setting min widget size?

[Dan McMahill <mcmahill mtl mit edu>]

Hello,

I have a label widget which is used to show the coordinates of the 
cursor position in a drawing program.  Unfortunately, the width of that 
widget changes as I move the cursor around because the fonts are not 
fixed width fonts and sometimes I have a larger number with more digits 
and sometimes a smaller number.

Is there a way to allow the label widget to grow if needed to hold a 
larger string but then never shrink if the label text is changed to 
something shorter?

Thanks
