| public void | setAccessory(javax.swing.JComponent newAccessory)Sets the accessory component. An accessory is often used to show a
preview image of the selected file; however, it can be used for anything
that the programmer wishes, such as extra custom file chooser controls.
Note: if there was a previous accessory, you should unregister
any listeners that the accessory might have registered with the
file chooser.
JComponent oldValue = accessory;

|

firePropertyChange(APPROVE_BUTTON_TOOL_TIP_TEXT_CHANGED_PROPERTY, oldValue, approveButtonToolTipText);
|
| 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.
if(controlsShown == b) {
return;
}
boolean oldValue = controlsShown;
controlsShown = b;
firePropertyChange(CONTROL_BUTTONS_ARE_SHOWN_CHANGED_PROPERTY, oldValue, controlsShown);
|
| public void | setCurrentDirectory(java.io.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.
File oldValue = currentDirectory;
if (dir != null && !dir.exists()) {
dir = currentDirectory;
}
if (dir == null) {

| public void | setDialogTitle(java.lang.String dialogTitle)Sets the string that goes in the JFileChooser window's
title bar.
String oldValue = this.dialogTitle;
this.dialogTitle = dialogTitle;
if(dialog != null) {
dialog.setTitle(dialogTitle);
}
firePropertyChange(DIALOG_TITLE_CHANGED_PROPERTY, oldValue, dialogTitle);
|
| 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.
if(this.dialogType == dialogType) {
return;
}
if(!(dialogType == OPEN_DIALOG || dialogType == SAVE_DIALOG || dialogType == CUSTOM_DIALOG)) {
throw new IllegalArgumentException("Incorrect Dialog Type: " + dialogType);

setApproveButtonText(null);

firePropertyChange(DIALOG_TYPE_CHANGED_PROPERTY, oldValue, dialogType);
|
| 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 a selection
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.
if (b && GraphicsEnvironment.isHeadless()) {
throw new HeadlessException();
}
dragEnabled = b;
|
| public void | setFileFilter(javax.swing.filechooser.FileFilter filter)Sets the current file filter. The file filter is used by the
file chooser to filter out files from the user's view.

| public void | setFileHidingEnabled(boolean b)Sets file hiding on or off. If true, hidden files are not shown
in the file chooser. The job of determining which files are
shown is done by the FileView.
// Dump showFilesListener since we'll ignore it from now on
if (showFilesListener != null) {

showFilesListener = null;
}
boolean oldValue = useFileHiding;
useFileHiding = b;
firePropertyChange(FILE_HIDING_CHANGED_PROPERTY, oldValue, useFileHiding);
|
| public void | setFileSelectionMode(int mode)Sets the JFileChooser to allow the user to just
select files, just select
directories, or select both files and directories. The default is
JFilesChooser.FILES_ONLY.
if(fileSelectionMode == mode) {
return;
}
if ((mode == FILES_ONLY) || (mode == DIRECTORIES_ONLY) || (mode == FILES_AND_DIRECTORIES)) {
int oldValue = fileSelectionMode;

| public void | setFileSystemView(javax.swing.filechooser.FileSystemView fsv)Sets the file system view that the JFileChooser uses for
accessing and creating file system resources, such as finding
the floppy drive and getting a list of root drives.
FileSystemView oldValue = fileSystemView;
fileSystemView = fsv;
firePropertyChange(FILE_SYSTEM_VIEW_CHANGED_PROPERTY, oldValue, fileSystemView);

FileView oldValue = this.fileView;
this.fileView = fileView;
firePropertyChange(FILE_VIEW_CHANGED_PROPERTY, oldValue, fileView);

not the current directory, changes the current directory
to be the file's parent directory.
File oldValue = selectedFile;

| public int | showDialog(java.awt.Component parent, java.lang.String approveButtonText)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.
if(approveButtonText != null) {
setApproveButtonText(approveButtonText);
setDialogType(CUSTOM_DIALOG);
}
dialog = createDialog(parent);
dialog.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
returnValue = CANCEL_OPTION;
}
});
returnValue = ERROR_OPTION;
rescanCurrentDirectory();
dialog.show();
dialog.dispose();
dialog = null;
return returnValue;
