Thomas Anderson of Google has published a preliminary set of patches with the implementation of the ability to use Qt to draw interface elements of the Chromium browser on the Linux platform. The changes are currently marked as not ready for implementation and are at an early stage of review. Prior to this, Chromium on the Linux platform provided support for the GTK library, which is used to display window control buttons and dialog boxes for opening/saving files. The ability to build with Qt will allow for a more uniform Chrome/Chromium interface in KDE and other Qt-based environments.
