Method Detail

setBeep

public void setBeep(boolean b)

Sets whether to beep or not on invalid key presses

Parameters:

b - true to beep if invalid

allowNegativeNumbers

public void allowNegativeNumbers(boolean b)

Sets whether to allow negative numbers. Default is to allow them.

Parameters:

b - 'true' if it allows negatives; 'false' otherwise.

allowFloatingPointNumbers

public void allowFloatingPointNumbers(boolean b)

Sets whether to allow floating point numbers. Default is to allow them.

Parameters:

b - 'true' if it allows floating point numbers; 'false' otherwise.

keyTyped

public void keyTyped(KeyEvent e)

Invoked when a key has been typed. This event occurs when a key press is followed by a key release.

Specified by:

keyTyped in interface KeyListener

Parameters:

e - the KeyEvent to be processed.

keyPressed

public void keyPressed(KeyEvent e)

Invoked when a key has been pressed.

Specified by:

keyPressed in interface KeyListener

Parameters:

e - the KeyEvent to be processed.

keyReleased

Invoked when a key has been released.

Specified by:

keyReleased in interface KeyListener

Parameters:

e - the KeyEvent to be processed.

getDecimalValue

public float getDecimalValue()

Get the value as a numerical value. Even if it is an integer, the value value will be returned as a float. The caller is expected to cast it back to an integer. If the text field is empty, a value of Float.NAN is returned.

Returns:

The currently set value
