public class MySpinner
extends JSpinner

This spinner fires an action event when it comes to rest. It is based on JSpinner arrow listener. Additionally, it does away with some very stupid implementation in the classic spinner, e.g. setting a step width that is smaller than the number of digits displayed in the default formatter now work. Nevertheless, the entire API is somehow spoilt, so this workaropund does not work if the model is extracted later from the spinner.

Method Summary

private void	adaptFormat(Number stepsize) We set the number format to be used along with the editor text field to have at least the number of digits the step-size implies.
void	addActionListener(ActionListener al)
void	removeActionListener(ActionListener al)
Object	resetToOriginalValue() This sets the spinner value to the first explicetly set value.
void	setActionCommand(String name)
void	setStepSize(Object s) We allow setting the step size explicetly, instead of catching change events on the spinner model itself.

Method Detail

setActionCommand

public void setActionCommand(String name)

addActionListener

public void addActionListener(ActionListener al)

removeActionListener

public void removeActionListener(ActionListener al)

wasUp

public boolean wasUp(ActionEvent ae)

If this action event was generated by the button down, return true. Needed to detect the value that was displayed, which is getNext.

resetToOriginalValue

public Object resetToOriginalValue()

This sets the spinner value to the first explicetly set value.

setValue

public void setValue(Object to)

We cache the first call to this method's value.

Overrides:

setValue in class JSpinner

setStepSize

public void setStepSize(Object s)

We allow setting the step size explicetly, instead of catching change events on the spinner model itself. Changing the step size by explicetly invoking getModel().setStepSize() will not alter the step-size formatter. Additionally, we set the column number in the text field to hold at least the number of columns we need.

adaptFormat

private void adaptFormat(Number stepsize)

We set the number format to be used along with the editor text field to have at least the number of digits the step-size implies.

wasDown

public boolean wasDown(ActionEvent ae)

If this action event was generated by the button down, return true. Needed to detect the value that was displayed, which is getPrevious.
