protected PropertyEditorSupport()
protected PropertyEditorSupport(Object source)
source
- The source to use for any events we fire.
Method Detail |
public void setValue(Object value)
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 Object getValue()
public boolean isPaintable()
public void paintValue(Graphics gfx, Rectangle box)
If the PropertyEditor doesn't honor paint requests (see isPaintable) this method should be a silent noop.
gfx
- Graphics object to paint into.
box
- Rectangle within graphics object into which we should paint.
public String getJavaInitializationString()
Example results are "2", "new Color(127,127,34)", "Color.orange", etc.
public String getAsText()
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 void setAsText(String text) throws IllegalArgumentException
text
- The string to be parsed.
public String[] getTags()
public Component getCustomEditor()
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 ...
public boolean supportsCustomEditor()
public void addPropertyChangeListener(PropertyChangeListener listener)
listener
- An object to be invoked when a PropertyChange
event is fired.
public void removePropertyChangeListener(PropertyChangeListener listener)
listener
- The PropertyChange listener to be removed.
public void firePropertyChange()
source
- The PropertyEditor that caused the event.
