Class PseudoClass
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 method
Node.pseudoClassStateChanged(javafx.css.PseudoClass, boolean) be called when the pseudo-class state changes. Typically, the pseudoClassStateChanged method is called from the protected 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");
