public class JInternalDisplay

extends JInternalFrame

implements Display

A JInternalFrame that can display Form- and MenuSheets.

This display allows SalesPoints to be displayed on a JDesktopPane.

The frame will display one FormSheet. Closing the frame using the systems menu or any other OS dependent gesture will result in a call to FormSheet.cancel() on the FormSheet.

Also, the frame may display a MenuSheet. It can therefore be used wherever a Display can be used.

Attention: This class is not meant to be serialized. See load() and store() for details.

v3.1

Field Detail

m_lhListeners

protected ListenerHelper m_lhListeners

The list of listeners.

Constructor Detail

JInternalDisplay

public JInternalDisplay()

Creates a new JInternalDisplay. Its default close operation will be set to DO_NOTHING_ON_CLOSE. Instead an InternalFrameListener will be added that executes exitForm() when the JInternalDisplay is closed and onDisplayFocusGained() when it is activated.

Method Detail

onDisplayFocusGained

protected void onDisplayFocusGained()

Executed when the JInternalDisplay receives the focus, i.e. is being activated. Does nothing by default.

save

public void save(ObjectOutputStream oos)
          throws IOException

Saves this display frame to the given output stream. The frame will only store information from which contents and layout can be restored later. The actual frame or any other Swing components will not be stored into the stream.

Specified by:

save in interface Display

Throws:

IOException

Override:

Sometimes Override this method whenever you added attributes that need to be saved when making the Shop persistent. Should be overridden along with load().

load

public void load(ObjectInputStream ois)
          throws IOException,
                 ClassNotFoundException

Restore this display frame from data in the given input stream.

Specified by:

load in interface Display

Parameters:

ois - the stream to read attributes from

Throws:

IOException

ClassNotFoundException

Override:

Sometimes Override this method whenever you added attributes. Should be overridden along with save().

setPrimaryTitle

public void setPrimaryTitle(String sPrimaryTitle)

Sets the display's primary title. The title will be displayed in the title bar.

The whole title will be displayed as follows: primaryTitle - secondaryTitle

Parameters:

sPrimaryTitle - the primary title to be set.

getPrimaryTitle

public String getPrimaryTitle()

Returns the display's primary title.

setSecondaryTitle

public void setSecondaryTitle(String sSecondaryTitle)

Sets the display's secondary title. The title will be displayed in the title bar.

The whole title will be displayed as follows: primaryTitle - secondaryTitle

getSecondaryTitle

public String getSecondaryTitle()

Returns the display's secondary title.

setDisplayTitle

public void setDisplayTitle()

Sets the display's title. It computes the whole title string from the primary and secondary title and assigns it to the actual JInternalFrame.

exitForm

protected void exitForm()

Hook method called when the display is about to be closed.

By default cancels any FormSheet being currently displayed and closes the frame.

setFormSheet

public void setFormSheet(FormSheet fs)
                  throws InterruptedException

Sets and displays a FormSheet.

This method should attach a FormSheetContainer as the FormSheet's display, get the FormSheet's caption, component and button bar and render them. The entire peer creation should be synchronized using FormSheet.getComponentLock() and FormSheet.getButtonsLock(), so as not to loose any events.

If fs.waitResponse() returns true, setFormSheet() should block, until the FormSheet is closed by a matching call to a closeFormSheet() method.

If a FormSheet is already being displayed, setFormSheet() should cancel this FormSheet prior to setting the new FormSheet.

Specified by:

setFormSheet in interface Display

Parameters:

fs - the FormSheet to be displayed.

Throws:

InterruptedException - if an interrupt occured while waiting for the FormSheet to be closed.

Override:

Always

getFormSheet

public FormSheet getFormSheet()

Returns the FormSheet that is currently attached to the display.

Specified by:

getFormSheet in interface Display

closeFormSheet

public void closeFormSheet()

Closes the current FormSheet. It is up to the display whether the FormSheet will be cancelled or just closed normally.

Specified by:

closeFormSheet in interface Display

Override:

Always

popUpFormSheet

public void popUpFormSheet(FormSheet fs)
                    throws InterruptedException

Opens a fresh JDisplayDialog and displays the FormSheet in it.

Specified by:

popUpFormSheet in interface Display

Parameters:

fs - the FormSheet to be displayed.

Throws:

InterruptedException - if an interrupt occured while waiting for the FormSheet to be closed.

Override:

Never

setMenuSheet

public void setMenuSheet(MenuSheet ms)

Sets and displays a MenuSheet.

If a MenuSheet is already being displayed, setMenuSheet() should remove this MenuSheet prior to setting the new MenuSheet.

Specified by:

setMenuSheet in interface Display

Parameters:

ms - the MenuSheet to be displayed. null is a valid value and should result in the current MenuSheet being closed.

Override:

Always

getMenuSheet

public MenuSheet getMenuSheet()

Returns the MenuSheet that is currently attached to the display.

Specified by:

getMenuSheet in interface Display

isUseableDisplay

public boolean isUseableDisplay()

Returns true to indicate this is a useable display.

Specified by:

isUseableDisplay in interface Display

Override:

Never

toFront

public void toFront()

Gives the display the focus, i.e. brings it to front and activates it.

Specified by:

toFront in interface Display

addFormSheetListener

public void addFormSheetListener(FormSheetListener fsl)

Adds a listener to receive notification on the JInternalDisplay's FormSheet.

Specified by:

addFormSheetListener in interface Display

Parameters:

fsl - the FormSheetListener to be registered.

Override:

Never

removeFormSheetListener

public void removeFormSheetListener(FormSheetListener fsl)

Removse a listener to receive notification on the JInternalDisplay's FormSheet.

Specified by:

removeFormSheetListener in interface Display

Parameters:

fsl - the FormSheetListener to be unregistered.

Override:

Never

fireFormSheetSet

protected void fireFormSheetSet(FormSheet fs)

Fires an event to all FormSheetListeners indicating that a FormSheet was set on this display. As FormSheet setting is always explicit, no extra parameter is necessary.

Parameters:

fs - the FormSheet that was set

Override:

Never

fireFormSheetRemoved

protected void fireFormSheetRemoved(FormSheet fs,
                                    boolean fExplicit)

Fires an event to all FormSheetListeners indicating that a FormSheet was removed from this display.

Parameters:

fs - the FormSheet that was set

fExplicit - true, if the FormSheet was closed explicitly, i.e. either by a call to one of the closeFormSheet methods or by setFormSheet (null).

See Also:

closeFormSheet(), closeFormSheet(FormSheet), setFormSheet(sale.FormSheet)

Override:

Never

closeFormSheet

public void closeFormSheet(FormSheet fs)

Closes a FormSheet.
