Xfce 4.12 Released
motang writes: After two years of hard work (and much to the dismay of naysayers who worried the project has been abandoned), the Xfce team has announced the release of Xfce 4.12. Highlights include improvements to the window switcher dialog, intelligent hiding of the panel, new wallpaper settings, better multi-monitor support, improved power settings, additions to the file manager, and a revamped task manager. Here is a quick tour, the full changelog, and the download page. I have been running it since Xubuntu 15.04 beta 1 was released two days ago. It is much improved over 4.10, and the new additions are great.
Xfce 4 has been a great desktop environment, but it's now clear that GTK+ is a dead end.
GTK+ is rife with serious problems. The first is that it's affiliated with the GNOME crew. Their grasp of sensible, proper UI design is very suspect, especially after the GNOME 3 disaster. For example, these are the kind of people who took gedit, GNOME's text editor, and changed it from this sensible, usable UI to this hideous, unusable UI. You can even see a screenshot of this shitty UI in the Xfce 4.12 tour! It has, sadly, been infected by this bad UI design.
The portability of GTK+ is, to put it politely, utter rubbish. X11 is the only platform where it isn't a disgrace. It "works" under Windows and OS X, but if by "working" you mean it runs but is generally unusable. I haven't been able to ever get it working properly under OS X. It didn't even get to the point where it showed a UI, the last time I tried it. Inkscape is horrible. GIMP is horrible. Every other GTK+ app I've tried on Windows or OS X has been absolutely horrible.
It will be a lot of work, but they need to port Xfce from GTK+ to Qt. Qt is a much better toolkit. It looks great. It works (and actually works, in that the resulting software is perfectly usable!) pretty much everywhere.
GTK+ had its place in the late 1990s. But we're well past that time now. Qt is the best toolkit to use these days. I truly wish that the Xfce devs would port from GTK+ to Qt, so that we users can use it on Windows and OS X, as well as getting a much better experience under Linux.
Xfce 5 has to be based on Qt.
