When starting learning Glade, it is essential to learn the basic concepts of GTK+. Unfortunately there is a misconception that it’s enough to learn Glade for learning GUI designing rather than learning GTK+. Glade is definitely an easier way to implement GTK but it is impossible to create interface for your application with only Glade knowledge.

For the last couple of ubuntu versions, gnome-screensaver, which is also the gnome screen-locking program, has been using gtkbuilder .ui files for configuration; unfortunately almost all of the third-party themes (e.g. on gnome-look.org) use .glade files. Here's how to convert a .glade file to a .ui file for use with current versions of gnome-screensaver:

Qt 4.7 has not been released yet, but the curious can download the beta or even grab a snapshot from git. The big news in this point seven release is Qt Quick - a new approach to user interfaces. Before I get carried away and start throwing screenshots at you, let's step back and look at today's user interfaces.

ZK is an AJAX toolkit designed to make creating user interfaces that run in a Web browser as simple as creating event-driven interfaces for desktop applications. The interfaces created with ZK use an XML markup language to define the user interface and Java code to implement the Web application's functionality.

Released just a few days ago, GNOME 3 is the latest major version of the GNOME desktop environment. If you are currently running a GNOME-based Linux or BSD distribution, you are probably using version 2.30 or 2.32, but that should change in the upcoming release cycle when many of the distributions will be shipping with GNOME 3 as the default.

The licensing of the Qt toolkit has perhaps been one of the great sagas of the Open Source world. It was Qt's proprietary license — and KDE's reliance on Qt — that led to the creation of the GTK-based GNOME Desktop Environment in 1997.

Nokia has released beta versions of Qt 4.7 and Qt Creator 2.0. The highlight of the new development line is Qt Quick, a tool collection for creating animated, touch-enabled Qt interfaces

Gmount-iso is a small tool written using PyGTK and Glade. It allows you to easily mount your cd images. This is a frontend to the ‘mount -o loop -t iso9660 foo.iso /mountpoint‘ command…Convert your CDs and unprotected DVDs into “virtual CDs"

See what's new with Java and the Google Web Toolkit and build a desktop-like Web application. Google Web Toolkit (GWT) lets you use the Java language to implement rich client user interfaces that run in a browser. This article brings you up to speed on the latest version of GWT and shows you how to build desktop-like Web apps with the GWT and Java code.
