public class TextPreview
extends Component

Methods

o ask 
 public static File ask(JFrame parent,
                        String title,
                        File dfc,
                        ChangeListener target,
                        FileChooserFilter fcf)
Convenience method to prompt for the name of a text file. For example: 
File f = ImagePreview.ask(null,"Open file",previousFile,
                null,new FileChooserFilter("Config file (cfg)"));

Parameters:
fparent - the parent frame for the dialog box. fparent may be null if a default parent has been established with StandardDialog
description - a description string that will be shown to the user to indicate what is being requested
initial - the initial value for the string
columns - the default width (in 'm's) of the TextField
target - the ChangeListener that will be informed if the OK or Apply buttons are hit.
fcf - a FileChooserFilter for selecting the file names to be presented in the dialog box.
Returns:
If target is null, the dialog box will be modal and the method will return the final result, or null if cancelled. Otherwise, the dialog box is non-modal, the method returns null immediatly, and the listener is informed when appropriate. The source of the change event will be a FileChooser.
