Description:
Previously, Qt (11) How to debug with Qt Creator and VC++ Compiler. > In VC + + and Qt Creator combinations, we briefly. This time, Qt Creator MinGw and would like to explain briefly.

This combination, Qt recommended? Qt Creator or rather has become a standard combination. However, Qt Until the 3.5.x, GCC3 system was standard, 3.6.x Until, GCC4 system is now standard. Both, GCC3 system / GCC4 system is supported both, 3.7.x from, GCC3 will be supported out of the system.

Now, here, Windows systems in GCC3 / GCC4 caution when dealing with a system, GCC would like to describe the version strings and source code.

Before you begin, here is work, GZ, 7z to unzip the files must be compressed and, download 7z 7z download from, you should install.

Discription :
I was not writing the article for Qt for a long time. Qt improved the version from 4.5 to 4.7 beta version between those.

So environment had changed.
if you want environment of Qt's development at one years ago, you have needed half a day.But you will get environment of Qt's development very easy by One click for download compiled(VC++ 2008 or MinGW(GCC)) binary files.

I had written the article "What kind of Windows will be able to run Qt application" before. I wrote "What kind of Windows will be able to run Qt application" in the article several months ago. This time, I will write the system requirements for applications of each version of Qt.

Summary:
This time, Qt application is created in which Windows is running a story about you.

This is very simple so that, immediately, I would like to describe briefly.

Summary:
This time, Qt is a story about the QString.
QString is a class action allows a very useful text, QWidget with a string of class inheritance, this former QChar QString QString or do you have in common.

Does, QString is real, what is it?

If you create a Qt application in a closed world of the string, QString if all we Oke, and not a problem anything.
Also, for those who have no plans to create cross-platform applications, you may not matter much.

But for those who otherwise may become very important issue. For example, if another library such as Qt is a library to mix.
At such times, in different library that is what the string you are dealing.
C / C + + type used in general, char, wchar_t may be. STL's string, wstring might. If Windows, MFC's CString might.
QString if the dealing with, you will have a problem.
However, a different type as above, if you are using a class, Qt application to handle the conversion to QString always Tsukimatoimasu.

In such cases, QString and have little understanding of the nature of how we will help in programming.
Does, immediately, I would like to briefly explain.

Summary:
This time, Qt Creator I would like a brief description.
Qt Creator is, Qt SDK is one of, Qt to create an integrated environment for application development (IDE) for that.
Integrated development environment (IDE) is to say, Qt Creator itself, the compiler is not bundled with its own. Using Qt Creator, Windows If you are developing in, MinGw are included by default (if the binary environment).
Linux, Unixes, Mac OS does, gcc is so equipped, the compiler will use it.

In this way, Qt Creator is, gcc was only supposed to work with the system compiler. (For details, VC + + but I was able to compile, debug failed. )
However, in version 1.2 or later, Windows environments, VC + + using the compiler, the execution of the compilation, you can now debugging.

This time, about their preferences, I would like to brief notes.

Summary:
This time, Qt marquee explains the progress bar to show how easily.
and marquee, WindowsXP from the startup screen after the progress bar, rather than to build up, and the show flowing now is to show progress.

This marquee (see propaganda) and the colors that we have referred.
indeterminate (in the effective running I do not know how much), barber-pole (barber's pole), spinning bar (a bar that spins round and round) and so on.
(Web on, barber-pole like a major but, here, marquee Make a uniform. () Is a literal translation in Japanese. I tried to describe what I felt better somehow, I'll understand. )

Came to the Windows API that is compatible with, it is not too old.

This time, Qt uses a sample that is provided in the marquee we'll see.

Description:
This time, Qt for document management, I would like to write.
Document management and to say, Qt software created in the (library) is a document management in the sense of a detailed design.

Software (library) as a document management such as the detailed design, Free in the most famous, doxygen.
Doxygen This was originally created in Qt is designed to manage documents. (I, until recently, did not know that. )

Therefore, doxygen is, Qt is a strong affinity with. (Of course, signals, slots and the right awareness, and then output to the document. )

This time, the use doxygen, I described how to create simple documents.

Description:
In Qt, CppUnit like QTestLib.

In this article, QTestLib Let's create a simple test program.
(This article is part of a tutorial site articles. Qt is the target for the novice programmers. )

Sample source code you used here:

Description:
In Qt, Windows as a change in the HTML Help QtAssistant. (Listed in the article. )
In the previous article, Qt help files (qch files, qhc file) we created.

In this article, Qt help files (qch files, qhc file) describes how to display any interest in the application.
