Constructor Detail

GlyphPanel

public GlyphPanel()

Method Detail

getGlyphs

public GlyphList getGlyphs()

resetGlyphs

public void resetGlyphs()

setGlyphs

public void setGlyphs(GlyphList glyphs)

getGlyphSize

public java.awt.Dimension getGlyphSize()

checkSize

protected void checkSize()

isEmpty

public boolean isEmpty()

Test whether this glyph panel is empty.

Returns:

true if glyphs isn't set or doesn't contain any glyphs, 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()

Description copied from interface: Zoomer

Called to fit the subject of the zoom into the viewer.

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

getFrame

public javax.swing.JFrame getFrame()

isGlyphishVisible

public boolean isGlyphishVisible(Glyphish g)

Test whether given glyphish thing is currently visible in the parental viewport. Returns false if this gpanel is not embedded into a JViewport. Returns false if glyphish is not entirely inside the currently visible rectangle. If given glyph is null returns false.

Parameters:

g - Glyphish thing to test visibility of

Returns:

true, if glyph is completely visible, false otherwise

transformFromView

public java.awt.Point transformFromView(java.awt.Point p)
