I have a data bound Grid. Changing the value of a cell fires the onItemCodeChanged(). I can store the index of each row as row's data. Is there a way to retrieve directly the index of the row?
public void onItemCodeModified(InputEvent event) {
Row row = (Row)event.getTarget().getParent();
Integer index = (Integer)row.getValue();
.....
}
Here is a simple snippet to get an idea.
ZUL code
<grid id="gridContacts" fixedLayout="true" vflex="true" model="@{ yourmodel }" >
<columns sizable="true">
<column label="Code" width="100px" />
<column label="First Name" width="200px" />
<column label="Last Name" width="250px" />
<column width="100px" />
</columns>
<rows>
<row self="@{each='contact'}" value="@{ selectedContact }">
<label value="@{ record.code }" />
<toolbarbutton label="@{ contact.firstname }" forward="onClick=onEditContact" />
<toolbarbutton label="@{ contact.lastname }" forward="onClick=onEditContact" />
<button label="Delete Line" forward="onClick=onDeleteContact" />
</row>
</rows>
</grid>
The composer code
public void onEditContact(Event event) {
Contact contact = getSelectedContact(event);
....
edit the selected contact
....
}
public void onDeleteContact(Event event) {
Contact contact = getSelectedContact(event);
....
delete the selected contact
....
}
private Contact getSelectedContact(Event event) {
if (event instanceof ForwardEvent) {
ForwardEvent fwevent = (ForwardEvent)event;
Event eventOrigin = fwevent.getOrigin();
Row row = (Row) eventOrigin.getTarget().getParent();
Contact selectedContact = (Contact) row.getValue();
return selectedContact;
}
return null;
}
Hope that helps
