Open source libraries

The following instructions assume that the QuaZIP library is imported into the same workspace as your project.

1. Download QuaZIP from GitHub .
2. Import the project into your workspace. Select Copy Into when importing.
3. Update your application's .pro file to include the following:

INCLUDEPATH += ../src ../../quazip/src/
LIBS += -lbbsystem
LIBS += -lbbdata
LIBS += -lz

lupdate_inclusion {
    SOURCES += ../assets/*.qml
}

device {
    CONFIG(release, debug|release) {
        DESTDIR = o.le-v7
        LIBS += -Bstatic -L../../quazip/arm/o.le-v7 -lquazip -Bd
        ynamic
    }

    CONFIG(debug, debug|release) {
        DESTDIR = o.le-v7-g
        LIBS += -Bstatic -L../../quazip/arm/o.le-v7-g -lquazip 
        -Bdynamic 
    }
}

simulator {
    CONFIG(release, debug|release) {
        DESTDIR = o
        LIBS += -Bstatic -L../../quazip/x86/o-g/ -lquazip -Bdyna
        mic 
    }

    CONFIG(debug, debug|release) {
        DESTDIR = o-g
        LIBS += -Bstatic -L../../quazip/x86/o-g/ -lquazip -Bdyna
        mic
    }
}

The following sample demonstrates using QuaZIP to extract a .zip file to the shared downloads directory. The sample requires the Shared Files permission in order to write to the downloads directory. The sample also requires you to use the following import statement: #include "../quazip/src/quazipfile.h"

bool ApplicationUI::extractArchive(QString m_filename) {
// check if file exists

QFile file(m_filename);
if (!file.exists()){
    qDebug() << "File does not exist.";
    return false;
}

bool result = true;
QuaZip *m_zip = new QuaZip(m_filename);

QString dataFolder = QDir::currentPath();
QString bookname = m_filename.split("/").last().split(".").first();

QString dest = dataFolder + "/shared/downloads/" + bookname;
QDir dir(dest);
if (!dir.exists()) {
    dir.mkpath(".");
}

qDebug() << "destination folder: " + dest;

m_zip->open(QuaZip::mdUnzip);

if (!m_zip) {
    return false;
}

QuaZipFile *currentFile = new QuaZipFile(m_zip);
int entries = m_zip->getEntriesCount();
int current = 0;

for (bool more = m_zip->goToFirstFile(); more; more = 
        m_zip->goToNextFile()) {
    ++current;
    // if the entry is a path ignore it. Path existence is ensured 
    separately.
    if (m_zip->getCurrentFileName().split("/").last() == "")
        continue;

    QString outfilename = dest + "/" + m_zip->getCurrentFileName();
    QFile outputFile(outfilename);
    // make sure the output path exists
    if (!QDir().mkpath(QFileInfo(outfilename).absolutePath())) {
        result = false;
        qDebug() << "[ZipUtil] creating output path failed for:" 
                << outfilename;
        break;
    }
    
    if (!outputFile.open(QFile::WriteOnly)) {
        result = false;
        qDebug() << "[ZipUtil] creating output file failed:" 
                << outfilename;
        break;
    }
    
    currentFile->open(QIODevice::ReadOnly);
    outputFile.write(currentFile->readAll());
    if (currentFile->getZipError() != UNZ_OK) {
        result = false;
        //emit logItem(tr("Error during Zip operation"), LOGERROR);
        qDebug() << "[ZipUtil] QuaZip error:" 
                << currentFile->getZipError() 
                << "on file" << currentFile->getFileName();
        break;
    }
    currentFile->close();
    outputFile.close();
    }

return result;
