Hello,

In the application I'm currently developping, I need to access (through setMode and getMode methods), from any classes, to a variable 'mode' that shows in which mode the application is.
I want other classes to be warned about changes of the value of this variables.
That's why I subclasses QApplication.
I cannot though access to this variable, this :

qDebug()<<QApplication_ac::instance()->getMode(); //here, the problem !

give the error :

class QCoreApplication' has no member named 'getMode'
qDebug()<<QApplication_ac::instance()->getMode();


How can I solve my problem ?

Many thanks for answer.

Here is the code :

qapplication_ac.h :

Qt Code: 
  1. #ifndef QAPPLICATION_AC_H
  2. #define QAPPLICATION_AC_H
  3.  
  4. #include <QApplication>
  5.  
  6. enum Mode {NOTHING=0,
  7.            PICKING_DETAIL,
  8.            PANNING,
  9.            ROTATION,
  10.            PICKING_POINT,
  11.            ABOUT_TO_CLOSE,
  12.            POLYGON_FINISHED
  13.           };
  14.  
  15. class QApplication_ac:public QApplication
  16. {
  17.  
  18.       Q_OBJECT
  19.  
  20. public:
  21.     QApplication_ac(int &argc, char *argv[]); //constuctor
  22.     Mode mode;
  23.     Mode getMode(){ return mode;}
  24.     void setMode(Mode modeToSet);
  25.  
  26. signals:
  27.  
  28.     void modeChanged(Mode newMode,Mode oldMode); //other classes will be connected to this signal
  29.  
  30. };
  31.  
  32. #endif // QAPPLICATION_AC_H
