Package Summary Overview Summary

### class:JFileChooser [NONE]
- All Implemented Interfaces: ImageObserver, MenuContainer, Serializable, Accessible
      public class JFileChooser
      extends JComponent
      implements Accessible
  `JFileChooser` provides a simple mechanism for the user to choose a file. For information about using `JFileChooser`, see How to Use File Choosers , a section in The Java Tutorial . The following code pops up a file chooser for the user's home directory that sees only .jpg and .gif images:
          JFileChooser chooser = new JFileChooser();
          FileNameExtensionFilter filter = new FileNameExtensionFilter(
              "JPG & GIF Images", "jpg", "gif");
          chooser.setFileFilter(filter);
          int returnVal = chooser.showOpenDialog(parent);
          if(returnVal == JFileChooser.APPROVE_OPTION) {
             System.out.println("You chose to open this file: " +
                  chooser.getSelectedFile().getName());
          }

Constructs a `JFileChooser` pointing to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix.

### constructor:JFileChooser(java.lang.String) [NONE]
- #### JFileChooser
      public JFileChooser(String currentDirectoryPath)
Constructs a `JFileChooser` using the given path. Passing in a `null` string causes the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix. Parameters: `currentDirectoryPath` - a `String` giving the path to a file or directory

### constructor:JFileChooser(java.io.File) [NONE]
- #### JFileChooser
      public JFileChooser(File currentDirectory)
Constructs a `JFileChooser` using the given `File` as the path. Passing in a `null` file causes the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix. Parameters: `currentDirectory` - a `File` object specifying the path to a file or directory

### constructor:JFileChooser(javax.swing.filechooser.FileSystemView) [NONE]
- #### JFileChooser
      public JFileChooser(FileSystemView fsv)
Constructs a `JFileChooser` using the given `FileSystemView`. Parameters: `fsv` - a `FileSystemView`

### constructor:JFileChooser(java.io.File, javax.swing.filechooser.FileSystemView) [NONE]
- #### JFileChooser
      public JFileChooser(File currentDirectory,
                          FileSystemView fsv)
Constructs a `JFileChooser` using the given current directory and `FileSystemView`. Parameters: `currentDirectory` - a `File` object specifying the path to a file or directory `fsv` - a `FileSystemView`

### constructor:JFileChooser(java.lang.String, javax.swing.filechooser.FileSystemView) [NONE]
- #### JFileChooser

                          FileSystemView fsv)
Constructs a `JFileChooser` using the given current directory path and `FileSystemView`. Parameters: `currentDirectoryPath` - a `String` specifying the path to a file or directory `fsv` - a `FileSystemView`

### method:setup(javax.swing.filechooser.FileSystemView) [NONE]
- #### setup
      protected void setup(FileSystemView view)
Performs common constructor initialization and setup. Parameters: `view` - the `FileSystemView` used for setup

### method:setDragEnabled(boolean) [NONE]
- #### setDragEnabled
      public void setDragEnabled(boolean b)
Sets the `dragEnabled` property, which must be `true` to enable automatic drag handling (the first part of drag and drop) on this component. The `transferHandler` property needs to be set to a non-`null` value for the drag to do anything. The default value of the `dragEnabled` property is `false`. When automatic drag handling is enabled, most look and feels begin a drag-and-drop operation whenever the user presses the mouse button over an item and then moves the mouse a few pixels. Setting this property to `true` can therefore have a subtle effect on how selections behave. Some look and feels might not support automatic drag and drop; they will ignore this property. You can work around such look and feels by modifying the component to directly call the `exportAsDrag` method of a `TransferHandler`. Parameters: `b` - the value to set the `dragEnabled` property to Throws: `HeadlessException` - if `b` is `true` and `GraphicsEnvironment.isHeadless()` returns `true` Since: 1.4 See Also: `GraphicsEnvironment.isHeadless()`, `getDragEnabled()`, `JComponent.setTransferHandler(javax.swing.TransferHandler)`, `TransferHandler`

### method:getDragEnabled() [NONE]

### method:setSelectedFile(java.io.File) [NONE]
- #### setSelectedFile
      public void setSelectedFile(File file)
Sets the selected file. If the file's parent directory is not the current directory, changes the current directory to be the file's parent directory. Parameters: `file` - the selected file See Also: `getSelectedFile()`

### method:getSelectedFiles() [NONE]
- #### getSelectedFiles
      public File[] getSelectedFiles()
Returns a list of selected files if the file chooser is set to allow multiple selection. Returns: an array of selected `File`s

### method:setCurrentDirectory(java.io.File) [NONE]
- #### setCurrentDirectory
      public void setCurrentDirectory(File dir)
Sets the current directory. Passing in `null` sets the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix. If the file passed in as `currentDirectory` is not a directory, the parent of the file will be used as the currentDirectory. If the parent is not traversable, then it will walk up the parent tree until it finds a traversable directory, or hits the root of the file system. Parameters: `dir` - the current directory to point to See Also: `getCurrentDirectory()`

### method:changeToParentDirectory() [NONE]
- #### changeToParentDirectory
      public void changeToParentDirectory()
Changes the directory to be set to the parent of the current directory. See Also: `getCurrentDirectory()`

