打开文档:
QStringLiteral用于兼容中文。
QString fileName(qApp->applicationDirPath() + QStringLiteral("/Help/使用手册.doc"));
if (!QDesktopServices::openUrl(QUrl::fromLocalFile(QFileInfo(fileName).absoluteFilePath())))
{
QMessageBox::information(this, tr("warning"),
tr("Failed to open the help guide."),
QMessageBox::Ok);
}
打开图片:
方式一:
QDesktopServices::openUrl(QUrl(QString("file:///C:/Users/Desktop/image.bmp"));
方式二:
QProcess* process = new QProcess();
QString lastPicPath = logPath;
QString sPicPath = lastPicPath.replace("/", "\\");
QString program = "cmd.exe";
QStringList para;
para << "/c";
//命令间需要添加空格
para << QString("rundll32") + QString(" %Systemroot%\\System32\\shimgvw.dll,ImageView_Fullscreen ")+ sPicPath;
process->start(program, para);
打开文件夹:
openFileExplorer(QString path)
{
QString filepath = path;
//打开资源管理器并高亮文件
const QString explorer = "explorer";
QStringList param;
if (!QFileInfo(filepath).isDir())
param << QLatin1String("/select,");
param << QDir::toNativeSeparators(filepath);
QProcess::startDetached(explorer, param);
}
