I am trying to create an application containing a StyledText window displayed in ScrolledComposite. I'm having difficulty displaying a large number of lines in my StyledText block (over 2,550 seem to cause problems).
The StyledText field should not have a scrollbar, but it should scroll through a ScrolledComposite. Since there are other elements below and above StyledText that need to be scrolled, and I don't need a few scroll bars.
Therefore, with large amounts of data, I have a very large (as in height) StyledText window, which seems to stop after a certain height.
