[SOLVED][C++/Qt] Unknown custom slot - undefined reference to

Hey all !

I'm learning Qt and I wanted to train and get something useful in the same time. So I decided to make an application that tells me, via a system beep, when a new announce is available in a french web site, and sort them by specific criteria.

I've actually already written it in bash, and it works pretty well. I'm trying to adapt it so I get an interface with Qt. Though I'm having an issue : my custom slot is unknown.

You can get the archive here.

Or the pastbin links :

main.cpp : http://pastebin.archlinux.fr/412193
MainWindow.h : http://pastebin.archlinux.fr/412194
MainWindow.cpp : http://pastebin.archlinux.fr/412195

Compilation gives me this :

[sebastian@arch-pc LeBonCoinChecker]$ qmake -project
[sebastian@arch-pc LeBonCoinChecker]$ qmake
[sebastian@arch-pc LeBonCoinChecker]$ make

Thanks for reading,

MainWindow.cpp says "void s_apply" rather than "void MainWindow::s_apply" on line 85.
