错误：'qtmobility'不是命名空间名称

Question

我正在尝试编译： http://wiki.forum.nokia.com/index.php / fetching_a_map_tile_in_qt_using_google_maps

我正在使用qt-mobility 1.2，qt 4.7 on opensuse 11.2

我收到的错误是：

MainWindow.h:7: error: ‘QtMobility’ is not a namespace-name
MainWindow.h:7: error: expected namespace-name before ‘;’ token
MainWindow.h:10: error: expected class-name before ‘{’ token
In file included from /opt/qtsdk-2010.05/qt/include/QtCore/qcoreapplication.h:47,
                 from /opt/qtsdk-2010.05/qt/include/QtGui/qapplication.h:45,
                 from /opt/qtsdk-2010.05/qt/include/QtGui/QApplication:1,
                 from main.cpp:2:
/opt/qtsdk-2010.05/qt/include/QtCore/qeventloop.h:51: error: expected initializer before ‘QtCoreModule’
make: *** [main.o] Error 1

.

我的.pro文件包含：

TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .

HEADERS += MainWindow.h
SOURCES += main.cpp MainWindow.cpp

QT += network
CONFIG += mobility
MOBILITY = location

.

错误在标题文件中报告，我如下所示：

#include <QtNetwork/QNetworkAccessManager>
#include <QtNetwork/QNetworkReply>
#include <QPaintEvent>
#include <QPixmap>

using namespace QtMobility;

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow ();
    void paintEvent(QPaintEvent* paintEvent);

public slots:
    void handleNetworkData(QNetworkReply* reply);

private:
    void fetchMap(const QSize& size, qreal latitude, qreal longitude);

private:
    QNetworkAccessManager networkAccessManager;
    QPixmap mapPixmap;
}

.

请指南。

Answer 1

You'll need to include at least one QtMobility header to be able to use that namespace.

Also that using namespace declaration is not the recommended way anymore. Use:

 QTM_USE_NAMESPACE

instead (see QtMobility QuickStart).
