Qt QfileSystemWatcher没有';行不通

Qt QfileSystemWatcher没有';行不通,qt,filesystems,filesystemwatcher,Qt,Filesystems,Filesystemwatcher,以下是我初始化监视程序的方式: QFileSystemWatcher watcher; bool isWatched = watcher.addPath("../stylesheets/main.style"); if (isWatched) qDebug() << "Stylesheet is being watched."; connect(&watcher, &QFileSystemWatcher::fileChanged, this, &

以下是我初始化监视程序的方式:

  QFileSystemWatcher watcher;
  bool isWatched = watcher.addPath("../stylesheets/main.style");
  if (isWatched) qDebug() << "Stylesheet is being watched.";
  connect(&watcher, &QFileSystemWatcher::fileChanged, this, &PCLViewer::updateStyle );
updateStyle
函数的签名如下:

public slots:
    void updateStyle(const QString &path);

我正在使用ubuntu。

插槽函数签名错误。我必须使用
voidupdatestyle(qstringpath),以便调用它。

如果有人有相同的问题

试试这个:

QFileSystemWatcher *watcher = new QFileSystemWatcher();
bool beingWatched = watcher->addPath("Enter your path here");
if (beingWatched ) qDebug() << "Being watched";
QObject::connect(watcher, SIGNAL(fileChanged(QString)), this, SLOT(handleFileChanged(QString)));
QFileSystemWatcher*watcher=new QFileSystemWatcher();
bool beingWatched=watcher->addPath(“在此处输入您的路径”);

到目前为止,如果(被监视)qDebug()代码片段看起来是正确的。请发布一个更完整的代码示例。您是否尝试使用文件的完整路径?是的,我厌倦了完整路径和另一个文件,但两者都不起作用!
QFileSystemWatcher *watcher = new QFileSystemWatcher();
bool beingWatched = watcher->addPath("Enter your path here");
if (beingWatched ) qDebug() << "Being watched";
QObject::connect(watcher, SIGNAL(fileChanged(QString)), this, SLOT(handleFileChanged(QString)));
