Maintaining viewport in TextEditor [message #262956]

Here is what I would like to do inside of a text editor:

ISourceViewer viewer = this.getSourceViewer();
StyledText textWidget = viewer.getTextWidget();
int offset=textWidget.getCaretOffset();
textWidget.setText(text);

textWidget.setCaretOffset(offset);

this does, in fact, put the cursor where it was before.

However, the viewport is scrolled back to the top.

How can I keep it where it was before setting the text ?
