So I'm trying to have my slot emit a signal but I am getting the error " C2065 emit undeclared identifier." I think I have all the includes I need. I'm probably just doing something stupid, here is my code:

Qt Code: 
  1. class MyWidget : public QWidget
  2. {
  3.   Q_OBJECT
  4. .....
  5.  
  6.  Q_SIGNALS:
  7.     void validFile();
  8.  
  9.   public Q_SLOTS:
  10.     void enterFile();
  11.     void getDates();   
  12.     void slotButtonLoads();
  13. };
  14.  
  15. MyWidget::MyWidget(QWidget * parent):QWidget(parent){
  16. ...
  17.  push = new QPushButton("Plot", this);
  18. connect(push, SIGNAL(clicked()), this, SLOT(enterFile())); 
  19. connect(push, SIGNAL(validFile()),this, SLOT(getDates()));   ///also I don't know what my sender should be for this new signal, 'push' is probably not right
  20. }
  21.  
  22. void MyWidget::enterFile()
  23. {
  24.     QString textEntered = lineedit->text();
  25.     FileName = qstrdup( textEntered.toLatin1() );
  26.     if (fopen (FileName, "rb") == NULL){
  27.       emit validFile();
  28.     }else{ 
  29.           //something          }  //// a third question.. how can I allow the user to try again with the filename. I don't think I should
  30.                                           ////// push->disconnect() because it will break my connection
  31. }
To copy to clipboard, switch view to plain text mode 

Thanks for all the help
