The LXDE developers are working on a Qt-based version of their desktop and have already ported significant parts of the components of LXDE to the user interface framework. While still in an experimental state, the developers could already show a functional desktop with the panel, PCManFM file manager and an image viewer in a working state. Most of the desktop's applets work with the ported panel as well.
The developers say that they have not stopped development on the GTK+ 2 version of LXDE and that the Qt version is currently a side project. Being faced with an eventual transition from GTK+ 2, which is no longer being developed in the upstream project, to GTK+ 3, it seems the project is hedging its bets with the Qt port. According to the developers, resource usage of the Qt port is comparable with that of a potential GTK+ 3 port and only manifests a "mild elevation of memory usage" over the current GTK+ 2 based version.
