath it.
