public final class UploaderMain
extends javax.swing.JFrame
implements java.awt.event.ActionListener
extends javax.swing.JFrame
implements java.awt.event.ActionListener

Main (UI) class of JWS-based exhibit uploader. Runs as a Swing App using JNLP resource-access facilities such as persistence and file read/write.

This class/file contains as little non-UI code as is reasonably practical, so that if we change the UI details then other classes should be unaffected.

Derived initially from Sun's "WebPad" sample JWS/JNLP code.

We don't really want/need this class to be Serializable, but this class inherits Serializable from JFrame.

Field Detail

logger

private final SimpleLoggerIF logger

Central logger instance for uploader; never null. This instance may log to the status bar and elsewhere.

JWS_UPLOAD_ONLY

static final boolean JWS_UPLOAD_ONLY

If true, only allow upload in a JWS environment.

See Also:: Constant Field Values

logic

private final UploaderLogic logic

Our companion "business-logic" class; never null.

selectAction

private final SelectAction selectAction

The action performed by the "Select" button.

aboutAction

private final AboutAction aboutAction

The action performed by the "About" menu entry.

exitAction

private final ExitAction exitAction

The action performed by the "Exit" menu entry.

lbb

private final LocaleBeanBase lbb

Select our locale; never null.

status

private final javax.swing.JLabel status

Status bar; never null.

sisListener

private final UploaderMain.SISListener sisListener

Single listener instance.

uib

final UploadInfoBean uib

Bean to hold our current view of the exhibit we are naming; never null.

autoSuffixCheckBox

private final javax.swing.JCheckBox autoSuffixCheckBox

Contains user-selected auto/manual file-type extraction; never null.

mouseHandler

private final UploaderMain.MouseHandler mouseHandler

Handles Mouse over messages on toolbar buttons and menu items; never null.

BG_RO_COL

private static final java.awt.Color BG_RO_COL

Background colour we set for read-only informational areas. We use this to avoid confusion with data-entry areas.

We may co-ordinate this with the Web site uploader colours.

uploadTableEditRow

private final java.util.concurrent.atomic.AtomicInteger uploadTableEditRow

Row marked for editing in uploadTable; -1 if none; never null. Should be ignored if out of range for the current table content.

We use AtomicInteger for lockless thread-safety.

uploadTableModel

private final javax.swing.table.AbstractTableModel uploadTableModel

The table model instance for the files selected for upload; never null. This doesn't hold any data itself, simply interfaces to the data in logic.selectedFiles.

Call fireTableDataChanged() or something more fine-grained when the data has changed to allow proper redrawing.

queueTableModel

private final javax.swing.table.AbstractTableModel queueTableModel

The table model for the files queued for upload; never null. This doesn't hold any data itself, simply interfaces to the data in logic.uploadingFiles.

Call fireTableDataChanged() or something more fine-grained when the data has changed to allow proper redrawing.

APPLICATION_WINDOW_TITLE

private static final java.lang.String APPLICATION_WINDOW_TITLE

Title shown for application.

See Also:: Constant Field Values

TEXT_ENTRY_TIMEOUT_MS

private static final int TEXT_ENTRY_TIMEOUT_MS

Idle time in text entry box before we take opportunity to show updates, ms; strictly positive.

See Also:: Constant Field Values

ENABLE_FILE_DROP

private static final boolean ENABLE_FILE_DROP

If true, try to enable file drag-and-drop into the table. This may not be allowed, eg in the JNLP/JWS sandbox.

See Also:: Constant Field Values

pollAL

private final java.awt.event.ActionListener pollAL

ActionListener invoked by pollUI; never null.

serialVersionUID

private static final long serialVersionUID

Unique Serialisation class ID generated by http://random.hd.org/.

See Also:: Constant Field Values

Constructor Detail

UploaderMain

private UploaderMain()

Create an instance of the Uploader app main window. Designed to be called by main().

Method Detail

shutdown

private void shutdown()
               throws java.lang.UnsupportedOperationException

Perform any activity required to shut down cleanly, eg save state, then exit. This should try to avoid taking a long time.

This may throw an UnsupportedOperationException to try to veto an exit that the user changes their mind about, eg because we have work in progress!

Throws:: java.lang.UnsupportedOperationException - if the user vetoes the shut-down

initActions

private void initActions()

This method should be called before creating the UI to create all the Actions.

registerAction

private void registerAction(JLFAbstractAction action)

createMenu

private javax.swing.JMenuBar createMenu()

Create the application menu bar.

createMainPane

private Tuple.Pair<javax.swing.JComponent,java.awt.event.ActionListener> createMainPane()

Create the (main) tabbed pane component and a lister for UI polling.

createStatusPanel

private Tuple.Pair<javax.swing.JComponent,java.awt.event.ActionListener> createStatusPanel()

Make the login/status component; never null. Also creates a listener suitable to poll regularly from the Swing thread to do async UI updates.

createChooserPanel

private Tuple.Pair<javax.swing.JComponent,java.awt.event.ActionListener> createChooserPanel()

Make the chooser/naming component; never null. Also creates a listener suitable to poll regularly from the Swing thread to do async UI updates.

createProgressPanel

private Tuple.Pair<javax.swing.JComponent,java.awt.event.ActionListener> createProgressPanel()

Make the progress component; never null. Also creates a listener suitable to poll regularly from the Swing thread to do async UI updates.

makeStandardInsets

private static java.awt.Insets makeStandardInsets()

Make the standard insets to wrap round most components. Note that the returned Insets() object is mutable.

createStatusBar

private javax.swing.JLabel createStatusBar()

Creates and initialises a status bar.

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent evt)

This method acts as the Action handler delegate for all the actions.

Specified by:: actionPerformed in interface java.awt.event.ActionListener

selectFilesForUpload

private void selectFilesForUpload()

Select (in a file-chooser) some files for upload. Since we will have to interact with disc, eg to compute hashes, this may take a while for many and/or large files.

pollUI

private void pollUI(java.awt.event.ActionEvent e)

Poll UI (in Swing thread, ie Swing-safe).

main

public static void main(java.lang.String[] args)

Main method invoked from JWS.
