public PwScalarField_IP()

Method Detail

init

public void init()

Description copied from class: PsPanel

Provides layout and adds internal components.

Overrides:

init in class PsPanel

setParent

public void setParent(PsUpdateIf parent)

Description copied from class: PjWorkshop_IP

Set parent of this panel which receives update events.

The method getFather() allows to retrieve this parent.

Specified by:

setParent in interface PsUpdateIf

Overrides:

setParent in class PjWorkshop_IP

Parameters:

parent - parent of this panel

See Also:

PsPanel.getFather()

update

public boolean update(java.lang.Object event)

Update the panel whenever the parent has changed somewhere else. Method is invoked from the parent or its superclasses.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PsPanel

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

See Also:

PsObject, PsUpdateIf.getFather(), PsUpdateIf.setParent(PsUpdateIf)

getNotice

public java.lang.String getNotice()

Informational text on the usage of the dialog. This notice will be displayed if this info panel is shown in a dialog. The text is split at line breaks into individual lines on the dialog.

This method return null and should be overwritten.

Overrides:

getNotice in class PjWorkshop_IP

Returns:

string with textual information.

getDialogSize

public java.awt.Dimension getDialogSize()

Get preferred size, for example, to ensure size of dialog.

Overrides:

getDialogSize in class PjWorkshop_IP

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent event)

Handle item state events invoked from choices, checkboxes, list items.

Specified by:

itemStateChanged in interface java.awt.event.ItemListener

actionPerformed

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

Description copied from class: PjWorkshop_IP

Catch action events fired by buttons of a dialog which displays this info panel. This method invokes a method of the parent workshop which correspond to the name of the pressed button.

Subclasses are advised to call super.actionPerformed() on any events, which they do not handle themselves, in order to let this method inform the workshop.

Subclasses may also catch dialog button events using a phrase

     if (event.getID() == PsDialog.BUTTON_OK) {
         ...                             // do their own business, but
         super.actionPerformed(event);   // still call super too.
     } 
 

For example, if a user presses the CANCEL button, then the dialog fires an action event to be received by this info panel or a subclass. The subclass may optionally perform some clean-up. If the subclass overwrites the actionPerformed method it should ensure that this info panel still receives the event via super.actionPerformed(). This class will catch the event and call workshop.cancel(). The workshop will then restore the original geometry and dispose itself. Finally the dialog will dispose itself in PsDialog.

On button-reset the method workshop.update(workshop) is invoked. This method must assure that all reset instance variables of a workshop update their dependencies.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Overrides:

actionPerformed in class PjWorkshop_IP
