The classes from package icsbep.graph.sgt.util are subclasses of Dialog. Several methods commonly appear in these subclasses. These methods are:

• buttonApply_Clicked is invoked when the user clicks on the "Apply" button. This method invokes method updateXXXX where XXXX denotes an attribute, such as updateLineAttr.
• buttonCancel_Clicked is invoked when the user clicks on the "Cancel" button. This method cancels the operation and exits the dialog box.
• buttonOK_Clicked is invoked when the user clicks on the "OK" button. This method invokes method updateXXXX where XXXX denotes an attribute, such as updateLineAttr. The method then closes the dialog box.
