Constructor Detail

LineFigure

public LineFigure()

Creates a new instance.

Method Detail

createHandles

public java.util.Collection<Handle> createHandles(int detailLevel)

Description copied from interface: Figure

Creates handles used to manipulate the figure.

Specified by:

createHandles in interface Figure

Overrides:

createHandles in class BezierFigure

Parameters:

detailLevel - The detail level of the handles. Usually this is 0 for bounding box handles and 1 for point handles. The value -1 is used by the SelectAreaTracker and the HandleTracker to highlight figures, over which the mouse pointer is hovering.

Returns:

a Collection of handles

canConnect

public boolean canConnect()

Description copied from class: BezierFigure

Checks if this figure can be connected. By default filled BezierFigures can be connected.

Specified by:

canConnect in interface Figure

Overrides:

canConnect in class BezierFigure

handleMouseClick

public boolean handleMouseClick(java.awt.geom.Point2D.Double p,
                                java.awt.event.MouseEvent evt,
                                DrawingView view)

Handles a mouse click.

Specified by:

handleMouseClick in interface Figure

Overrides:

handleMouseClick in class BezierFigure

Parameters:

p - The location of the mouse event.

evt - The mouse event.

view - The drawing view which is the source of the mouse event.

Returns:

Returns true, if the event was consumed.
