Method Detail

getTags

public String[] getTags()

Description copied from class: java.beans.PropertyEditorSupport

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.

Specified by:

getTags in interface PropertyEditor

Overrides:

getTags in class PropertyEditorSupport

Returns:

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

getValue

public Paint getValue()

Description copied from class: java.beans.PropertyEditorSupport

Gets the value of the property.

Specified by:

getValue in interface PropertyEditor

Overrides:

getValue in class PropertyEditorSupport

Returns:

The value of the property.

getJavaInitializationString

public String getJavaInitializationString()

Description copied from class: java.beans.PropertyEditorSupport

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.

Specified by:

getJavaInitializationString in interface PropertyEditor

Overrides:

getJavaInitializationString in class PropertyEditorSupport

Returns:

A fragment of Java code representing an initializer for the current 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()

Description copied from class: java.beans.PropertyEditorSupport

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

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.

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().

paintValue

public void paintValue(Graphics gfx,
                       Rectangle box)

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:

paintValue in interface PropertyEditor

Overrides:

paintValue in class PropertyEditorSupport

Parameters:

gfx - Graphics object to paint into.

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

isPaintable

public boolean isPaintable()

Description copied from class: java.beans.PropertyEditorSupport

Determines whether the class will honor the painValue method.

Specified by:

isPaintable in interface PropertyEditor

Overrides:

isPaintable in class PropertyEditorSupport

Returns:

True if the class will honor the paintValue method.
