Hi everyone,
For my application, I am adding a suggestbox on the front interface so when
user types in any letter corresponding list (we won't add the list to the
interface. It will be shown as the user types in and changes
correspondingly when the letters changes as we generally see in online
websites) matching to that letter needs to appear on the front interface. I
am using keydownhandler event to obtain this.As you can see the below code,
I am making an RPC call to obtain the list of data from the oracle database
. Suppose user has typed in letter 'D' the following query runs
"String sql = "select NAME from DOM_REFERENCE_TABLE where DESCRIPTION =
'NationalAccountDetails' AND NAME LIKE upper ('" + tablename +"%') ORDER BY
NAME ASC";
where tablename value is 'D', so it gets all values starting with letter
'D' from database. This list will then be added to the oracle
(MultiWordSuggestOracle) object as shown in the below code(see at Response
of RPC call Tag). So, the problem is the list that needs to appear when
user types in letter'D' doesn't happen for the first time but happens when
user types in Next time. I guess you people understood what I am trying to
say. As the list gets added to oracle with keydown event it is not showing
at that time but it will show for next event. But I need the matching list
to be shown in the same event. How can I achieve this? Any suggestions? Let
me know I need to clarify more on this. Thanks in advance
Code:
// Object Declaration
private MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();
private SuggestBox suggestBox = new SuggestBox(oracle);
// Key down event:
suggestBox.addKeyDownHandler(new KeyDownHandler(){
public void onKeyDown(KeyDownEvent event) {
// TODO Auto-generated method stub
String tablename = suggestBox.getValue();
if (tablename != null && !tablename.isEmpty()) {
datamartClientImpl.retrieveNATLData(tablename);
}
}
});
// Response from RPC call
public void updateSuggestBox(DomesticDMAHistBean domesticDMAHistBean) {
oracle.addAll(domesticDMAHistBean.getNatldesc()); // obtaining the list
with startin letter 'D'
hPanel.remove(Metrics);
hPanel.remove(bttnDomesticNATLHist);
vPanel.clear();
vPanel.add(suggestBox);
hPanel.add(vPanel);
hPanel.add(Metrics);
hPanel.add(bttnDomesticNATLHist);
}
