**Namespace:** [Aurigma.GraphicsMill.WinControls](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_WinControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.WinControls.VectorObjects (in Aurigma.GraphicsMill.WinControls.VectorObjects.dll)
 
## Syntax
  
```
Public MustOverride Function HitTest ( _point As Point, _coordinateMapper As ICoordinateMapper _
) As Boolean
```
 
```csharp
public abstract bool HitTest(Point point,ICoordinateMapper coordinateMapper
)
```
 
### Parameters
 
 - point
     - Type: [System.Drawing.Point](http://msdn2.microsoft.com/en-us/bk9hwzbw)
The point to check.

 - coordinateMapper
     - Type: [Aurigma.GraphicsMill.WinControls.ICoordinateMapper](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_ICoordinateMapper.htm.md)
An object that provides methods for mapping workspace coordinates to control ones.
 
### Return Value
 **true**, if the point is this control point; otherwise, **false**.
 
## Remarks
  
As the control point does not know anything about control scroll bars position and its zoom, it simply uses the specifed coordinateMapper to transform its own (workspace) coordinates to control coordinates.
