Class ConnectDialog

java.lang.Object
  org.eclipse.jface.window.Window
      org.eclipse.jface.dialogs.Dialog
          org.fosstrak.llrp.commander.dialogs.ConnectDialog

All Implemented Interfaces:

org.eclipse.jface.window.IShellProvider

Direct Known Subclasses:

AddFCDialog, AddReaderDialog

public abstract class ConnectDialog
extends org.eclipse.jface.dialogs.Dialog

superclass for all the connect dialogs. all subclasses have to instantiate the two members FIELDS and DEFAULTS as arrays providing the labels and the default values for the fields available.

FIELDS = new String[]{ "test", "me" };
DEFAULTS = new String [] { "myTestDefault", "memuuDefault" };
will create two fields with labels "test" and "me" with the respective default values.
