Problem with DateTime in Java

i have used the Swt DateTime. But I get the problem that we cannot send null value through it. it is always declared. So i used the nebulla dateChooserCombo. it's a good one and i can send the null value too. But I faced the problem that unlike the Swt DateTime It is really difficult to switch form one year to another.we have to move everymonth in it. We can explicitly enter the date through th开发者_如何学Goe DateChoosercombo but user may not know the date Pattern so it may be difficult for them. Is there any solution for this Problem.Please Do suggest me? is There any way we can enter Null value through swt DateTime?

Then you can add checkbox which will enable or disable the DateTime widget, and let user to decide if he/she wants to define the date or not..

but user may not know the date Pattern so it may be difficult for them

So tell them the pattern (e.g. in a Label or in the tooltip for DateChooserCombo).

is There any way we can enter Null value through swt DateTime?

No.
