一.创建自己的资源文件
你可以从一个xml文件中加载对话框，frame窗口，菜单条，工具条等等。不用c++代码去实现，这符合代码界面和代码分离的原则。
我们可以使用DialogBlocks，XRCed和wxGlade还有wxDesigner工具去绘制我们界面保存在xxx.xrc格式的文件中
二.加载资源文件
要使用rXRC文件，在代码中包含wx/xrc/xmlres.h头文件。如果你打算把XRC文件转化成二进制XRS文件使用。在代码中还有增加zip文件系统函数
你可以在Oninit函数添加如下代码：
#include ”wx/filesys.h”
#include ”wx/fs zip.h”
wxFileSystem::AddHandler(new wxZipFSHandler);初始化XRC系统并加载一个XRC文件 在Oninit函数添加如下代码：
wxXmlResource::Get()−>InitAllHandlers();
wxXmlResource::Get()−>Load(wxT(”resources.xrc”));
三.用wxrc翻译XRC文件加载到代码中：
//例如
wxrc -c -e resource.xrc
//执行这条命令后就会产生resource.cpp resource.h
你也可以完全指定翻译文件和函数例如：
wxrc -c -e -n InitAboutDialog Dlg_About.xrc -o dlg_About.cpp
然后你就可以在Oninit函数中添加这个函数的调用
在Oninit函数文件中添加extern void InitAboutDialog()；
在Oninit函数添加InitAboutDialog();
这2行代码和wxXmlResource::Get()->Load("rc/About.xrc");是等价的。
四.wxrc 参数
五，这里写了个小例子供大家参考
#include "wx/wx.h"
#include "wx/image.h"
#include "wx/xrc/xmlres.h"
//#include "resource.h"
// the application icon
#if defined(__WXGTK__) || defined(__WXMOTIF__) || defined(__WXMAC__)
#include "rc/appicon.xpm"
#endif

// initialization (doing it here and not in the ctor allows to have an error
// return: if OnInit() returns false, the application terminates)
virtual bool OnInit();
};
// Define a new frame type: this is going to be our main frame
class MyFrame : public wxFrame
{
public:

}

void MyFrame::OnQuit(wxCommandEvent& WXUNUSED(event))
{
// true is to force the frame to close
Close(true);
}
void MyFrame::OnAbout(wxCommandEvent& WXUNUSED(event))
{

msg.Printf( _T("This is the about dialog of XML resources demo.\n")
