Looking for FOSS projects to read some practical source code..
What I want is to learn from high quality code...but in most of the projects' code ..I'm completely confused by the enormous gui code...(&&many critical portions of the software seem to remain in that portion).
Are there good projects (though it sounds ridiculous ) without much gui code...and somewhat simple to grasp ..(I hope not to look into gnu's or apache source code now !!! ) ..?
OR would it be better to get intimately familiar with GTK, QT ..etc etc...before bothering to try this...?
