Field Detail

exportClasses

protected String[] exportClasses

optionsAccessory

protected FileOptionsAccessory optionsAccessory

The file options accessory used to display the options for a given file type.

Constructor Detail

ExportDialog

public ExportDialog()

ExportDialog

public ExportDialog(String creator)

Creates a new ExportDialog with all known export filetypes.

Parameters:

creator - The "creator" to be written into the header of the file (may be null)

ExportDialog

public ExportDialog(String creator,
                    boolean addAllExportFileTypes)

Creates a new ExportDialog with "Export..." as the title and as the "approve" button.

Parameters:

creator - The "creator" to be written into the header of the file (may be null)

addAllExportFileTypes - if true adds all known export filetypes to dialog.

Method Detail

addAllExportFileTypes

public void addAllExportFileTypes()

Adds all known export filetypes alphabetically to dialog.

addExportFileType

public void addExportFileType(ExportFileType newFileType)

Add a ExportFileType to this dialog.

showExportDialog

public void showExportDialog(Component parent,
                             Component saveTarget)

Show this dialog and save component as the given file type.

showExportDialog

public void showExportDialog(Component parent,
                             Component[] saveTargets)

Show this dialog and save component as the given file type.

showDialog

public boolean showDialog(Component parent)

Returns true if a file was chosen and no problems occured. Returns false if aborted by user or due to an error.

getPreferredSize

public Dimension getPreferredSize()

BUG FIX. The default size of the file chooser is too small and cuts off the buttons and file type chooser. This enlarges the preferred size of this panel. While this fixes the current problem, this is not the optimal solution. The value 400 comes from MetalFileChooserUI.LIST_MIN_WIDTH The value 100 comes from MetalFileChooserUI.LIST_MIN_HEIGHT which is look and feel dependent!

Overrides:

getPreferredSize in class JComponent

setCurrentDirectory

public void setCurrentDirectory(File dir)

A bug (not clear) in JDK 1.1 with swing1.1.1 throws a NullPointerException at the first propertychange with a null value. We catch the null value here and set the home dir

Overrides:

setCurrentDirectory in class JFileChooser

showDialog

public int showDialog(Component parent,
                      String approveButtonText)

BUG FIX (Bug ID#4284488). Override this method to get correct return value.

Overrides:

showDialog in class JFileChooser

approveSelection

public void approveSelection()

BUG FIX (Bug ID#4284488). Override this method to get correct return value.

Overrides:

approveSelection in class JFileChooser

cancelSelection

public void cancelSelection()

BUG FIX (Bug ID#4284488). Override this method to get correct return value.

Overrides:

cancelSelection in class JFileChooser
