IOPComponent

public IOPComponent()

Method Detail

add

public void add(Glyphish glyphs)

remove

public void remove(Glyphish glyphs)

setGraph

public void setGraph(IOPGraph graph)

add

public void add(Glyphish glyphs,
                AffineTransform position)

isGlyphishVisible

public boolean isGlyphishVisible(Glyphish g)

Test whether given glyphish thing is currently visible. 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

setMouseAction

public void setMouseAction(int type,
                           Closure fun)

paintComponent

public void paintComponent(Graphics g)

Overrides:

paintComponent in class JComponent

checkSize

public void checkSize()

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

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

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).

Parameters:

factor - Zoom factor to apply

centerOn

public void centerOn(Glyphish g)

Deprecated. use centerOn(java.awt.geom.Rectangle2D) instead

centerOn

public AffineTransform centerOn(Rectangle2D rect)

Center component on given rectangle. Tries to move given rectangle to center but won't go across boundaries of the underleying canvas.

Parameters:

rect - Rectangle to center on

Returns:

AffineTransform describing the transformation done

zoomBound

public Rectangle2D zoomBound(Rectangle2D bound)
