# VObject Class
 
This is a base class for any v-object.
 
**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
  
```
<SerializableAttribute> _
Public MustInherit Class VObject _Implements IVObject, IControlPointsProvider, ISerializable, IDisposable
```
 
```csharp
[SerializableAttribute]
public abstract class VObject : IVObject, IControlPointsProvider, ISerializable, IDisposable
```
 
## Remarks
  
You can inherit from this class when you need to implement a custom v-object. To do it, you should implement:
 
- [HitTest(PointF, Single)](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_WinControls_VObject_HitTest_2_73e02abb.htm.md) method which checks whether a point with specific coordinates belongs to a v-object.
- [Draw(Rectangle, Graphics, ICoordinateMapper)](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_WinControls_VObject_Draw_3_d211987a.htm.md) method which draws the v-object on the surface of the control.
- [GetVObjectBounds()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_WinControls_VObject_GetVObjectBounds.htm.md) and [GetTransformedVObjectBounds()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_WinControls_VObject_GetTransformedVObjectBounds.htm.md) methods which return the bounds of the object.

Few of other minor members may be required to be implemented, but these one are the most essential.
