Package topo :: Package tkgui :: Module editor :: Class EditorProjection

Class EditorProjection

Represents any topo CFProjection. It is a subclass of EditorEPConnection and fills in the methods that are not defined. Can be represented by a representation of a projection's receptive field or by a line with an arrow head in the middle; lateral projections are represented by a dotted ellipse around the center. Can determine if x,y coord is within the triangular receptive field or within an area around the arrow head. The same can be determined for a lateral projection ellipse.
