  • How to slove the problem of Garbage Characters of Chinese and Errors of Images in Qt

    Sometimes it is miserable to find that the release version of your software has Garbage Characters and Errors in Images.

    Here is a good solution which has been tested to be ok.

    1. In the main() function of your program, add this at the very beginning:

        QApplication::addLibraryPath("./plugins");
    

     If it were not added at the very beginning of the program, the following program would not be able to find the plugins needed.

    2. Create a new folder in the release folder named "plugins" which will be used to hold the plugins that we need.

    3. Go to the directory where your Qt is installed. Find the plugins folder.

    Mine is "D:\QtSDK\Desktop\Qt\4.7.4\mingw\plugins"

    4. Now you can see several folders: accessible, bearer, codecs, designer, graphicssystems, ...

    5. Copy the folder of codecs and imageformats to the folder that we created before.

    We have to copy the folder with all files.

    If we just copies all the files but the folder that hold it, it will not work.

    6. Set fonts in the code:

        QTextCodec *codec = QTextCodec::codecForName("GB2312");
        QTextCodec::setCodecForLocale(codec);
        QTextCodec::setCodecForCStrings(codec);
        QTextCodec::setCodecForTr(codec);
    

     7. Now you can use Chinese and Imagines with no trouble!
