Note, you need to get a fresh reference to the display picture
after each time you resize the FTC. The reason for this is the FTC
needs to resize the internal display to fit the new size of the
control. If don't get a new reference, you will be using a picture
that the FTC isn't using any more.

To set the width, this depends on the mode you want to set the FTC
in. From your previous descriptions of what you were trying to do,
I will assume you want to put the FTC in edit mode. So once you
set the FTC in edit mode, you can set the control's width
directly. I have modified your original code slightly because you
want to change the control's width and not the window's size.

me.TextField.getDoc.setXML( xmlData )
me.TextField.Width = maxWidth
me.TextField.resize

At this point, the display is the right width and the text has
been composed. Next we need to get the height. (Note, I am mixing
in some pseudo code here.)

p =  
me.TextField.getDoc.getParagraph(me.TextField.getDoc.getParagraphCount  
- 1)
height = p.getProxyItem(0).getComposePosition + p.getHeight(true) +  
bottom margin height

Basically what we are doing is going to the last paragraph and
getting its rendering position. Note, I have not tested this code
out, so there is a chance it may not work because I can't remember
if the composition position is calculated if it is not visible. I
am pretty sure it does, but if not then don't worry because there
are other ways to calculate this.

Now you can take the height and plug it back into the control's
height.

me.TextField.height = height
me.TextField.resize

Now you are ready to get the display picture.

Tell me how this works.
