public final class WholeNumberField
extends oracle.bali.ewt.text.NumberTextField
WholeNumberField
is a subclass of a JTextField that only allow whole numbers (no negative numbers allowed.) The real work is done by NumberTextField
. Note that if you try to set a negative number in the field, either by the constructor or setValue()
, a value of zero will be set instead. To get negative numbers, use NumberTextField
instead.oracle.bali.ewt.text.NumberTextField.AccessibleNumberTextField

WholeNumberField(int columnWidth)
Constructs a new
WholeNumberField with the an initial value of 0, and the specified column width. |
WholeNumberField(int initialValue, int columnWidth)
Constructs a new
WholeNumberField with the specified initial value in the field and column width. |

java.awt.Dimension |
getMinimumSize()
Override the default sizing behavior so that if the number of columns (size) was provided when this control was created, then we will try to use that size (which happens to be the preferred size) if possible.
|
int |
getValue()
Retrieves the number in the text field.
|
void |
setValue(int value)
Sets the number in the text field to the specified value.
