thanks Michael this does the job...in this code, now I've other doubt
public class MyWindow extends Window
{
public MyWindow() // <--- not clear where I need declare it
{
super("My Window!");
Panel horizontalPanel = new Panel(new Border.Invisible(),
Panel.Orientation.HORIZONTAL);
Panel leftPanel = new Panel(new Border.Bevel(true),
Panel.Orientation.VERTICAL);
Panel middlePanel = new Panel(new Border.Bevel(true),
Panel.Orientation.VERTICAL);
Panel rightPanel = new Panel(new Border.Bevel(true),
Panel.Orientation.VERTICAL);
horizontalPanel.addComponent(leftPanel);
horizontalPanel.addComponent(middlePanel);
horizontalPanel.addComponent(rightPanel);
addComponent(horizontalPanel); // <----this is a confusing part too
}
}
in this code addComponent(horizontalPanel) is basically something like
this.addComponent(horizontalPanel)
does clojure have the "this" reference??...how can I call the
constuctor...I'm thinkingin something like this
(defn MyWindow []
(proxy [Window] ["My windows!!"]
(MyWindow [] (. this addComponent (Label. "Bang!!") ))))
is it wrong no? :D
thanks!!!
