Constructor Detail

Spinner

public Spinner()

Construct a Spinner object.

Method Detail

addNotify

public void addNotify()

Overridden to add a KeyListener for key stroke events in the contained text field.

getCurrentDoubleValue

public double getCurrentDoubleValue()

Get the contents of d_currentDoubleValue.

Returns:

the current double value.

getCurrentText

public String getCurrentText()

Get the current text from the Spinner.

Returns:

A String containing the text of the currently selected Spinner value

getTextField

protected TextField getTextField()

Get reference to internal TextField object. This method became necessary because the call to updateText() which is used widely in this source file seems to result in the cursor being positioned to the beginning of the text field instead of leaving it where it was.

See Also:

symantec.itools.awt.util.spinner

setCurrentDoubleValue

public void setCurrentDoubleValue(double value)
                           throws PropertyVetoException

Sets the current double value.

Parameters:

value - Value contains the value to set d_currentDoubleValue to.

Throws:

PropertyVetoException - if the new value is greater than the specified maximum value

addKeyListener

public void addKeyListener(KeyListener keyListener)

Add a key listener to this component.

Parameters:

keyListener - a new listener for this component

See Also:

KeyListener

scrollUp

protected void scrollUp()

Increments the spinner's value and handles wrapping as needed.

See Also:

scrollDown(), Spinner.increment

scrollDown

protected void scrollDown()

Decrements the spinner's value and handles wrapping as needed.

See Also:

scrollUp(), Spinner.increment

qtyListSpinner_keyPressed

void qtyListSpinner_keyPressed(KeyEvent event)

Preprocess key events before they are passed to the TextField. Keypress events are passed to this method before being handed to the TextField so that this method can throw away invalid key strokes. This class is a floating point numeric entry spinner class so the only keys that are allowed are numeric (0-9), decimal point (.) BACKSPACE and END keys. The reason the END key is allowed is because the cursor seems to default to the beginning of the field when it is first displayed.

qtyListSpinner_keyReleased

void qtyListSpinner_keyReleased(KeyEvent event)

Perform post processing of keypress. Listen for key released events from the textfield in the spinner and set the value of the spinner to the current value in the text field. When the instruction pointer lands in this method, the text field already contains the new character that the user just entered, assuming it was not filtered out by the above keyPressed() handler.

RestoreField

private void RestoreField(Exception e)

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a listener for all property change events.

Parameters:

listener - the listener to add

See Also:

removePropertyChangeListener(java.beans.PropertyChangeListener)

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes a listener for all property change events.

Parameters:

listener - the listener to remove

addPropertyChangeListener(java.beans.PropertyChangeListener)
