wxWidgets中的命令行参数

问题描述

有没有办法我可以读取传递到C ++ wxWidgets应用程序的命令行参数？

Is there a way I can read the command line arguments passed into a C++ wxWidgets application? If so, could you please provide an example of how to do so.

推荐答案

请查看这些示例（，）或：

Have a look at these examples (1, 2) or:

int main(int argc, char **argv)
{
    wxApp::CheckBuildOptions(WX_BUILD_OPTIONS_SIGNATURE, "program");

    wxInitializer initializer;
    if (!initializer)
    {
        fprintf(stderr, "Failed to initialize the wxWidgets library, aborting.");
        return -1;
    }

    static const wxCmdLineEntryDesc cmdLineDesc[] =
    {
        { wxCMD_LINE_SWITCH, "h", "help", "show this help message",
            wxCMD_LINE_VAL_NONE, wxCMD_LINE_OPTION_HELP },
        // ... your other command line options here...

        { wxCMD_LINE_NONE }
    };

    wxCmdLineParser parser(cmdLineDesc, argc, wxArgv);
    switch ( parser.Parse() )
    {
        case -1:
            wxLogMessage(_T("Help was given, terminating."));
            break;

        case 0:
            // everything is ok; proceed
            break;

        default:
            wxLogMessage(_T("Syntax error detected, aborting."));
            break;
    }
    return 0;
}