### method:rescanCurrentDirectory() [NONE]
- #### rescanCurrentDirectory
      public void rescanCurrentDirectory()

### method:showOpenDialog(java.awt.Component) [NONE]
- #### showOpenDialog
      public int showOpenDialog(Component parent)
                         throws HeadlessException
Pops up an "Open File" file chooser dialog. Note that the text that appears in the approve button is determined by the L&F. Parameters: `parent` - the parent component of the dialog, can be `null`; see `showDialog` for details Returns: the return state of the file chooser on popdown: JFileChooser.CANCEL_OPTION JFileChooser.APPROVE_OPTION JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed Throws: `HeadlessException` - if GraphicsEnvironment.isHeadless() returns true. See Also: `GraphicsEnvironment.isHeadless()`, `showDialog(java.awt.Component, java.lang.String)`

### method:showSaveDialog(java.awt.Component) [NONE]
- #### showSaveDialog
      public int showSaveDialog(Component parent)
                         throws HeadlessException
Pops up a "Save File" file chooser dialog. Note that the text that appears in the approve button is determined by the L&F. Parameters: `parent` - the parent component of the dialog, can be `null`; see `showDialog` for details Returns: the return state of the file chooser on popdown: JFileChooser.CANCEL_OPTION JFileChooser.APPROVE_OPTION JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed Throws: `HeadlessException` - if GraphicsEnvironment.isHeadless() returns true. See Also: `GraphicsEnvironment.isHeadless()`, `showDialog(java.awt.Component, java.lang.String)`

### method:showDialog(java.awt.Component, java.lang.String) [NONE]
- #### showDialog
      public int showDialog(Component parent,
                            String approveButtonText)
                     throws HeadlessException
  Pops a custom file chooser dialog with a custom approve button. For example, the following code pops up a file chooser with a "Run Application" button (instead of the normal "Save" or "Open" button):
       filechooser.showDialog(parentFrame, "Run Application");
  Alternatively, the following code does the same thing:
          JFileChooser chooser = new JFileChooser(null);
          chooser.setApproveButtonText("Run Application");
          chooser.showDialog(parentFrame, null);
The `parent` argument determines two things: the frame on which the open dialog depends and the component whose position the look and feel should consider when placing the dialog. If the parent is a `Frame` object (such as a `JFrame`) then the dialog depends on the frame and the look and feel positions the dialog relative to the frame (for example, centered over the frame). If the parent is a component, then the dialog depends on the frame containing the component, and is positioned relative to the component (for example, centered over the component). If the parent is `null`, then the dialog depends on no visible window, and it's placed in a look-and-feel-dependent position such as the center of the screen. Parameters: `parent` - the parent component of the dialog; can be `null` `approveButtonText` - the text of the `ApproveButton` Returns: the return state of the file chooser on popdown: JFileChooser.CANCEL_OPTION JFileChooser.APPROVE_OPTION JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed Throws: `HeadlessException` - if GraphicsEnvironment.isHeadless() returns true. See Also: `GraphicsEnvironment.isHeadless()`

### method:createDialog(java.awt.Component) [NONE]
- #### createDialog
      protected JDialog createDialog(Component parent)
                              throws HeadlessException
  Creates and returns a new `JDialog` wrapping `this` centered on the `parent` in the `parent`'s frame. This method can be overriden to further manipulate the dialog, to disable resizing, set the location, etc. Example:
           class MyFileChooser extends JFileChooser {
               protected JDialog createDialog(Component parent) throws HeadlessException {
                   JDialog dialog = super.createDialog(parent);
                   dialog.setLocation(300, 200);
                   dialog.setResizable(false);
                   return dialog;
               }
           }
Parameters: `parent` - the parent component of the dialog; can be `null` Returns: a new `JDialog` containing this instance Throws: `HeadlessException` - if GraphicsEnvironment.isHeadless() returns true. Since: 1.4 See Also: `GraphicsEnvironment.isHeadless()`

- #### setControlButtonsAreShown
      public void setControlButtonsAreShown(boolean b)
Sets the property that indicates whether the approve and cancel buttons are shown in the file chooser. This property is `true` by default. Look and feels that always show these buttons will ignore the value of this property. This method fires a property-changed event, using the string value of `CONTROL_BUTTONS_ARE_SHOWN_CHANGED_PROPERTY` as the name of the property. Parameters: `b` - `false` if control buttons should not be shown; otherwise, `true` Since: 1.3 See Also: `getControlButtonsAreShown()`, `CONTROL_BUTTONS_ARE_SHOWN_CHANGED_PROPERTY`

### method:getDialogType() [NONE]
- #### getDialogType
      public int getDialogType()
Returns the type of this dialog. The default is `JFileChooser.OPEN_DIALOG`. Returns: the type of dialog to be displayed: JFileChooser.OPEN_DIALOG JFileChooser.SAVE_DIALOG JFileChooser.CUSTOM_DIALOG See Also: `setDialogType(int)`

### method:setDialogType(int) [NONE]
- #### setDialogType
      public void setDialogType(int dialogType)
Sets the type of this dialog. Use `OPEN_DIALOG` when you want to bring up a file chooser that the user can use to open a file. Likewise, use `SAVE_DIALOG` for letting the user choose a file for saving. Use `CUSTOM_DIALOG` when you want to use the file chooser in a context other than "Open" or "Save". For instance, you might want to bring up a file chooser that allows the user to choose a file to execute. Note that you normally would not need to set the `JFileChooser` to use `CUSTOM_DIALOG` since a call to `setApproveButtonText` does this for you. The default dialog type is `JFileChooser.OPEN_DIALOG`.
