使用wxWidgets for C++从资源文件中静态装载图像

<? xml version="1.0" ?> 
< resource  version ="2.3.0.1" >    
    < object  class ="wxBitmap"  name ="background" >background.jpg </ object > 
</ resource >

生成的main.h的格式如下：

//
//  This file was automatically generated by wxrc, do not edit by hand.
//

#include <wx/wxprec.h>

#ifdef __BORLANDC__
     #pragma hdrstop
#endif

#include <wx/filesys.h>
#include <wx/fs_mem.h>
#include <wx/xrc/xmlres.h>
#include <wx/xrc/xh_all.h>

    wxXmlResource::Get()->InitAllHandlers();     

wxBitmap background = wxXmlResource::Get()->LoadBitmap(_T("background"));     

m_pStaticBitmap = new wxStaticBitmap(this, wxID_ANY, background, wxPoint(0, 0), wxSize(1024, 768)); 

    m_pStaticBitmap->Refresh();

否则在windows下当窗口缩小后再放大时，图像显示有一些问题。但在linux下可以不加这条语句。
