How to add a Date and Time popup to smartGWT

There are a lot of queries about how to add a popup for selecting time and date in smartGWT. The bottom line is that smartGWT is lacking a single widget to do this, so you have to use a DateItem and TimeItem together.

Here is some sample code that adds these items to a VLayout call leftPanel:

 final DynamicForm scheduleForm = new DynamicForm();
 DateItem sendDate  = new DateItem();
 TimeItem sendTime = new TimeItem();
       
 scheduleForm.setFields(sendDate,sendTime);
 leftPanel.addMember(scheduleForm);
