Detailed Description
Curve represented by a number of vertexes in a List.Use this for time running curves, since vertexes can be added and removed at both sides quickly.

modify point at index to x,y
Set the coordinates of the point at index to x,y.
- Parameters:
-
index the index of the point to change x new x for the point y new y for the point afterinversion if true the input x,y or first inverted with the local matrix of the object. The inverted values are used to set the point.
- Remarks:
- afterinversion = true should be used if you have x,y relative to the polygon object, while afterinversion = false should be used when x,y are relative to the point in the polygon.

only used for editable objects and under control of a editing tool.
If object is editable this function is used to initialize the object for editing. In general this means adding editing handles to the child list. In the event handling of the object those handles are hit and moved, the object itself is changed accordingly.
- Returns:
- true is this object can be edited and is initialized for that.
- Todo:
- edit of bbox ( children or not included )

| void a2dVertexListCurve::OnCanvasObjectMouseEvent | ( | a2dCanvasObjectMouseEvent & | event | ) | [protected] |
default handler for mouse events, sent to the object from the a2dCanvasView.
Mouse events are sent to the object when the mouse pointer is hiting the object. The default is used when the object is in edit mode. Else it will detect if the special object tip property named __OBJECTTIP__ is available, and switch it on or off when the mouse eneter or leaves the object.

Update derived Object specific things ( mainly boundingbox).
Calculates the boundingbox of the object (exclusif base class child objects but with other nested objects).
- Parameters:
-
mode way to update the objects childbox size of children boundingbox clipbox clip to this propbox size of properties boundingbox
- Remarks:
- in a derived class this function can also be used to update object specific cache data.
force may or may not have direct influence on the object itself, if this function is called directly for some reason (e.g from derived objects), you must invalidate the boudingbox yourself. GetDrawerBox()->SetValid( false );
Reimplemented from a2dCurveObject.
render derived object
if the object has sub objects (apart from the childobject which are handled here), those subobject most rendered by iterating on layer when needed/wanted, simular to child objects. We do not iterate here, since that is only needed if indeed there or subobjects. This will be know in a "wxDerivedCanvasObject DoRender".
SO parent objects that call this function, must:
- 1- clip object against area to redraw.
- 2- iterate on layers when needed.

| bool a2dVertexListCurve::DoIsHitWorld | ( | a2dIterC & | ic, | |
| a2dHitEvent & | hitEvent | |||
| ) | [protected, virtual] |
Does hit test on the object (exclusif child objects).
DoIsHitWorld() should return the way the object is hit by filling a2dHitEvent::m_how with the correct info.
- Parameters:
-
ic iterative context ( e.g. current transform WITH the local transform applied ) hitEvent stores hit information
- Returns:
- true if hit
