AutoScroll text to bottom of a StyledText component in SWT

[ragz wifer]

Hi,

I'm reading a text file and displaying in the styledtext component of SWT, each time a new line is appended it's not shown, i mean the line is added to the next row but the scrollbar is NOT scrolling to the next row.
How can i make it auto scroll, as a workaround i tried using

styledText.selectAll();

it does auto scroll,but shows the complete selection of text, can someone provide an optimal and better programming practice for this case.
