[Qt-interest] problem on showing the dll gui inherited from qwidget

[hakiim the dream]

Hi, I am implementing a gui inherited from qwidget, as a dll. And below is class definition of my gui class.class __declspec(dllexport) myGui : public QWidget, public myInterface{ 	Q_OBJECT public:  myGui(QWidget *parent = 0, Qt::WFlags flags = 0);  ~myGui ();  void run();  private: //.... }The window modality property of the gui is set to Qt::WindowModal.
The gui class is also implementing a virtual function called run(), which is defined in the interface class.To show the gui dll in the caller side, I call show() inside the run implementation.The gui dll raises a debug error with the title ASSERT failure in QVector<T>::at: "index out of range", file c:\iwmake\build_vs2008_opensource_____padding_____\include\qtcore....I also tried setVisible(true) istead of show(), but it raised the same error.Any solutions to the problem?
