Hi , Good Day Experts!
I have a Question : How to make class that extends generated class implements View become a Windows view?
Here is my Code, I used vaadin designer to generate my design html , then I have Generated Class and Subclass View:
I have Four classes :-
[/color]
a) CustomerForm.java ( Generated class from vaadin designer)
b) CustomerFormView.java ( subclass controller)
c) CustomerSearch.java ( Generated class from vaadin designer)
d) CustomerSearchView.java ( Subclass controller to search)
[color=#000000]
- First of all, i wanted to add a function from class CustomerSearchView.java where User will click a button Update and will load a windows from class CustomerView.java as a form with update , how to make a class that extends view can be Windows?
1.1. CustomerSearchView.java
[/color]
[code]
HorizontalLayout horizon= new HorizontalLayout();
Button updateCustomer= new Button(new ThemeResource(“…/sample/img/updateCust.gif”));
updateCustomer.addStyleName(“nobackgroundTable”);
updateCustomer.setDescription(“Edit Customer”);
demo.addClickListener(new ClickListener() {
@Override
public void buttonClick(ClickEvent event) {
Notification.show(“Edit user”);
CustomerFormView.open((Customer)itemId, false);
}
});
[/code]
2. CustomerFormView.java
....
public class CustomerFormView extends CustomerForm implements View {
// constructor
@SuppressWarnings("serial")
public CustomerFormView(final Customers customer,final boolean preferencesTabOpen) {
// my controller to add data to forms.
}
public static void open(final Customers customer, final boolean preferencesTabActive) {
DashboardEventBus.post(new CloseOpenWindowsEvent());
Windows w =new CustomerFormView(customer, preferencesTabActive);
UI.getCurrent().addWindow(w);
w.focus();
}
Error Occurred at this line :
Window w =new PatientRegistrationView(person, preferencesTabActive);
UI.getCurrent().addWindow(w);
