Examples of org.eclipse.jface.viewers.StyledString

org.eclipse.jface.viewers.StyledString
A mutable string with styled ranges. All ranges mark substrings of the string and do not overlap. Styles are applied using instances of {@link Styler} tocompute the result of {@link #getStyleRanges()}. The styled string can be built in the following two ways:
- new strings with stylers can be appended
- stylers can by applied to ranges of the existing string
This class may be instantiated; it is not intended to be subclassed.
