public class Bulbs
extends java.applet.Applet

This applet displays a pair of bulbs separated by stopcock.

Applet Parameters

NAME	Variable Type	Default	Description
BGColor	String	null	String containing a representation of an integer describing the RGB color for the applet background.
HoleDiameter	int	4	Diameter in pixels of the hole in the stopcock.
IsReady	String		JavaScript variable that will be set to true when applet has initialized. Must use MAYSCRIPT in APPLET tag to use this feature.
LeftColor	String	#FFA0A0	String containing a representation of an integer describing the RGB color of the gas in the left bulb.
LeftDiameter	int	0	Diameter in pixels of the left bulb. If the value is zero, the applet automatically sets the diameter to fill the available area.
LeftVolume	double	1.0	Volume in liters for the left bulb. The volume of the right bulb is determined by the volume of the left bulb and the relative diameters of the two bulbs.
MixtureColor	String	#A0A0FF	String representation of an integer describing the RGB color of the gas mixture, which the gas when the stopcock is open.
RightColor	String	#A0FFA0	String representation of an integer describing the RGB color of the gas in the right bulb.
RightDiameter	int	0	Diameter in pixels of the right bulb. If the value is zero, the applet automatically sets the diameter so the bulb fills the available display.
StopcockBorder	int	3	Width in pixels of the extent of the stopcock above and below the tube.
StopcockDiameter	int	10	Diameter in pixels of the body of the stopcock.
StopcockWidth	int	16	Width in pixels of the stopcock knob in the open position.
TubeLength	int	20	Length in pixels of the tube bearing the stopcock and situated between the two bulbs.
TubeWidth	int	8	Width in pixels of the tube bearing the stopcock and situated between the two bulbs.

setDiameters

public void setDiameters(int _leftDiameter,
                         int _rightDiameter)

Sets the diameters of the two bulbs. Using zero for either values results in the bulb size being set to fill the display area. The stopcock is set to the closed state.

Parameters:

_leftDiameter - diameter in pixels of the left bulb

_rightDiameter - diameter in pixels of the right bulb

setLeftColor

public void setLeftColor(java.lang.String _color)

Sets the color of the gas in the left bulb. This color is applied only if the stopcock is closed.

Parameters:

_color - integer value used to construct color

setLeftColor

                         int _green,
                         int _blue)

Sets the color of the gas in the left bulb. This color is applied only if the stopcock is closed.

Parameters:

_red - red component of the color

_green - green component of the color

_blue - blue component of the color

setLeftVolume

public void setLeftVolume(double _volume)

Sets the volume of the left bulb. Changing this value also changes the volume of the right bulb. The relative volumes of the two bulbs are established by the relative diameters of the two bulbs.

Parameters:

_volume - volume in liters of left bulb

setMixtureColor

Sets the color of the gas mixture. This color is applied only if the stopcock is open.

Parameters:

_red - red component of the color

_green - green component of the color

_blue - blue component of the color

setRightColor

public void setRightColor(java.lang.String _color)

Sets the color of the gas in the right bulb. This color is applied only if the stopcock is closed.

Parameters:

_color - integer value used to construct color

Parameters:

_red - red component of the color

_green - green component of the color

_blue - blue component of the color

setRightVolume

public void setRightVolume(double _volume)

Sets the volume of the right bulb. Changing this value also changes the volume of the left bulb. The relative volumes of the two bulbs are established by the relative diameters of the two bulbs.

Parameters:

_volume - volume in liters of right bulb

setStopcockState

public void setStopcockState(boolean _state)
