Detailed Description

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. We derive from mpFunction to have symbol and continuity properties

Member Function Documentation

◆ DoPlot()

void mpMovableObject::DoPlot ( wxDC &  dc,
mpWindow w 
)
protectedvirtual

Pure virtual method to plot the layer.

Must be overridden and implemented by derived classes.

Implements MathPlot::mpLayer.

◆ HasBBox()

virtual bool MathPlot::mpMovableObject::HasBBox ( )
inlinevirtual

Check whether this layer has a bounding box.

The default implementation returns TRUE. Override and return FALSE if your mpLayer implementation should be ignored by the calculation of the global bounding box for all layers in a mpWindow.

Return values
TRUEHas bounding box
FALSEHas not bounding box

Reimplemented from MathPlot::mpLayer.

◆ ShapeUpdated()

void mpMovableObject::ShapeUpdated ( )
protected

Must be called by the descendent class after updating the shape (m_shape_xs/ys), or when the transformation changes.

This method updates the buffers m_trans_shape_xs/ys, and the precomputed bounding box.
