Example of Path.getComponent
In the following code, when the button is clicked, its label will be changed.
<window id="w" apply="MyComposer">
<button id="b" label="ok" forward="onClick=onChangeLabel"/>
</window>
And MyComposer.java
import org.zkoss.zk.ui.Path;
import org.zkoss.zk.ui.util.GenericComposer;
import org.zkoss.zul.Button;
public class MyComposer extends GenericComposer {
Button btn = new Button();
public void onChangeLabel(){
btn = (Button)Path.getComponent("/w/b");
btn.setLabel("changed");
}
}
Another way, getFellow
getFellow is another api to get the component. But it is not recommended. For simplicity and consistency, use Path.getComponent instead.
omit Path.getComponent
