Method Detail

setContainedModel

protected final void setContainedModel(java.lang.String property,
                                       ModelBase containedModel)

For internal use only.

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

Adds a PropertyChangeListener to the listener list. The listener is registered for all properties.

A PropertyChangeEvent will get fired in response to setting a bound property, such as setFont, setBackground, or setForeground. Note that if the current component is inheriting its foreground, background, or font from its container, then no event will be fired in response to a change in the inherited property.

Parameters:

listener - the PropertyChangeListener to be added

removePropertyChangeListener

public void removePropertyChangeListener(java.beans.PropertyChangeListener listener)

Removes a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.

Parameters:

listener - the PropertyChangeListener to be removed

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  java.lang.Object oldProperty,
                                  java.lang.Object newProperty)

Support for reporting bound property changes. This method can be called when a bound property has changed and it will send the appropriate PropertyChangeEvent to any registered PropertyChangeListeners.

Parameters:

propertyName - the property being changed

oldProperty - the value being changed from

newProperty - the value being changed to

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  ModelBase oldProperty,
                                  ModelBase newProperty)

Support for reporting bound contained-Model property changes. This method can be called when a bound property has changed and it will send the appropriate PropertyChangeEvent to any registered PropertyChangeListeners.

Parameters:

propertyName - the property being changed

oldProperty - the value being changed from

newProperty - the value being changed to

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  double oldProperty,
                                  double newProperty)

Reports a bound property change for a double property.

Parameters:

propertyName - the property being changed

oldProperty - the value being changed from

newProperty - the value being changed to

firePropertyChange(java.lang.String, java.lang.Object, java.lang.Object)

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  boolean oldProperty,
                                  boolean newProperty)

Reports a bound property change for a String property.

Parameters:

propertyName - the property being changed

oldProperty - the value being changed from

newProperty - the value being changed to

firePropertyChange(java.lang.String, java.lang.Object, java.lang.Object)

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  int oldProperty,
                                  int newProperty)

Reports a bound property change for an int property.

Parameters:

propertyName - the property being changed

oldProperty - the value being changed from

newProperty - the value being changed to

firePropertyChange(java.lang.String, java.lang.Object, java.lang.Object)

equals

public boolean equals(java.lang.Object obj)

Determines whether another object is equal to this ModelBase.

The result is true if and only if the argument is not null and is a ModelBase object that has the same properties as this object.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to test for equality with this ModelBase

Returns:

true if the objects are the same; false otherwise.

hashCode

public int hashCode()

Computes the hash code for this ModelBase.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.
