DateBox getDatePicker() and setCurrentMonth()

[Lukasz Plotnicki]

Hi,

does anybody know, why I when I access the DatePicker of a DateBox via the getDatePicker() method and try to set it to show a specific month (via the setCurrentMonth(Date month) method), it simply does not work? Have I misunderstood the API? The setCurrentMonth() method works just fine if I use it on a DatePicker object I created myself.

Looking forward to your feedback,

Lukasz

In 2.5.1, I believe the earlier versions are the same, getDatePicker() returns the actual DatePicker so it should work as advertised.

When you create the DatePicker yourself, how are you creating it?  DateBox uses the no arg constructor...  If you are providing it with a bad model or something like that then it would be at fault not the DateBox or DatePicker.

I'm using 2.5.1 and the DateBox is created via ui:binder. But I also tested it in the simplest possible setting (generating a new GWT projetct with eclipse and creating a DateBox widget in code), where I observed the same strange behaviour.

When you focus a DateBox then the method DateBox.showDatePicker() is called. This method calls datePicker.setCurrentMonth() with the date parsed from the TextBox text or the current date if parsing has failed (e.g. because the TextBox is empty). 

So you either have to call DateBox.setValue() with your month date or you have to extend DateBox and override showDatePicker(), e.g.

public void setMonthSuggestion(Date suggestion) {

  this.currentMonthSuggestion = suggestion;

}

@Override

public void showDatePicker() {

    Date current = parseDate(false);

    if (current == null) {

      current = currentMonthSuggestion; //instead of new Date()

    }

    picker.setCurrentMonth(current);

    popup.showRelativeTo(this);

}

Hi Jens,

this is a really good idea. Thank you for this!
