public Image getValue()

Description copied from class: java.beans.PropertyEditorSupport

Gets the value of the property.

Specified by:

getValue in interface PropertyEditor

Overrides:

Returns:

The value of the property.

setValue

public void setValue(Object object)

Description copied from class: java.beans.PropertyEditorSupport

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

Specified by:

setValue in interface PropertyEditor

Overrides:

setValue in class PropertyEditorSupport

Parameters:

object - 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.

setAsText

public void setAsText(String text)
               throws IllegalArgumentException

Description copied from class: java.beans.PropertyEditorSupport

Sets 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.

Specified by:

setAsText in interface PropertyEditor

Overrides:

setAsText in class PropertyEditorSupport

Parameters:

text - The string to be parsed.

Throws:

IllegalArgumentException

getAsText

public String getAsText()

Specified by:

getAsText in interface PropertyEditor

Overrides:

getAsText in class PropertyEditorSupport

Returns:

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

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

paintValue

public void paintValue(Graphics graphics,
                       Rectangle r)

Description copied from class: java.beans.PropertyEditorSupport

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.

Specified by:

Overrides:

paintValue in class PropertyEditorSupport

Parameters:

getCustomEditor

public Component getCustomEditor()

Description copied from class: java.beans.PropertyEditorSupport

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 ...

Specified by:

getCustomEditor in interface PropertyEditor

Overrides:

getCustomEditor in class PropertyEditorSupport

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.
