Detailed Description

Implementation of PlanarFigure modeling a cross with two orthogonal lines on a plane.

The cross consists of two two orthogonal lines, which are defined by four control points lying on a plane. The two control points of the first line are freely placable within the bounds of the underlying 2D geometry, while the two control points of the second line are ensured to meet the following constraints:

1.) The lines must be orthogonal to each other 2.) The second line must lie within the 2D area defined by the first line 3.) The two lines must intersect (at least with their boundaries)

When placing the second line interactively, a graphical helper polyline is provided to the user to indicate the position and orthogonal orientation of the line if it would be placed at the current mouse position.

When modifying one of the lines by interactively moving its control points, the respective other line is deleted and the user is prompted to draw it again.

The class provide a special mode for drawing single lines (SingleLineModeOn/Off); in this case, interaction stops after the first line has been placed.

The class provides the lengths of both lines via the "feature" interface, ordered by size.
