setGraph

public void setGraph(IOPGraph g)

getGraphSize

public java.awt.Dimension getGraphSize()

checkSize

protected void checkSize()

isEmpty

public boolean isEmpty()

Test whether this graph panel is empty.

Returns:

true if graph isn't set or doesn't contain any nodes, false otherwise

addZoomListener

public void addZoomListener(ZoomListener zl)

Add given zoom listener to list of objects to be notified upon zoom change.

Parameters:

zl - ZoomListener to be notified upon zoom change

removeZoomListener

public void removeZoomListener(ZoomListener zl)

Remove given zoom listener from list of objects to be notified upon zoom change.

Parameters:

zl - ZoomListener to be removed

notifyZoomListeners

protected void notifyZoomListeners()

getZoomScale

public double getZoomScale()

Obtain current zoom scale in effect. Uses only x-portion of scaling in the current affine transformation as this should be equal to the y-portion of scaling.

Returns:

Current scaling factor in effect for x- and y-axis

getInverseZoom

protected java.awt.geom.AffineTransform getInverseZoom()

zoom

public void zoom(double factor)

Apply given factor to current zoom. A value smaller than 1.0 means zooming out (everything becomes smaller). A value greater than 1.0 means zooming in (everything becomes bigger).

Specified by:

zoom in interface Zoomer

Parameters:

factor - Zoom factor to apply

zoomToFit

public void zoomToFit(java.awt.Dimension size)

Zoom the size of the graph so that it fits into given dimension and its size is maximized. If given dimension is null does nothing.

Parameters:

size - Dimension, in which the zoomed graph must fit into

zoomToFit

public void zoomToFit()

Zoom the size of the graph so that it fits into its parents viewport.

Specified by:

zoomToFit in interface Zoomer

zoomToOriginal

public void zoomToOriginal()

Change the size of graph back to its original size.

Specified by:

zoomToOriginal in interface Zoomer

centerOn

public void centerOn(java.awt.Rectangle r)

Center component on given rectangle. Rectangle is specified in coordinates of underlying graph. Tries to move given rectangle to center but won't go across boundaries of the underleying canvas. Does nothing if given rectangle is null.

Parameters:

r - Rectangle to center on

highlight

public void highlight(GraphItem item)

Select given graph item (node or edge) by highlighting it. Accepts NULL as item; in this case won't do anything other than remembering NULL as the last item selected.

Parameters:

item - Node or edge to select in graph; may be NULL if nothing to be selected

displayMenu

public void displayMenu(IOPNode node)

Display context menu for given node.

Parameters:

node - Node for which to display context menu
