PseudoClass (Java SE 10 & JDK 10 ) (original) (raw)

• java.lang.Object

• • javafx.css.PseudoClass

• ---

public abstract class PseudoClass
extends Object
PseudoClass represents one unique pseudo-class state. Introducing a pseudo-class into a JavaFX class only requires that the methodNode.pseudoClassStateChanged(javafx.css.PseudoClass, boolean) be called when the pseudo-class state changes. Typically, thepseudoClassStateChanged method is called from theprotected void invalidated() method of one of the property base classes in the javafx.beans.property package.
Note that if a node has a default pseudo-class state, a horizontal orientation for example, pseudoClassStateChanged should be called from the constructor to set the initial state.
The following example would allow "xyzzy" to be used as a pseudo-class in a CSS selector.

  public boolean isMagic() {  
       return magic.get();  
   }  
   public BooleanProperty magicProperty() {  
       return magic;  
   }  
   public BooleanProperty magic =  
       new BooleanPropertyBase(false) {  
       @Override protected void invalidated() {  
           pseudoClassStateChanged(MAGIC_PSEUDO_CLASS. get());  
       }  
       @Override public Object getBean() {  
           return MyControl.this;  
       }  
       @Override public String getName() {  
           return "magic";  
       }  
   }  
   private static final PseudoClass  
       MAGIC_PSEUDO_CLASS = PseudoClass.getPseudoClass("xyzzy");
