All Implemented Interfaces:

public class URLChooser

extends DefaultTraversablePanel

implements GridBagConstants

The URLChooser is a replacement file chooser for JFileChooser. The URLChooser is designed to work in terms of URL rather than File instances.

In general, most client code should not call the URLChooser constructors directly. Instead, use one of the DialogUtil.newURLChooser() variants, as this ensures that the chooser will be initialized consistently throughout the application. When the URLChooser must be subclassed, however, the constructors can be called directly but this should be followed by a call to DialogUtil.initURLChooser(URLChooser,oracle.ide.Context).

Constructor Detail

URLChooser

public URLChooser()

Constructs a default URLChooser with all file system roots as reported by URLFileSystem.listRoots(). No default (directory or file) is set.

URLChooser

public URLChooser(java.net.URL defaultSelection)

Constructs a default URLChooser with all file system roots as reported by URLFileSystem.listRoots(). The specified URL is used as the default selection; if null, there will be no default selection.

URLChooser

public URLChooser(java.net.URL[] roots,
                  java.net.URL defaultSelection)

Constructs a URLFilter to display the specified array of URLs as its "root" file systems and the specified URL as the default selection. The "root" file systems only need to be directories and don't necessarily have to be actual file system roots.

URLChooser

public URLChooser(java.net.URL defaultSelection,
                  boolean showJarsAsDirs)

Deprecated. Replace with URLChooser(URL) and setShowJarsAsDirs(boolean).

URLChooser

public URLChooser(java.net.URL[] roots,
                  java.net.URL defaultSelection,
                  boolean showJarsAsDirs)

Deprecated. Replace with URLChooser(URL[],URL) and setShowJarsAsDirs(boolean).

Method Detail

setExtraURLs

public void setExtraURLs(java.net.URL[] extraURLs)

Registers a URL array that corresponds to resources that exist only in memory and not in the file system (for example, unsaved files). While it is allowable to register a URL for a resource that physically does exist, it is not recommended for performance reasons.

Nonexistent extra resources registered in this manner will appear in the URLChooser file list in italic font. This allows the user to distinguish between actual file system resources and in-memory only resources.

Extra resources should be registered each time the URLChooser becomes displayed, and they should be cleared each time it becomes undisplayed. Displayability changes to the URLChooser can be detected by adding a HierarchyListener to it with Component.addHierarchyListener(java.awt.event.HierarchyListener).

Parameters:

extraURLs - the URL array specifying all in-memory only resources, or null to clear the previously registered URLs.

See Also:

HierarchyEvent.SHOWING_CHANGED

getExtraURLs

public java.net.URL[] getExtraURLs()

Returns an array containing all URLs that have been registered as "extra" URLs; returns null if no URLs have previously been registed via setExtraURLs(URL[]).

setDialogRunnerCallback

public void setDialogRunnerCallback(DialogRunnerCallback callBack)

getDialogRunnerCallback

public DialogRunnerCallback getDialogRunnerCallback()

setShowJarsAsDirs

public void setShowJarsAsDirs(boolean showJarsAsDirs)

Sets whether the URLChooser should allow browsing into archives.

getShowJarsAsDirs

public boolean getShowJarsAsDirs()

Returns whether the URLChooser allows browsing into archives.

accept

public boolean accept(java.net.URL url)

Returns true if the specified URL should be displayed in the URLChooser. Returns false otherwise.

addChooseableURLFilter

public void addChooseableURLFilter(URLFilter filter)

Adds the specified URLFilter to be one of the filters that are shown in the "File type" combo box. If the specified filter is null or if the specified filter has already been added, this method does nothing.

clearChooseableURLFilters

public void clearChooseableURLFilters()

Clears the list of chooseable URLFilters.

getChooseableURLFilters

public URLFilter[] getChooseableURLFilters()

Returns all of the URLFilters shown in the "File type" combo box as an array. If there are no filters, then an empty array is returned.

addShortcutButton

public void addShortcutButton(javax.swing.Icon icon,
                              java.lang.String description,
                              java.net.URL url)

This method adds a shortcut button to the button panel on the left side of the URLChooser. When the user clicks on the shortcut button, the current location of the URLChooser will be changed to be the URL URL. If the specified URL is null, this method does nothing. If no shortcut buttons are added, then the shortcut panel is not drawn.

removeShortcutButtons

public void removeShortcutButtons()

Removes all shortcut buttons from the button panel on the left side of the URLChooser, allowing the URLChooser instance to be reused in a different context without retaining the existing shortcut buttons. The shortcut panel will no longer be visible after calling this method.

approveSelection

public boolean approveSelection()

Returns:

true if the URLChooser is ready to be dismissed; false if the user's current selection only indicates that a custom wildcard filter or directory change should occur instead.

cancelSelection

public void cancelSelection()

This method is called when the URLChooser is being canceled.

changeToParentDirectory

public void changeToParentDirectory()

getSelectedURL

public java.net.URL getSelectedURL()

Returns the URL of the node (which may be a directory or a file) that is currently selected in the URLChooser.

getFileNameURL

public java.lang.String getFileNameURL()

Returns:

The text of the file edit box. This is to allow listeners that care about the file filter to change the extension.

setFileNameURL

public void setFileNameURL(java.lang.String text)

getSelectedURLs

public java.net.URL[] getSelectedURLs()

Returns an array of URLs representing the current selections in the URLChooser. This array will contain only one element if there is only one selection or if the user typed the name of the file into the text field.

setSelectionMode

public void setSelectionMode(int selectionMode)

Sets the selection mode for the URLChooser. By default, the URLChooser allows multiple interval selection.

