Someone asked how to get text from a buffer in the TextWidget.

The following worked for us.

-------------------------------------------------------------------------------
/*

   so feel free to use it however you wish!
*/
#include <X11/TextP.h>

...

char *GetTextFromScreen (w)

Widget w;
{
   static XtTextBlock tb;
   TextWidget ww = (TextWidget) w;

   (*ww->text.source->Read)
      (ww->text.source, 0l, &tb, 2000);
  return tb.ptr;
}
-------------------------------------------------------------------------------

Note that it accesses private widget data and requires the private
header file.

We tried using the corresponding text replacement routines to write
to the text widget, but only got the 1st 2 characters to show up;
the rest of the widget was blanked out.

This was under X11R2 - by  the time R3 was up, we had written a
replacement for the TextWidget (VERY limited functionality compared
to the TW - don't think I threw together a true replacement!), so
I don't know whether the text replacement would work under R3 or
not. We never got it to work.

We use the default buffer allocated by the TW.
