How do i add clickhandler to Apply button of datetimeitem picker?

smartgwt pro5.0, 2014-09-11

I'm trying, but getting an error here's what i do:

final DateTimeItem inField = (DateTimeItem) editor.getForms().get(0).getField(Constants.FIELD_INTIME);
      
DateChooser inPicker = new DateChooser();
inPicker.getApplyButton().addIconClickHandler(new com.smartgwt.client.widgets.events.IconClickHandler() {
    @Override
    public void onIconClick(com.smartgwt.client.widgets.events.IconClickEvent iconClickEvent) {
        SC.say("APPLY!! HAHAHAAAAA");
    }
});

inField.setPickerProperties(inPicker);

However, i get this error:
java.lang.IllegalStateException: Cannot access property applyButton before the widget has been created.

But i created it myself?

Am i missing something obvious?


EDIT: what i'm trying to accomplish is putting a clickhandler on the "apply" so that i can manually set the "intime" value as a starting-value for the "outtime" field, if it is empty. It will save time for the users.

Hi mathias,

this is most likely an AutoChild use case.

Hey Blama. Yeah with AutoChild did manage to get something to happen. The problem, though, is that i want to just ADD another clickhandler, to the apply button in the datechooser, but leave all the other functionality intact. With my autochild-code, it seems that if i click on "apply", only my new handler is called, the rest has been removed.

Anybody have any smart ideas?

My code:

final DateTimeItem inField = (DateTimeItem) editor.getForms().get(0).getField(ServerConstants.FIELD_INTIME);
final DateTimeItem outField = (DateTimeItem) editor.getForms().get(0).getField(ServerConstants.FIELD_OUTTIME);

final DateChooser inPicker = new DateChooser();

IButton applyButton = new IButton();
applyButton.addClickHandler(new ClickHandler() {
    @Override
    public void onClick(ClickEvent clickEvent) {
        if(outField.getValue() == null){
            outField.setValue(inPicker.getData());
        }
    }
});
inPicker.setAutoChildProperties("applyButton", applyButton);
inField.setAutoChildProperties("picker", inPicker);
//inField.setPickerProperties(inPicker);

Hi mathias,

sorry, no idea how to get the "default" AutoChild in order to modify it and send it back via setAutoChildProperties.

Ok, thanks anyway. Iso, any idea how i go about adding an additional clickhandler to the "Apply" button of a DateChooser for a DateTimeFormItem? I'm out of ideas.

Bumping this in hope that someone has time to give me some insight.