Parameters:

selectionMode - The specified mode must be one of MULTIPLE_INTERVAL_SELECTION, SINGLE_INTERVAL_SELECTION, or SINGLE_SELECTION.

Throws:

java.lang.IllegalArgumentException - if the specified selection mode is not one of the legal vales.

setRoots

public void setRoots(java.net.URL[] roots)

Sets the root URLs that will be traversed by the URLChooser. The roots can be any URL that represents a directory. Even directories within jar files are allowed.

setSelectedURL

public void setSelectedURL(java.net.URL selection)

Sets the selected directory such that the specified URL is shown in the file list. If the URL itself is a directory, then that directory is selected.

setSelectionScope

public void setSelectionScope(int selectionScope)

Valid values are FILES_ONLY and DIRECTORIES_ONLY. Note: This method must be called from the AWT event thread.

setURLFilter

public void setURLFilter(URLFilter filter)

Sets the active URLFilter. If the filter isn't on the list of filters used by the URLChooser it is first added. If the specified URLFilter is null, the default "all files" filter is set as the current filter.

flush

public void flush()

Clears the results of all file system queries that have been cached by the URLChooser, so a single chooser instance can be reused multiple times in a session. It is not necessary to use this method for a chooser instance that is used only once and then released.

This method is generally called immediately after a call to showOpenDialog() or showSaveDialog() has completed. If it is called before showing the chooser dialog, then it should be called before any other initialization of the chooser is done.

showOpenDialog

public int showOpenDialog(java.awt.Component parent)

Returns:

APPROVE_OPTION, CANCEL_OPTION, or ERROR_OPTION.

showOpenDialog

public int showOpenDialog(java.awt.Component parent,
                          java.lang.String title)

Returns:

APPROVE_OPTION, CANCEL_OPTION, or ERROR_OPTION.

showOpenDialog

public int showOpenDialog(java.awt.Component parent,
                          Traversable content,
                          java.lang.String title)

Returns:

APPROVE_OPTION, CANCEL_OPTION, or ERROR_OPTION.

showSaveDialog

public int showSaveDialog(java.awt.Component parent)

Returns:

APPROVE_OPTION, CANCEL_OPTION, or ERROR_OPTION.

showSaveDialog

public int showSaveDialog(java.awt.Component parent,
                          java.lang.String title)

Returns:

APPROVE_OPTION, CANCEL_OPTION, or ERROR_OPTION.

showSaveDialog

public int showSaveDialog(java.awt.Component parent,
                          Traversable content,
                          java.lang.String title)

Returns:

APPROVE_OPTION, CANCEL_OPTION, or ERROR_OPTION.

canonicalizeApprovalURL

protected java.net.URL canonicalizeApprovalURL(java.net.URL url)

Template helper method for approveSelection() to canonicalize the URL to be approved.

The default implementation calls URLFileSystem.canonicalize(URL). Subclasses may override to provide differing behavior.

getApprovalFileListURL

protected java.net.URL getApprovalFileListURL()

Template helper method for approveSelection() and getSelectedURL() to get the URL of the selected node in the file list.

The default implementation gets the URL of the selected node in the file list. Subclasses may wish to override to return null in order to ignore the file list selection.

checkApprovalParentExists

protected boolean checkApprovalParentExists(java.net.URL url)

Template helper method for approveSelection() to check that the parent directory for the approval URL exists.

The default implementation gets the parent of the specified URL via URLFileSystem.getParent(URL) and tests for that directory's existence with URLFileSystem.exists(URL). Subclasses may override to provide differing behavior (for example, to always return true if the parent directory need not exist).

addURLChooserListener

public void addURLChooserListener(oracle.ide.net.URLChooserListener ucl)

Add a URLChooserListener to this URLChooser

removeURLChooserListener

public void removeURLChooserListener(oracle.ide.net.URLChooserListener ucl)

Remove a URLChooserListener from this URLChooser

addNotify

public void addNotify()

Overrides:

addNotify in class javax.swing.JComponent

removeNotify

public void removeNotify()

Overrides:

removeNotify in class javax.swing.JComponent

getSelectedFilter

public final URLFilter getSelectedFilter()

Returns the URLFilter that is currently selected in the file type combo box. The value returned by this method should always be non-null.
