Re: Removing a widget from its container without destroying it

[Mickael Drean <mickael drean gmail com>]

When it crash, it wrote:   Gtk-CRITICAL **: gtk_widget_real_realize: assertion 'GTK_WIDGET_NO_WINDOW <widget>' failed

 

some part of my code:

 

class CMyApp

{

  public:

    CMyApp();

    void next();

    void previous();

 

  protected:

    std::list<MyWidget*> m_MyWidget;

    std::list<MyWidget*>::iterator m_Iter;

    Gtk::VBox m_VBox;

};

 

CMyApp::CMyApp()

{

    //some m_MyWidget.push_back(...)

    m_Iter = m_MyWidget.begin();

   m_VBox.add(*(*(m_Iter)));

   add(m_VBox);

 

}

 

CMyApp::previous()

{

    m_VBox.remove(*(*m_Iter));

   m_Iter--;

   m_VBox.add(*(*m_Iter));

}

CMyApp::next()

{

    m_VBox.remove(*(*m_Iter));

   m_Iter++

   m_VBox.add(*(*m_Iter));

}

I'm not sure what you mean by "repertories". but gtkmm 2.6 is version
2.6 of the gtkmm 2.4 API. There is no contradiction.

Try a small test case to show the problem.
