Unexpected behavior using a RecordClickHandler with an ListGridField

[JayG]

Hello Everyone,

First of all, I am currently using Smart GWT Version “6.0p”.

What i have is a dropdown Grid that displays the reduced Data from the Datasource. (Somthing like this: http://www.smartclient.com/smartgwt/..._grid_category).
I want to add a ClickHandler, so an Action (In the Test-Code "doSomeCoolStuff") can be executed using the Clicked Record.
Also, I want the User to be able to use the Arrow Keys to navigate and execute the same Action using the "Enter" key.

So far I added a "RecordClickHandler" to the "ListGridField" and if I click the Record, I can execute a Method to work with the Record input.
But the "RecordClickHandler" also is executed when I am using the Arrow-Keys navigation through the Records.

So my Questions are:
1. Is there a RecordClickHandler, that only reacts, if the Record really is Clicked?
2. How can I Accomplish using the Accow-Keys to navigate through the List Grid and Execute an action with the currently selected Record, using the "Enter"-Key?

Test Project:
I recreated this problem within this a Test Project. Therefore, I modified the "DataSourceDMI"-Sample Code of Smartgwt, to get a good Datasource.
Also, I added the Click Handler like this: "itemField.addRecordClickHandler(event -> doSomeCoolStuff(event.getRecord()));"

In this Test Code the same behavior as described earlier can be seen:
I can reduce the Data and Click a Record to Execute the "doSomeCoolStuff" method.
Also, I can navigate through the Grid list and Execute the Command using the "Enter"-Key.
Till this point everything is what I want it to be.
But I noticed that the Handler also executed the "doSomeCoolStuff" method every time I used the Arrow Keys to navigate.

Code:

public class DataSourceDMI implements EntryPoint {
    public void onModuleLoad() {
        Layout layout = new VLayout();
        layout.setHeight100();
        layout.setWidth100();

        DataSource supplyItemDS = DataSource.get("supplyItemDMI");
          
        final DynamicForm form = new DynamicForm();  
        form.setWidth(300);  
  
        ListGridField itemField = new ListGridField("itemName");
        itemField.addRecordClickHandler(event -> doSomeCoolStuff(event.getRecord()));
        
        ListGridField unitsField = new ListGridField("units");  
        ListGridField unitCostField = new ListGridField("unitCost");  
  
        ComboBoxItem  item = new ComboBoxItem("itemID");  
        item.setWidth(240);  
        item.setTitle("Item");  
        item.setOptionDataSource(supplyItemDS);  
        item.setValueField("SKU");  
        item.setDisplayField("itemName");  
        item.setPickListWidth(450);  
        item.setPickListFields(itemField, unitsField, unitCostField);
        item.setCompleteOnTab(true);
        item.setShowTitle(false);
        item.setAutoFetchData(true);
        item.setMinimumSearchLength(3);
        item.setHideEmptyPickList(true);
  
        form.setItems(item);
  
        Layout layout = new Layout();
        layout.setWidth100();
        layout.setBorder("1px solid black");
        layout.setHeight("5%");
        layout.addMember(form);
        

        
        layout.draw();
    }

    public void doSomeCoolStuff(Record record) {
        GWT.log("Record Clicked: " + record.getAttributeAsString("itemName"));
    }
}

Thank you in advance!

You may use isc.EventHandler.getKey() inside recordClick to detect Arrow_Up, Arrow_Down, and Space key pressed.
Then consider that the Enter key triggers the recordDoubleClick handler.

Thank you for the Response claudiobosticco!

It was solved like this:

        private Record tempSelectedSearchRecord;
        ...

        ListGrid searchFieldGrid = new ListGrid();
        ...

        searchFieldGrid.setSelectionType(SelectionStyle.SINGLE);
        searchFieldGrid.addCellClickHandler(event -> {
            tempSelectedSearchRecord = null;
            doSomeCoolStuff(event.getRecord());
        });
        searchFieldGrid.addSelectionChangedHandler(event -> tempSelectedSearchRecord = event.getRecord());
        searchFieldGrid.addBodyKeyPressHandler(event -> {
            if ("Enter".equalsIgnoreCase(EventHandler.getKey()) && tempSelectedSearchRecord != null) {
                doSomeCoolStuff(tempSelectedSearchRecord);
                tempSelectedSearchRecord = null;
            }
        });

        item.setPickListProperties(searchFieldGrid);
        ...

But i still don't understand why a "RecordClickHandler" reacts to somethink that is no click.. does not make sense at all..

Anyway. Thanks again for the Replay!
