This virtual class represents objects that can be moved to an arbitrary 2D location+rotation.
The current transformation is set through SetCoordinateBase. To ease the implementation of descendent classes, mpMovableObject will be in charge of Bounding Box computation and layer rendering, assuming that the object updates its shape in m_shape_xs & m_shape_ys.

Plot given view of layer to the given device context.
An implementation of this function has to transform layer coordinates to wxDC coordinates based on the view parameters retrievable from the mpWindow passed in w. Note that the public methods of mpWindow: x2p,y2p and p2x,p2y are already provided which transform layer coordinates to DC pixel coordinates, and user code should rely on them for portability and future changes to be applied transparently, instead of implementing the following formulas manually.
The passed device context dc has its coordinate origin set to the top-left corner of the visible area (the default). The coordinate orientation is as shown in the following picture:
(wxDC origin 0,0) x-------------> ascending X ----------------+ | | | | | V ascending Y | | | | | | | |+------------------------------------------+ <-- right-bottom corner of the mpWindow visible area.
Note that Y ascends in downward direction, whereas the usual vertical orientation for mathematical plots is vice versa. Thus Y-orientation will be swapped usually, when transforming between wxDC and mpLayer coordinates. This change of coordinates is taken into account in the methods p2x,p2y,x2p,y2p.
Rules for transformation between mpLayer and wxDC coordinates
dc | Device context to plot to. |
w | View to plot. The visible area can be retrieved from this object. |
