/*******************************************************************************
* DialogF() *
* *
* function to put up modal versions of the XmCreate<type>Dialog functions *
* (where <type> is Error, Information, Prompt, Question, Message, or Warning). *
* The purpose of this routine is to allow a printf-style dialog box to be *
* invoked in-line without giving control back to the main loop. The message *
* string can contain vsprintf specifications. *
* DialogF displays the dialog in application-modal style, blocking the *
* application and keeping the modal dialog as the top window until the user *
* responds. DialogF accepts a variable number of arguments, so the calling *
* routine needs to #include <stdarg.h>. The first button is automatically *
* marked as the default button (activated when the user types Return, *
* surrounded by a special outline), and any button named either Cancel, or *
* Dismiss is marked as the cancel button (activated by the ESC key). Buttons *
* marked Dismiss or Cancel are also triggered by close of dialog via the *
* window close box. If there's no Cancel or Dismiss button, button 1 is *
* invoked when the close box is pressed. *
* *
* Arguments: *
* *
* unsigned dialog_type dialog type (e.g. DF_ERR for error dialog, refer to *
* DialogF.h for dialog type values) *
* Widget parent parent widget ID *
* unsigned n # of buttons to display; if set to 0, use defaults in *
* XmCreate<type>Dialog; value in range 0 to *
* NUM_BUTTONS_SUPPORTED (for prompt dialogs: *
* NUM_BUTTONS_MAXPROMPT) *
* char* title dialog title *
* char* msgstr message string (may contain conversion specifications *
* for vsprintf) *
* char* input_string if dialog type = DF_PROMPT, then: a character string *
* array in which to put the string input by the user. Do *
* NOT include an input_string argument for other dialog *
* types. *
* char* but_lbl button label(s) for buttons requested (if n > 0, one *
* but_lbl argument per button) *
* <anytype> <args> arguments for vsprintf (if any) *
* *
* *
* Returns: *
* *
* button selected by user (i.e. 1, 2, or 3. or 4 for prompt) *
* *
* *
* Examples: *
* *
* but_pressed = DialogF (DF_QUES, toplevel, 3, "Direction?", "up", *
* "down", "other"); *
* but_pressed = DialogF (DF_ERR, toplevel, 1, "You can't do that!", *
* "Acknowledged"); *
* but_pressed = DialogF (DF_PROMPT, toplevel, 0, "New %s", *
* new_sub_category, categories[i]); *
