Qt获取系统信息

Qt获取系统信息

在开发过程中经常会遇到需要知道系统信息的时候，比如：屏幕尺寸、系统版本、语言信息等，本篇文章简单的分享一下我对这些内容的封装

#ifndef STYSTEMINFO_H
#define STYSTEMINFO_H
#include <QRect>
#include <QDesktopWidget>
#include <QApplication>
#include <QScreen>
#include <QDebug>
typedef struct{

    QRect screenRect;
    QRect deskRect;
    int screenCount;

}screenInfo;

class stystemInfo
{
public:
    stystemInfo();
//    static screenInfo GetScreenInfo();
    //获取屏幕宽度
    static int getScreenWidth();
    //获取屏幕高度
    static int getScreenHeight();
    //获取系统版本
    static QString osVersion();
    //获取默认语言
    static QString defaultLangID();
//    static
};

#endif // STYSTEMINFO_H

#include "stysteminfo.h"

stystemInfo::stystemInfo()
{

}

int stystemInfo::getScreenWidth()
{
    QScreen *screen=QGuiApplication::primaryScreen ();
    QRect sRect = screen->availableGeometry() ;

    return sRect.width();

}

int stystemInfo::getScreenHeight()
{
    QScreen *screen=QGuiApplication::primaryScreen ();
    QRect sRect = screen->availableGeometry() ;

    return sRect.height();
}

QString stystemInfo::osVersion()
{
    QString versionInfo;
    versionInfo.append(QSysInfo::productType()).append(QSysInfo::productVersion());
    qDebug() << versionInfo;
    return versionInfo;
}

QString stystemInfo::defaultLangID()
{
   QString language = QLocale::system().name();
//     QString language = QString::fromLocal8Bit("ru_");
     language = language.mid(0,language.indexOf(QChar('_')));
     return language;
}
