In this part of our series we’ll dive in and start implementing our logic from the command line application to the GUI version.
The goal during this step is to make exclusive use of the Qt frameworks built-in functions and methods for handling these tasks, as the end result must be a cross-platform compatible app.
We’re already getting a valid directory entry from part 2, so the first step in this part is to figure out how we iterate and query files from our base folder.
In this post I want to introduce the Qt code I’ve written so far. One of the strengths of the Qt framework is its well supported in NetBeans, but more importantly, by Nokia via the Qt Creator IDE. In fact, Nokia supplies a host of tools, from the IDE and language tools, an Interface Designer, and loads of examples.
At the end of this post we’ll have a shell ready for the actual porting process to being. In other words, a GUI that loads, reacts to button presses, and updates status text.
In this post we’ll start the process of porting a simple command line C++ application to the Nokia Qt framework. Well take a quick look at the code in question, then talk about how we’ll port it.
The application in question is a simple tool for cleaning up the export of a Print Publishing CMS system for eventual use in a Web-based CMS. By simple I mean we open a folder and loop through it, diving into sub-folders as needed to:
The application started as an Apple Xcode project, and has now moved into NetBeans 6.8 on Linux. In the end I hope to learn a good deal about the Qt framework, as well as proper C++ application development.
The strange thing about this post is that this isn’t exactly news–ever since FireFox 3.5 came out in June of ’09, and along with Safari 4 and Google Chrome using a slightly different mechanism, these browsers all support OS Level multi-threading.
The question is, should you care?
It’s sometimes hard to find a good example of working with threads in C++. Thus, in the course of implementing a very simple working example I decided it wouldn’t hurt to post what I came up with.
