Constructor Detail

DoubleSpinButton

public DoubleSpinButton(java.lang.Number min,
                        java.lang.Number max,
                        java.lang.Number step,
                        java.lang.Number initial)

Creates a new DoubleSpinButton based on the given values.

Parameters:

min - the minimum.

max - the maximum.

step - the step value.

initial - the initial value.

Method Detail

substract

protected java.lang.Number substract(java.lang.Number left,
                                     java.lang.Number right)

Description copied from class: com.tensegrity.gui.swing.control.spinbutton.AbstractSpinButton

Invoked by this class whenever its required to subtract a certain value from another. Since Java doesn't allow operator overloading, we have to implement the minus-operand by this method.

Parameters:

left - the first summand.

right - the second summand.

Returns:

the result of the subtraction of eft-right as an instance of Number.

add

protected java.lang.Number add(java.lang.Number left,
                               java.lang.Number right)

Description copied from class: com.tensegrity.gui.swing.control.spinbutton.AbstractSpinButton

Invoked by this class whenever its required to add a certain value to another. Since Java doesn't allow operator overloading, we have to implement the plus-operand by this method.

Parameters:

left - the first summand.

right - the second summand.

Returns:

the result of the addition of left+right as an instance of Number.

max

protected java.lang.Number max(java.lang.Number left,
                               java.lang.Number right)

Description copied from class: com.tensegrity.gui.swing.control.spinbutton.AbstractSpinButton

Invoked by this class whenever its required to determine the maximum of two values of type Number. This method should behave similar to the Math.max(int, int) (or double, float, etc.) method.

Parameters:

left - the first value.

right - the second value.

Returns:

the result of the max(left,right) as an instance of Number.

min

protected java.lang.Number min(java.lang.Number left,
                               java.lang.Number right)

Description copied from class: com.tensegrity.gui.swing.control.spinbutton.AbstractSpinButton

Invoked by this class whenever its required to determine the minimum of two values of type Number. This method should behave similar to the Math.min(int, int) (or double, float, etc.) method.

Parameters:

left - the first value.

right - the second value.

Returns:

the result of the min(left,right) as an instance of Number.
