It’s easy to make your programs more effective for your users.

And when it comes to GUI applications, there’s a world of difference between a working interface and one that’s both useful and effective. Selecting the right tool for the right job is a skill that comes with experience, and the best way to get that experience is to use the tools available to you. In this chapter, you’ll continue to expand your GUI application building skills. There’s a bunch of truly useful widgets waiting to be experienced. So, turn the page and let’s get going.

Time to mix it up

Your best friend is an ultra hip DJ with a problem: his vinyl collection is now so large that he can’t carry it all around from club to club anymore. He’s decided to digitize his entire collection, put it on his laptop, and mix his sounds from there. His problem is that commercial mixing software costs a fortune and he doesn’t like any of the free alternatives. He has his own ideas for the mixing software he wants.

What with spending all his time mixing music, he’s never learned how to program his computer... and that’s where you come in. If you help him to write the software he needs, he promises to showcase your work at the upcoming World Music Mixing Expo.

Let’s build the mixing software bit-by-bit based on the DJ’s requirements.
