findParentFrame

public static java.awt.Frame findParentFrame(java.awt.Component component)

A handy method to find the first ancestor of "component" which is a Frame.

getDateFrom

public static java.util.Date getDateFrom(javax.swing.JTextField tf)

Use a simple JTextField to get/set date values. This is useable wherever a JCDateTextField is inconvenient. If there is no text or if the text cannot be parsed to a date, return null.
