for default factory methods.
Objects to be painted or manipulated are typically specified in model coordinates. These coordinates
are transformed to world coordinates and AWT view coordinates, e.g for painting or picking.
Therefore, the ILcdGXYPen
saves you a lot of work and helps you to write code which
is easier to understand and maintain.
An ILcdGXYPen
maintains a current position which is used by several methods.
It also provides a convenient way to transform between model, world and AWT coordinates.
Related methods are:
An ILcdGXYPen
stores an internal path which can be accumulated and painted.
The path is accumulated by appending lines, point lists, or arcs. Subsequently, it can
then be painted as a polyline, a polygon, or a filled polygon. Related methods are:
emptyAccumulated
accumulateLineTo
accumulatePointList
accumulateArc
drawAccumulatedPolyline
drawAccumulatedPolygon
fillAccumulatedPolygon
Alternatively, an ILcdGXYPen
allows to construct an external AWT path which the user
can modify, transform, or paint as required. Related methods are:
Similarly, lines, point lists, or arcs can be appended to an external general path which the user can modify, transform or paint as required. Related methods are:
An ILcdGXYPen
also provides a set of methods to paint elementary shapes such
as lines and arcs. Related methods are:
Furthermore, information can be obtained about the geometry of elementary shapes, such as distances and bounding boxes in AWT coordinates. Related methods are:
An ILcdGXYPen
also provides assistance with picking objects. Related methods are:
Finally, an ILcdGXYPen
allows the user to specify and paint hot points. Related methods are:
