爲什麼wxwidgets和sfml不能很好玩？

-1

我想用wxwidgets使用sfml。我試圖按照一個相當過時的教程，因爲沒有更近的教程。爲什麼wxwidgets和sfml不能很好玩？

教程這裏：http://sfml-dev.org/tutorials/1.6/graphics-wxwidgets.php

本教程是sfml1.6和wxWidgets的2.x的，但是我想用sfml2.1與wxWidgets的3但代碼不會編譯。顯然win_gtk.h現在是一個私人頭文件，並且在gtk3中無法訪問？這個頭文件包含gtk_pizza。至於顯示（）錯誤，我不知道有什麼問題...無論如何，使一切發揮不錯？

這裏是我的代碼：

#include <SFML/Graphics.hpp> 

#include <wx/wx.h> 

#ifdef __WXGTK__ 
    #include <gdk/gdkx.h> 
    #include <gtk/gtk.h> 
    // #include <wx/gtk/win_gtk.h> this doesn't exist in wxwidgets3? 
#endif 


class wxSFMLCanvas : public wxControl, public sf::RenderWindow 
{ 
public : 

    wxSFMLCanvas(wxWindow* Parent = NULL, wxWindowID Id = -1, const wxPoint& Position = wxDefaultPosition, 
       const wxSize& Size = wxDefaultSize, long Style = 0); 

    virtual ~wxSFMLCanvas(); 

private : 

    DECLARE_EVENT_TABLE() 

    virtual void OnUpdate(); 

    void OnIdle(wxIdleEvent&); 

    void OnPaint(wxPaintEvent&); 

    void OnEraseBackground(wxEraseEvent&); 
}; 

void wxSFMLCanvas::OnIdle(wxIdleEvent&) 
{ 
    // Send a paint message when the control is idle, to ensure maximum framerate 
    Refresh(); 
} 

void wxSFMLCanvas::OnPaint(wxPaintEvent&) 
{ 
    // Prepare the control to be repainted 
    wxPaintDC Dc(this); 

    // Let the derived class do its specific stuff 
    OnUpdate(); 

    // Display on screen 
    Display(); 
} 


wxSFMLCanvas::wxSFMLCanvas(wxWindow* Parent, wxWindowID Id, const wxPoint& Position, const wxSize& Size, long Style) : 
wxControl(Parent, Id, Position, Size, Style) 
{ 
    #ifdef __WXGTK__ 

     // GTK implementation requires to go deeper to find the 
     // low-level X11 identifier of the widget 
     gtk_widget_realize(m_wxwindow); 
     gtk_widget_set_double_buffered(m_wxwindow, false); 
     GdkWindow* Win = GTK_PIZZA(m_wxwindow)->bin_window; 
     XFlush(GDK_WINDOW_XDISPLAY(Win)); 
     //sf::RenderWindow::Create(GDK_WINDOW_XWINDOW(Win)); 

    #else 

     // Tested under Windows XP only (should work with X11 
     // and other Windows versions - no idea about MacOS) 
     //sf::RenderWindow::Create(GetHandle()); 

    #endif 
}

下面是錯誤：

這是因爲您試圖將其作爲鏈接發佈。把錯誤和你的代碼直接放在你的帖子中。 – 2014-09-02 18:43:51

@ user1953923在詢問之前，請檢查此[標記幫助部分]（http://stackoverflow.com/editing-help#code），還請[參觀]（http://stackoverflow.com/tour）！ – 2014-09-02 18:49:50

本教程的確是過時的，這是從來沒有使用私人wxGTK頭和實施細則中是個好主意任何情況。我對SFML一無所知，但您需要了解其文檔中描述的原生WindowHandle究竟是什麼，然後您應該能夠從wxGTK中獲得它。

FYI m_wxwindow是GtkFixed這本身就是一個GtkContainer這是一個GtkWidget，所以如果你能找出如何使用SFML與本地GtkContainer或GtkWidget，你應該能夠與wxGTK使用它，以及沒有太多的問題。

祝你好運！
