Constructor Detail

SwingWrapper

public SwingWrapper(javax.swing.JComponent c)

Construct a new swing wrapper instance to wrap the given component.

Method Detail

getBounds

public java.awt.geom.Rectangle2D getBounds()

Get the bounding box of this figure. This method overrides the inherited method to take account of the thickness of the stroke, if there is one.

Specified by:

getBounds in interface Figure

Overrides:

getBounds in class AbstractFigure

Returns:

the bounding box of this figure.

getComponent

public javax.swing.JComponent getComponent()

Return the component that this is wrapping.

getShape

public java.awt.Shape getShape()

Get the shape of this figure.

Specified by:

getShape in interface Figure

Specified by:

getShape in class AbstractFigure

Returns:

the outline shape of this figure

paint

public void paint(java.awt.Graphics2D g)

Ask the wrapped component to paint itself.

Specified by:

paint in interface VisibleComponent

Specified by:

paint in class AbstractFigure

Parameters:

g - The 2D graphics object that this object it to be painted upon.

setComponent

public void setComponent(javax.swing.JComponent c)

Replace the currently wrapped component with the given component and reshape/repaint the figure.

setParent

public void setParent(CanvasComponent fc)

Set the parent of this figure. This method overrides the inherited method to deal with the Swing component hierarchy.

Specified by:

setParent in interface Figure

Overrides:

setParent in class AbstractFigure

Parameters:

fc - The parent of the figure.

See Also:

Figure.getParent()

transform

public void transform(java.awt.geom.AffineTransform at)

Transform the figure with the supplied transform. For now this throws an UnsupportedOperationException because it is unclear how we want to deal with transformations that are not shape-preserving, such as shears and rotations.

Specified by:

transform in interface Figure

Specified by:

transform in class AbstractFigure

Parameters:

at - The transform to be used.

translate

public void translate(double x,
                      double y)

Translate the figure by the given distance.

Specified by:

translate in interface Figure

Overrides:

translate in class AbstractFigure

Parameters:

x - The x value to be moved.

y - The y value to be moved.
