Default constructor

addCustomOverrideListener(CustomOverrideListener)

Register a listener for the CustomOverride event.

addPropertyChangeListener(PropertyChangeListener)

Register a listener for the PropertyChange event.

firePropertyChange()

Report that we have been modified to any interested listeners.

getAsText()

getCustomEditor()

A PropertyEditor may chose to make available a full custom Component that edits its property value.

getJavaInitializationString()

This method is intended for use when generating Java code to set the value of the property.

getObject()

getPropInitializationCode(Object)

getTags()

If the property value must be one of a set of known tagged values, then this method should return an array of the tag values.

getValue()

getVisualObject()

invokeHelp()

implementation of HelpProvider interface

isPaintable()

main(String[])

paintValue(Graphics, Rectangle)

Paint a representation of the value into a given area of screen real estate.

propertyChange(PropertyChangeEvent)

Implementation of propertyChange method.

removeCustomOverrideListener(CustomOverrideListener)

Set (or change) the object that is to be edited.

setVisualObject(VisualObject)

supportsCustomEditor()

public DerivColBeanSourceColumnsEditor()

Default constructor

public void addCustomOverrideListener(CustomOverrideListener listener)

Register a listener for the CustomOverride event. The customizer should fire a CustomOverride event to notify an OK event

Parameters:

listener - An object to be invoked when a CustomOverride event is fired.

public synchronized void addPropertyChangeListener(PropertyChangeListener listener)

Register a listener for the PropertyChange event. The class will fire a PropertyChange value whenever the value is updated.

Parameters:

listener - An object to be invoked when a PropertyChange event is fired.

public void firePropertyChange()

Report that we have been modified to any interested listeners.

Parameters:

source - The PropertyEditor that caused the event.

public java.lang.String getAsText()

Returns:

The property value as a string suitable for presentation to a human to edit.

Returns "null" is the value can't be expressed as a string.

If a non-null value is returned, then the PropertyEditor should be prepared to parse that string back in setAsText().

public java.awt.Component getCustomEditor()

A PropertyEditor may chose to make available a full custom Component that edits its property value. It is the responsibility of the PropertyEditor to hook itself up to its editor Component itself and to report property value changes by firing a PropertyChange event.

The higher-level code that calls getCustomEditor may either embed the Component in some larger property sheet, or it may put it in its own individual dialog, or ...

Returns:

A java.awt.Component that will allow a human to directly edit the current property value. May be null if this is not supported.

public java.lang.String getJavaInitializationString()

This method is intended for use when generating Java code to set the value of the property. It should return a fragment of Java code that can be used to initialize a variable with the current property value.

Example results are "2", "new Color(127,127,34)", "Color.orange", etc.

Returns:

A fragment of Java code representing an initializer for the current value.

public java.lang.Object getObject()

public static java.lang.String getPropInitializationCode(Object propValue)

public java.lang.String[] getTags()

If the property value must be one of a set of known tagged values, then this method should return an array of the tag values. This can be used to represent (for example) enum values. If a PropertyEditor supports tags, then it should support the use of setAsText with a tag value as a way of setting the value.

Returns:

The tag values for this property. May be null if this property cannot be represented as a tagged value.

public java.lang.Object getValue()

Returns:

The value of the property.

public com.symantec.itools.vcafe.openapi.VisualObject getVisualObject()

public void invokeHelp()

implementation of HelpProvider interface

public boolean isPaintable()

Returns:

True if the class will honor the paintValue method.

public static void main(String[] args)

public void paintValue(Graphics gfx,
                       Rectangle box)

Paint a representation of the value into a given area of screen real estate. Note that the propertyEditor is responsible for doing its own clipping so that it fits into the given rectangle.

If the PropertyEditor doesn't honor paint requests (see isPaintable) this method should be a silent noop.

Parameters:

gfx - Graphics object to paint into.

box - Rectangle within graphics object into which we should paint.

public void propertyChange(PropertyChangeEvent e)

Implementation of propertyChange method.

public void removeCustomOverrideListener(CustomOverrideListener listener)

Remove a listener for the CustomOverride event.

Parameters:

listener - The CustomOverride listener to be removed.

public synchronized void removePropertyChangeListener(PropertyChangeListener listener)

Remove a listener for the PropertyChange event.

Parameters:

listener - The PropertyChange listener to be removed.

public void setAsText(String text) throws IllegalArgumentException

Set the property value by parsing a given String. May raise java.lang.IllegalArgumentException if either the String is badly formatted or if this kind of property can't be expressed as text.

Parameters:

text - The string to be parsed.

public void setObject(Object object)

public void setValue(Object value)

Set (or change) the object that is to be edited.

Parameters:

value - The new target object to be edited. Note that this object should not be modified by the PropertyEditor, rather the PropertyEditor should create a new object to hold any modified value.

public void setVisualObject(VisualObject visualObject)

public boolean supportsCustomEditor()

Returns:

True if the propertyEditor can provide a custom editor.
