这是从黑莓10 helloworld程序中提取的头文件.
#ifndef ApplicationUI_HPP_
#define ApplicationUI_HPP_
#include <QObject>
namespace bb
{
namespace cascades
{
class Application;
class LocaleHandler;
}
}
class QTranslator;
/*!
* @brief Application object

*
*/
class ApplicationUI : public QObject
{
Q_OBJECT
public:
ApplicationUI(bb::cascades::Application *app);
virtual ~ApplicationUI() { }
private slots:
void onSystemLanguageChanged();
private:
QTranslator* m_pTranslator;
bb::cascades::LocaleHandler* m_pLocaleHandler;
};
#endif /* ApplicationUI_HPP_ */
在类名声明之后,我对冒号运算符感到困惑.
class ApplicationUI : public QObject
这是什么意思？
