Detecting When Help Dialogs Are Dismissed

To detect when a general help dialog is closed, add the following callback to the dialog:

XtAddCallback (helpDialog, DtNcloseCallback,
                HelpCloseCB, (XtPointer)NULL);

Where helpDialog is the widget ID for the help dialog and HelpCloseCB is the name of the callback procedure you've written to handle closing dialogs.

To detect when a quick help dialog is closed, add the following callback to the dialog's OK button:

XtAddCallback (DtHelpQuickDialogGetChild (helpDialog,
 DtHELP_QUICK_OK_BUTTON), XmNactivateCallback, HelpCloseCB, (XtPointer)NULL);

Where helpDialog is the widget ID for the help dialog and HelpCloseCB is the name of the callback procedure you've written to handle closing dialogs.
