Using DirectoryWatcher

[skegg]

I want to use class Poco::DirectoryWatcher to receive notifications about new files appearing in a directory. I create DirectoryWatcher object

Code: Select all

DirectoryWatcher dw (string ("dir"));

Then I have a problem adding a delagate to event itemAdded. I want to use a method onAdd of the object listener, that instantiates class Controller

Code: Select all

class Controller {
  public:
  void onAdd (const void*, DirectoryWatcher::DirectoryEvent&) {
      cout << "Event" << endl;
  }
};

.....

Controller listener;
dw.itemAdde += delegate (&listener, &Controller::onAdd);


And here I receive compilation error. What do I do wrong and what and how must I do?

All required headers were included.

Poco library 1.45, Xubuntu 12.04, gcc 4.6.

Thanks.

Thanks. I have already found the error myself. But your code helped me to learn some features of Poco I had not known.
