Class PolylineItem

java.lang.Object

edu.cnu.mdi.item.AItem

edu.cnu.mdi.item.PathBasedItem

edu.cnu.mdi.item.PolylineItem

All Implemented Interfaces:

IFeedbackProvider, IDrawable, EventListener

Direct Known Subclasses:

ConnectorItem

public class PolylineItem
extends PathBasedItem

An open, stroked-only polyline defined in world coordinates.

Unlike PolygonItem, the path is not closed back to its first point, and the fill color is forced to null so only the connecting segments are drawn. The geometry is stored as a world-coordinate Path2D; selection/reshape modifies vertices of that path.

Constructor Details

PolylineItem

public PolylineItem(Layer layer,
 Point2D.Double[] points)

Create a world polyline item

Parameters:

layer - the z layer this item is on.

points - the points of the polyline

PolylineItem

public PolylineItem(Layer layer,
 Point2D.Double[] points,
 Object... keyVals)

Create a world polyline item

Parameters:

layer - the z layer this item is on.

points - the points of the polyline

keyVals - optional key value pairs for styling the item. See AItem(Layer, Object...) for more details.

Method Details

drawItem

public void drawItem(Graphics2D g2,
 IContainer container)

Custom drawer for the item.

Overrides:

drawItem in class PathBasedItem

Parameters:

g2 - the graphics context.

container - the graphical container being rendered.

reshape

protected void reshape()

Reshape the polygon based on the modification. Not much we can do to a polygon except move the selected point. Keep in mind that if control or shift was pressed, the polygon will scale rather than coming here.

Overrides:

reshape in class PathBasedItem
