Accessing the Eclipse source code

admin — Sun, 07 Nov 2010 18:24:29 +0000

Sometimes I really want to know how Eclipse implements one feature or another, because Eclipse sometimes feels like magic. Usually it turns out they are also just cooking with water.

Most open source code is easily available by checking out a project from some SCM. For eclipse it is not as easy. But there is a nice tutorial how to access eclipse source code by Lars Vogel. This post is just so I can recover the link next time instead of googling for an hour. Thanks, Lars!

Eclipse 3.5.1 mouse event problems with gtk >= 2.18

admin — Mon, 25 Jan 2010 11:59:24 +0000

Recently, Eclipse started ignoring clicks on dialog buttons for me. This seems to be due to some changes in gtk 2.18. It does not use native windows for all widgets anymore, and SWT seems to rely on it.

Thanks to this blog post, I have this fix in my bashrc:

alias eclipse="GDK_NATIVE_WINDOWS=true eclipse"

The Debian bug tracker also knows about this problem, which is partly fixed for the eclipse packages. Bad luck that I am using a download from eclipse.org.

Enforcing the aspect ratio of a Swing widget

Sometimes, a widget only looks good at a given aspect ratio (movies, pictures, etc.).

I wrote a small Swing container for this task today, which you can find at my trac installation. There is also a small example program.

Usage boils down to using

parent.add(new AspectRatioContainer(4.0/3.0, widget)).

instead of just

parent.add(widget);

Perhaps this is of use to somebody.
