  Hello -

         1)  I want to  read the text from the widget 
          using XtGetValues but it seems not to work.

/* this is the way I create the Text Widget   */
.....
char buf[100];
.....

  n=0;
  XtSetArg(arg[n], XtNheight, 40);                    n++;
  XtSetArg(arg[n], XtNwidth, 200);                     n++;
  XtSetArg(arg[n], XtNtextOptions,editable);                     n++;
  XtSetArg(arg[n], XtNeditType,XttextEdit);                     n++;
  XtSetArg(arg[n], XtNstring, buf );                    n++;
  w_text = XtCreateManagedWidget("text", asciiStringWidgetClass, form, arg, n);


/*  Here I fetch the text */
void  Accep_text(widget,call_data,client_data)
Widget widget;
caddr_t call_data,client_data;
{                 
  Arg arg[20];
  unsigned int n;
  char buff[100];


  n =0;
  XtSetArg(arg[n], XtNstring,buff) ;                     n++;
  XtGetValues(w_text,arg,n);                     n++;
 }


     ( I've also tried  using  - char * buff - instead of  - buff[100]-,
       but the result was the same : null string).
 
   Do I miss something?.

        2) I decided to use an asciiStringWidget to allow the user to
           edit one line text. The length of the string the user can
           introduce is given by the initial value of XtNstring.Thus
           if you initialize XtNstring to null the user won't be able
           to edit anything.
      ( Maybe dialog widget would be better in this case but I had
       problems with the initialization : length of text field was
       given by label lenght)
      Is it correct?. How can the user be allowed to edit one line 
      without initializing the text?


 Another question:

       I'm using a widget form to implement a menu. Every menu item is
   a command widget. 
      At any moment I want to make insensitive some command widgets.
   I wanted every event that occurs  over these widgets  to be send to the
   form widget. If the mouse button was released over an insensitive menu
   item I wanted to perform an specific  operation. I select button_release
   for the form widgets, but when the button is released over an insensitive
   widget  nothing occurs.


   Thanks in advance for any help!
