本文介绍了一个使用wxStandardPaths类来获取不同系统路径的C++示例代码，包括应用程序文档目录、数据目录等，并展示了如何通过这些路径进行文件操作。

场景:

1.wxStandardPaths 用来获取各种系统路径，可以用于存放app的配置数据。比如文档目录,appData等。

代码:

#include "wx/wxprec.h"

#ifndef WX_PRECOMP
    #include "wx/wx.h"
#endif

#include "wx/cmdline.h"
#include "wx/app.h" 
#include <assert.h>
#include <iostream>
#include <stdio.h>
#include "wx/stdpaths.h"
#include <Windows.h>
#include <shlobj.h>

using namespace std;

void TestStandardPaths()
{
	cout << "TestStandardPaths" << endl;
	wxStandardPaths& sp = wxStandardPaths::Get();
	cout << "GetAppDocumentsDir (): " << sp.GetAppDocumentsDir() << endl;
	cout << "GetDataDir (): " << sp.GetDataDir() << endl;
	cout << "GetDocumentsDir (): " << sp.GetDocumentsDir() << endl;
	cout << "GetExecutablePath  (): " << sp.GetExecutablePath() << endl;
	
	cout << "GetLocalDataDir(): " << sp.GetLocalDataDir() << endl;
	cout << "GetPluginsDir(): " << sp.GetPluginsDir() << endl;
	cout << "GetResourcesDir(): " << sp.GetResourcesDir() << endl;
	cout << "GetTempDir(): " << sp.GetTempDir() << endl;
	cout << "GetUserDataDir(): " << sp.GetUserDataDir() << endl;
	cout << "MSWGetShellDir(): " << sp.MSWGetShellDir(CSIDL_APPDATA) << endl;
}

int main(int argc,char* argv[])
{
	wxInitialize();
	wxEntryStart(argc,argv);
	wxInitAllImageHandlers();

	TestStandardPaths();
	wxEntryCleanup();
	wxUninitialize();
	return 0;
}

输出:
