XtSetValues is used to set some initial operating parameters:
XtSetValues $FORM \ initialFocus:$SD \ defaultButton:$OK \ cancelButton:$CLOSE \ navigationType:EXCLUSIVE_TAB_GROUP
Initial focus is set to the first TextField widget in the first area.
Default button is set to the OK push button in the fourth area.
Cancel button is set to the Close button in the fourth area.
Navigation type is set to EXCLUSIVE_TAB_GROUP.
The following line configures the TextField widgets so that pressing the return key does not activate the default button within the Form. See the description of EXCLUSIVE_TAB_GROUP in Appendix B for more information on its use.
