public BorderlessTextField(String value, int n)

Method Detail

setBorderback to summary
public void setBorder(Border b)

Overrides javax.swing.JComponent.setBorder.

Doc from javax.swing.JComponent.setBorder.

Sets the border of this component. The Border object is responsible for defining the insets for the component (overriding any insets set directly on the component) and for optionally rendering any border decorations within the bounds of those insets. Borders should be used (rather than insets) for creating both decorative and non-decorative (such as margins and padding) regions for a swing component. Compound borders can be used to nest multiple borders within a single component.

Although technically you can set the border on any object that inherits from JComponent, the look and feel implementation of many standard Swing components doesn't work well with user-set borders. In general, when you want to set a border on a standard Swing component other than JPanel or JLabel, we recommend that you put the component in a JPanel and set the border on the JPanel.

This is a bound property.

Parameters
b:Border

the border to be rendered for this component

setTextback to summary
public void setText(String s)

Overrides javax.swing.text.JTextComponent.setText.

Doc from javax.swing.text.JTextComponent.setText.

Sets the text of this TextComponent to the specified text. If the text is null or empty, has the effect of simply deleting the old text. When text has been inserted, the resulting caret location is determined by the implementation of the caret class.

Note that text is not a bound property, so no PropertyChangeEvent is fired when it changes. To listen for changes to the text, use DocumentListener.

Parameters
s:String

the new text to be set

Known Direct Subclasses
javax.swing.plaf.synth.SynthComboBoxUI.SynthComboBoxEditor
Annotations
@SuppressWarnings:serial
A subclass of BasicComboBoxEditor that implements UIResource. BasicComboBoxEditor doesn't implement UIResource directly so that applications can safely override the cellRenderer property with BasicListCellRenderer subclasses.

Warning

Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see java.beans.XMLEncoder.
