I h  ave been trying to figure this out for days, without sucess.
I have a program that was written for X11R3 and used the folloing code:
ForceBuildLineTable(ipanel->text) where

ipanel->text = XtCreateManagedWidget("IPANEL",asciiStringWidgetClass,
                                       box, a, XtNumber(a));

I am trying to replace the X11R3 function ForceBuildLineTable with the X11R4
function _XawBuildLineTable. _XawBuildLineTable takes the arguments

	_XawTextBuildLineTable (ctx, position, force_rebuild)
	TextWidget ctx;
	XawTextPosition position;       /* top. */
	Boolean force_rebuild;

The code for old ForceBuildLineTable() in ites entirety is


	void ForceBuildLineTable(ctx)
	    TextWidget ctx;
	{
  	  XtTextPosition position;

	    position = ctx->text.lt.top;
	    ctx->text.lt.top++; /* ugly, but it works */
	    BuildLineTable(ctx, position);
	}


So, to use the new function, I have to provide the parameter position, and get it
 from the TextWidget ipanal->text. I have been unable to access the elements of 
TextWidget. Basicly, I cannot figure out what the elements of a TextWidget are,
and can therefore only guess what my indirect references should be. 
I have tried :
_XawTextBuildLineTable(ip->text,
                         ip->text->lt.top,
                         TRUE);
But my compiler only snorts at me in contempt.

Help!!!!
