Constructor Detail

JArcDial

public JArcDial(double start,
                double end)

constructs a dial with no pointers; the pointers will move inside a given range.

Parameters:

start - starting value of the dial

end - end value of the dial

Method Detail

setArc

public void setArc(double start,
                   double stop)

Define the positions at which the the dial scale will start and stop. The angles must be such that stop>start. Counter-clockwise dials can be created by inverting the start and stop values (not angles!) in the constructor.

Parameters:

start - the angle (from the top, clockwise, in rads) where the scale start

stop - the angle (from the top, clockwise, in rads) where the scale will end

setSize

public void setSize(int w,
                    int h)

as described in java.awt.Component

Overrides:

setSize in class java.awt.Component

setSize

public void setSize(java.awt.Dimension d)

as described in java.awt.Component

Overrides:

setSize in class java.awt.Component

getPreferredSize

public java.awt.Dimension getPreferredSize()

as described in java.awt.Component

Overrides:

getPreferredSize in class javax.swing.JComponent

setMinorTickSpacing

public void setMinorTickSpacing(double s)

set the spacing between minor tics

Parameters:

s - the spacing between minor tics

setMajorTickSpacing

public void setMajorTickSpacing(double s)

set the spacing between major tics

Parameters:

s - the spacing between major tics

setPaintMinorTicks

public void setPaintMinorTicks(boolean b)

show the minor tics?

Parameters:

b - show the minor tics?

setPaintMajorTicks

public void setPaintMajorTicks(boolean b)

show the major tics?

Parameters:

b - show the major tics?

setPaintLabels

public void setPaintLabels(boolean b)

show the tic labels?

Parameters:

b - show the tic labels?

paintComponent

public void paintComponent(java.awt.Graphics g)

draw the component - don't call this directly, but use repaint()

Overrides:

paintComponent in class javax.swing.JComponent

addJPointer

public void addJPointer(JPointer p)

add a pointer; it will be the actual component that contains informations

Parameters:

p - the pointer that must be added

removeJPointer

public void removeJPointer(JPointer p)

remove a pointer; it should have been added with addJPointer()

Parameters:

p - the pointer that must be removed

main

public static void main(java.lang.String[] args)
