Class EPNG

java.lang.Object
  echopointng.EPNG

public class EPNG
extends java.lang.Object

EPNG contains static members that help control the EPNG component library.

Field Summary

static MutableStyleSheet	DEFAULT_STYLESHEET This MutableStyleSheet contains the default visual representation of the EPNG components.
static StyleSheet	FALLBACK_STYLESHEET This StyleSheet is used as the fall back stylesheet by the EPNG rendering peers.

Method Summary

static Style	getFallBackStyle(Component component) This static helper method can be used to quickly get the Style for a given component from the FALLBACK_STYLESHEET.
static java.lang.Object	getRP(Component c, java.lang.String propertyName) This helper method will look for rendered properties inside the component (via getRenderproperty) and then if it finds null, then it will look in the fallback style for that component class.

Field Detail

FALLBACK_STYLESHEET

public static StyleSheet FALLBACK_STYLESHEET

This StyleSheet is used as the fall back stylesheet by the EPNG rendering peers. The EPNG rendering peers use the following lookup algorythmn for find non null property values.

• Look in the component's local properties
• Failing that, look in the component's local style
• Failing that, look in the application instance stylesheet
• Failing that, look in the fallback stylesheet

Hence this fall back stylesheet is the place of last resort for property values and you can override them by setting values in the component, component style or application instance stylesheet.

You are free to change this field or remove it by setting it to null. You can also set a change the Style for a specific component class using the addStyle() methods of the stylsheet.

However remember it is a static field and hence will affect all EPNG components in the same JVM.

DEFAULT_STYLESHEET

public static MutableStyleSheet DEFAULT_STYLESHEET

This MutableStyleSheet contains the default visual representation of the EPNG components.

Method Detail

getFallBackStyle

public static Style getFallBackStyle(Component component)

This static helper method can be used to quickly get the Style for a given component from the FALLBACK_STYLESHEET. If any of these objects is null, then null is returned.

Parameters:

component - - the component to get a fallback style for

Returns:

a fallback style for the component

getRP

public static java.lang.Object getRP(Component c,
                                     java.lang.String propertyName)

This helper method will look for rendered properties inside the component (via getRenderproperty) and then if it finds null, then it will look in the fallback style for that component class.

Parameters:

c - - the component in question

propertyName - - the name of the property to find a value for

Returns:

- the render value in question
