This calendar UI control can be used anywhere in the Java UI. In the above picture, an instance of the AtCalendar is added inside a JFrame to construct the view. You can create instances from AtCalendar and show to the user as a component in a window, a popup, or as a embedded child component in a container.
Here is another example about how the AtCalendar can be used to a Java GUI application. The start and end dates can be changed by selecting a new date and time from the popup AtCalendar. Clicking on the right hand side icons on the Start/End field shows the AtCalendar as a popup.
