All Implemented Interfaces:: ActionListener, EventListener, SwingConstants

public class FormView
extends ComponentView
implements ActionListener

Component decorator that implements the view interface for form elements, <input>, <textarea>, and <select>. The model for the component is stored as an attribute of the the element (using StyleConstants.ModelAttribute), and is used to build the component of the view. The type of the model is assumed to of the type that would be set by HTMLDocument.HTMLReader.FormAction. If there are multiple views mapped over the document, they will share the embedded component models.

The following table shows what components get built by this view.

Element Type	Component built
input, type button	JButton
input, type checkbox	JCheckBox
input, type image	JButton
input, type password	JPasswordField
input, type radio	JRadioButton
input, type reset	JButton
input, type submit	JButton
input, type text	JTextField
select, size > 1 or multiple attribute defined	JList in a JScrollPane
select, size unspecified or 1	JComboBox
textarea	JTextArea in a JScrollPane
input, type file	JTextField

```
public FormView(Element elem)
```
    Creates a new FormView object.
    
    Parameters:
    elem - the element to decorate
- Method Detail
  - createComponent
```
protected Component createComponent()
```
    Create the component. This is basically a big switch statement based upon the tag type and html attributes of the associated element.
    
    Overrides:
    
    createComponent in class ComponentView
  - getMaximumSpan
```
public float getMaximumSpan(int axis)
```
    Determines the maximum span for this view along an axis. For certain components, the maximum and preferred span are the same. For others this will return the value returned by Component.getMaximumSize along the axis of interest.
    
    Overrides:
    
    getMaximumSpan in class ComponentView
    
    Parameters:
    axis - may be either View.X_AXIS or View.Y_AXIS
    
    Returns:
    the span the view would like to be rendered into >= 0. Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.
    
    Throws:
    
    IllegalArgumentException - for an invalid axis
    See Also:
    View.getPreferredSpan(int)
  - actionPerformed
```
public void actionPerformed(ActionEvent evt)
```
    Responsible for processeing the ActionEvent. If the element associated with the FormView, has a type of "submit", "reset", "text" or "password" then the action is processed. In the case of a "submit" the form is submitted. In the case of a "reset" the form is reset to its original state. In the case of "text" or "password", if the element is the last one of type "text" or "password", the form is submitted. Otherwise, focus is transferred to the next component in the form.
    
    Specified by:
    
    actionPerformed in interface ActionListener
    
    Parameters:
    evt - the ActionEvent.
  - submitData
```
protected void submitData(String data)
```
    This method is responsible for submitting the form data. A thread is forked to undertake the submission.
  - imageSubmit
```
protected void imageSubmit(String imageData)
```
    This method is called to submit a form in response to a click on an image -- an <INPUT> form element of type "image".
    
    Parameters:
    imageData - the mouse click coordinates.
