Say I want to implement an utility dialog, InputDialog in DFL which is a subclass of Form,using its static method I can call InputDialog.getString to retrieve a string from the textbox of this dialog  other than create an instance of InputDialog,at the mean time I want to customize the caption text and the prompt message of the InputDialog in the static method InputDialog.getString.But I can't modify Form.text, (form.)TextBox.text  in the static method.Currently I have to  use its non-static version of getString method and create an instance of the dialog each time when I call getString.
