Except for a couple of glitches during the upgrade process (maybe later more about this), I was able to login to my updated system about an hour later. I opened up Eclipse (running 3.5 – Galileo) to continue my Java development tasks. But very soon I noticed the upgrade introduced severe issues with my favorite IDE, most notably, the buttons on most dialog boxes could not be pushed anymore. Here’s how I managed to fix it ….

The new Ubuntu release 9.10 brings version 2.18 of GTK+ to the desktop. GTK+ is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, the GTK+ is suitable for projects ranging from small one-off tools to complete application suites.  In version 2.18, client side windows are introduced which brings nicer redrawing and resizing, as demonstrated in the video :

Some applications – Eclipse, but also Acroread – assume that they can just operate on the X windows corresponding to their GDK windows without ever telling GDK, which causes some widgets to exhibit weird behaviour. Bug 287307 was filed with the Eclipse foundation and this is fixed for the upcoming 3.6 release.

Fortunately, the GTK+ people provide a switch to turn off the client side windows. So to work around the bug with Eclipse pre-3.6, just make sure you set environment variable GDK_NATIVE_WINDOWS=1

#!/bin/sh
export GDK_NATIVE_WINDOWS=1
/home/koen/eclipse-galileo/eclipse

Start coding :-)
