Question

我想使用wxMediaCtrl为此我制作一个包含

等内容的头文件

#ifndef MEDIA_H_
#define MEDIA_H_
#include <wx/wx.h>
#include <wx/mediactrl.h>
class media: public wxFrame

{

public:

 wxWindow *window;

     media(const wxString& title);

     wxMediaCtrl *media_ctrl;

};


#endif /* MEDIA_H_ */

并使用类似

的代码制作一个cpp文件

#include "media.h"

media::media(const wxString& title)

      :wxFrame(NULL, wxID_ANY, title, wxDefaultPosition, wxSize(600, 600))

{

    window=new wxWindow(this,wxID_ANY,wxPoint(0,0),wxSize(600,600),wxBORDER_SIMPLE,wxT("window"));
    media_ctrl= new wxMediaCtrl(window, wxID_ANY , wxT(""),wxDefaultPosition, wxDefaultSize, 0, wxT(""), wxDefaultValidator, wxT("hello"));}

当我试图运行该页面时，我收到了类似

的错误

任何人都可以告诉我我在哪里犯错误

Answer 1

尝试使用

wx-config --libs std,media

建筑......

Answer 2

要在linux上启用wxMediaCtrl构建wxWidgets（gstreamer 0.10），需要libgconf2-dev和libgstreamer0.10-dev。
