Source-highlight-qt is a library for performing syntax highlighting in Qt documents by relying on the GNU Source-Highlight library. It provides an implementation of the Qt abstract class QSyntaxHighlighter class, and it deals both with Qt3 and Qt4, although you will need to build a separate version of the library for the two different Qt framework versions. The Qt3 version has fewer features and it is there only for old Qt applications. Furthermore, the QSyntaxHighlighter class in Qt3 has some design problems which make it quite inefficient to use.
GPlates offers a novel combination of interactive plate-tectonic reconstructions, geographic information system (GIS) functionality, and raster data visualization. GPlates enables both the visualization and the manipulation of plate-tectonic reconstructions and associated geological, geophysical, and paleo-geographic data through geological time.
