one way might be to use a List<User> userList private variable in the
widget..
the state of the flextable is same as the state of the userList.
"when a row is selected".. depending on what event selects the row (mouse
over, mouseclick..).. update a private User currentUser object.
public class MyUserListView extends Composite {
private FlexTable userListTable;
private ArrayList<User> userList=new ArrayList<User>();
private User currentSelection;
public MyUserListView() {
userListTable=new FlexTable();
userListTable.setBorderWidth(1);
DOM.setStyleAttribute(userListTable.getElement(), "cursor",
"pointer");
initWidget(userListTable);
userListTable.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
Cell cellClicked= userListTable.getCellForEvent(event);
int rowIndex=cellClicked.getRowIndex();
currentSelection=userList.get(rowIndex);
Window.alert("U have choosen User:
"+currentSelection.getFirstname());
}
});
}
/**
* This will mostly be defined in the Presenter view interface.
* @param u
*/
public void addUserToUserTable(User u){
userList.add(u);
int row=userListTable.getRowCount();
userListTable.setWidget(row, 0, new HTML(u.getFirstname()));
userListTable.setWidget(row, 1, new HTML(u.getLastname()));
}
public User getCurrentSelection() {
return currentSelection;
}
}
in the client class that uses this widget,
MyUserListView mul=new MyUserListView();
mul.addUserToUserTable(new User("Firstname1","lastname1"));
mul.addUserToUserTable(new User("Firstname2","lastname2"));
mul.addUserToUserTable(new User("Firstname3","lastname3"));
mul.addUserToUserTable(new User("Firstname4","lastname4"));
mul.addUserToUserTable(new User("Firstname5","lastname5"));
outerPanel.add(mul);
There are a lot of limitations to this as, u can point out. but it sorts the
basic issue of maintaining the current state of "selected" row. there should
be better ways to handle this. Experts please comment.
Thanks,
Subhro.
