Having some QObject problems

[spirit]

oh, I didn't notice that

class MainWindow : public QTableWidget

class MainWindow : public QTableWidget

To copy to clipboard, switch view to plain text mode 

if want to use QToolBar and other features which provide QMainWindow then you must derive your class from QMainWindow, i.e.

class MainWindow : public QMainWindow

class MainWindow : public QMainWindow

To copy to clipboard, switch view to plain text mode

make a separate class for table widget, and set it as central widget of main window
