public class BoundaryPanel
extends Plane
A class which shows the fundamental domain corresponding to the current trace value and display parameters, on a portion of the boundary of hyperbolic space.

Author:
Jonathan A. Poritz

Variable Index

o boundarypanellabel
A reference to the label in outputpanel declaring the portion of the boundary of hyperbolic space which is currently visible.
o calcmaxpow
The maxpow calculated for a Ford domain with the current trace -- not necessarily valid for a Dirichlet domain with the same trace, but used nonetheless.
o chosenmaxpow
The overriding maxpow chosen by the user if so desired taken from maxpowchoice.
o CX
The abstract x-coordinate of the left side of the boundary plane display.
o CY
The abstract y-coordinate of the upper edge of the boundary plane display.
o diskorcircle
A reference to the choice in outputpanel of displaying disks, circles or circle with labeling indices.
o dist
The currently selected axis distance.
o fordordirichlet
A reference to the choice in outputpanel of computing Ford or Dirichlet domains.
o nc
An array of BoundaryCircles with negative indices.
o pc
An array of BoundaryCircles with positive indices.
o prev
The location of a mousedown in this plane, to compute the extent of a drag that may occur; in abstract coordinates.
o previ
The location of a mousedown in this plane, to compute the extent of a drag that may occur; in pixel coordinates.
o SX
The width, in abstract units, of the boundary plane display.
o SY
The height, in abstract units, of the boundary plane display.
o usecalcmaxpow
A boolean telling if we should use the calcmaxpow or some other choice, to be found in chosenmaxpow.
o X
The width, in pixels, of the boundary plane display.
o Y
The height, in pixels, of the boundary plane display.
o z11
The (1,1) entry of the element cannonically associated with the current trace.

Constructor Index

o BoundaryPanel(Label, Choice, Choice)

Method Index

o paint(Graphics)
Paint the BoundaryPanel by painting the basic plane, calling the paint on each of the current negative and positive BoundaryCircles, then drawing the tickmarks.
o update()
Recreates the current positive and negative BoundaryCircles and then repaints, called when some relevant parameter has changed.
o zoom(double)
Scales the size of the visible window onto the boundary of hyperbolic space.
