  • Method Details

    • connect

      public final QMetaObject.Connection connect​(Object receiver, String method, Qt.ConnectionType... type)
      Connects the signal to a method in an object. Whenever it is emitted, the method will be invoked on the given object.
      Parameters:
      receiver - The object that owns the method
      method - The signature of the method excluding return type and argument names, such as "setText(String)".
      connectionType - One of the connection types defined in the Qt interface.
      Throws:
      QNoSuchSlotException - Raised if the method passed in the slot object was not found
      RuntimeException - Raised if the signal object could not be successfully introspected or if the signatures of the signal and slot are incompatible.

    • disconnect

      public final boolean disconnect​(Object receiver, String method)
      Disconnects the signal from a method in an object if the two were previously connected by a call to connect.
      Parameters:
      receiver - The object to which the signal is connected
      method - The method in the receiver object to which the signal is connected
      Returns:
      true if the connection was successfully removed, otherwise false. The method will return false if the connection has not been previously established by a call to connect.
      Throws:
      QNoSuchSlotException - Raised if the method passed in the slot object was not found

    • disconnect

      public final boolean disconnect​(Object receiver)
      Removes any connection from this signal to the specified receiving object
      Parameters:
      receiver - The object to which the signal has connections
      Returns:
      true if any connection was successfully removed, otherwise false. The method will return false if no connection has previously been establish to the receiver.

    • disconnect

      public final boolean disconnect​(QMetaObject.Connection connection)
      Removes the given connection from this signal.
      Parameters:
      connection - the connection to be removed
      Returns:
      true if the disconnection was successful.
