Hello, I have a browser that displays a list of key / value pairs. The values 
change quite fast but not all the values change on each update cycle. Currently 
I refresh the list by calling browser->clear() and then adding the pairs back 
to the list with the new values. For large lists this causes interference with 
the timing of our code. Is there a way to update only certain items on the list?

My understanding of the way fltk uses char buffers is that fltk does not keep 
copies of the string buffers itself. If I pass a char array to the add() 
function, shouldn't changing the char array reflect on the browser entries?

Thanks.
