 @JavaBean(defaultProperty="UIClassID", description="A component which allows for the editing of a single line of text.") public class JTextField extends JTextComponent implements SwingConstants JTextFieldis a lightweight component that allows the editing of a single line of text. For information on and examples of using text fields, see How to Use Text Fields in The Java Tutorial.JTextFieldis intended to be source-compatible withjava.awt.TextFieldwhere it is reasonable to do so. This component has capabilities not found in thejava.awt.TextFieldclass. The superclass should be consulted for additional capabilities.JTextFieldhas a method to establish the string used as the command string for the action event that gets fired. Thejava.awt.TextFieldused the text of the field as the command string for theActionEvent.JTextFieldwill use the command string set with thesetActionCommandmethod if notnull, otherwise it will use the text of the field as a compatibility withjava.awt.TextField.The method setEchoCharandgetEchoCharare not provided directly to avoid a new implementation of a pluggable look-and-feel inadvertently exposing password characters. To provide password-like services a separate classJPasswordFieldextendsJTextFieldto provide this service with an independently pluggable look-and-feel.The java.awt.TextFieldcould be monitored for changes by adding aTextListenerforTextEvent's. In theJTextComponentbased components, changes are broadcasted from the model via aDocumentEventtoDocumentListeners. TheDocumentEventgives the location of the change and the kind of change if desired. The code fragment might look something like:DocumentListener myListener = ??; JTextField myArea = ??; myArea.getDocument().addDocumentListener(myListener);The horizontal alignment of JTextFieldcan be set to be left justified, leading justified, centered, right justified or trailing justified. Right/trailing justification is useful if the required size of the field text is smaller than the size allocated to it. This is determined by thesetHorizontalAlignmentandgetHorizontalAlignmentmethods. The default is to be leading justified.How the text field consumes VK_ENTER events depends on whether the text field has any action listeners. If so, then VK_ENTER results in the listeners getting an ActionEvent, and the VK_ENTER event is consumed. This is compatible with how AWT text fields handle VK_ENTER events. If the text field has no action listeners, then as of v 1.3 the VK_ENTER event is not consumed. Instead, the bindings of ancestor components are processed, which enables the default button feature of JFC/Swing to work. Customized fields can easily be created by extending the model and changing the default model provided. For example, the following piece of code will create a field that holds only upper case characters. It will work even if text is pasted into from the clipboard or it is altered via programmatic changes. public class UpperCaseField extends JTextField { public UpperCaseField(int cols) { super(cols); } protected Document createDefaultModel() { return new UpperCaseDocument(); } static class UpperCaseDocument extends PlainDocument { public void insertString(int offs, String str, AttributeSet a) throws BadLocationException { if (str == null) { return; } char[] upper = str.toCharArray(); for (int i = 0; i < upper.length; i++) { upper[i] = Character.toUpperCase(upper[i]); } super.insertString(offs, new String(upper), a); } } }Warning: Swing is not thread safe. For more information see Swing's Threading Policy. 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.beanspackage. Please seeXMLEncoder.

getColumnWidthprotected int getColumnWidth() Returns the column width. The meaning of what a column is can be considered a fairly weak notion for some fonts. This method is used to define the width of a column. By default this is defined to be the width of the character m for the font used. This method can be redefined to be some alternative amount- Returns:
- the column width >= 1
 
 - 
getPreferredSizepublic Dimension getPreferredSize() Returns the preferred sizeDimensionsneeded for thisTextField. If a non-zero number of columns has been set, the width is set to the columns multiplied by the column width.- Overrides:

getActionListeners@BeanProperty(bound=false) public ActionListener[] getActionListeners() Returns an array of all theActionListeners added to this JTextField with addActionListener().- Returns:
- all of the ActionListeners added or an empty array if no listeners have been added
- Since:

- command- the command string
 
 - 
setAction@BeanProperty(visualUpdate=true, description="the Action instance connected with this ActionEvent source") public void setAction(Action a) Sets theActionfor theActionEventsource. The newActionreplaces any previously setActionbut does not affectActionListenersindependently added withaddActionListener. If theActionis already a registeredActionListenerfor theActionEventsource, it is not re-registered.Setting the Actionresults in immediately changing all the properties described in Swing Components SupportingAction. Subsequently, the textfield's properties are automatically updated as theAction's properties change.This method uses three other methods to set and help track the Action's property values. It uses theconfigurePropertiesFromActionmethod to immediately change the textfield's properties. To track changes in theAction's property values, this method registers thePropertyChangeListenerreturned bycreateActionPropertyChangeListener. The defaultPropertyChangeListenerinvokes theactionPropertyChangedmethod when a property in theActionchanges.- Parameters:
- a- the- Actionfor the- JTextField, or- null
- Since:
- 1.3
