What if login link parent is not the same parent as the login panel...
for instance like 5 levels deep where passing it through all the
constructors is highly undesirable.
you have to pass a reference somehow. if you do not want to pass it down the
constructor chain then you cannot use it inside component constructor - so
you have to delay it until render time.
interface ILoginPanelContainer { LoginPanel getLoginPanel() }
class mypage extends webpage implements iloginpanelcontainer {
private final LoginPanel panel;
public mypage() { panel=new }
LoginPanel getLoginPanel() { return panel; }
}
class loginlink extends link {
LoginPanel findLoginPanel() {
iloginpanelprovider provider=null;
Component ancestor=getParent();
while (ancestor!=null) { if (ancestor isntanceof
iloginpanelprovider) { provider=ancestor; break; } }
return provider.getloginpanel();
}
onclick() {
panel=findloginpanel();
//fooo
}
}
