为什么 Clion 不识别 WxPuts? [英] Why doesn't Clion recognise WxPuts?

问题描述

本教程中使用的 wxPuts 方法(http://zetcode.com/gui/wxwidgets/helperclasses/) 不起作用.是否已更改并且课程不再可用?

The wxPuts method used in this tutorial (http://zetcode.com/gui/wxwidgets/helperclasses/) doesn't work. Was it changed and the class is no longer available?

我尝试在网上搜索有关 wxPuts 和 wxPrintf 的一些文档，但在 wxWidg 站点的帮助文件中找不到任何相关内容.

I tried searching online for some documentation about wxPuts and wxPrintf, but can't find anything relevant in the helper files in the wxWidg site.

#include <wx/textfile.h>

int main(int argc, char **argv)
{

    wxTextFile file(wxT("test.c"));

    file.Open();

    wxPrintf(wxT("Number of lines: %d\n"), file.GetLineCount());
    wxPrintf(wxT("First line: %s\n"), file.GetFirstLine().c_str());
    wxPrintf(wxT("Last line: %s\n"), file.GetLastLine().c_str());

    wxPuts(wxT("-------------------------------------"));

    wxString s;

    for ( s = file.GetFirstLine(); !file.Eof();
          s = file.GetNextLine() )
    {
        wxPuts(s);
    }

    file.Close();
}

推荐答案

wxWidgets 为所有处理字符串的标准 CRT 函数提供包装器，以便允许使用 wxString 或 wchar_t(宽)字符串.这些包装器没有记录，因为重新记录标准函数没有多大意义，但基本上对于标准库中的任何 foo(const char* s)，你都有 wxFoo(const wxString& s) 在 wx/crt.h 标头中声明.但是，您必须包含此标头才能获得这些声明.

wxWidgets provides wrappers for all standard CRT functions working with strings in order to allow calling them with wxString or wchar_t (wide) strings. These wrappers are not documented because it doesn't make much sense to re-document the standard functions, but basically for any foo(const char* s) in the standard library, you have wxFoo(const wxString& s) declared in wx/crt.h header. You have to include this header to get these declarations, however.

另请注意，在 库初始化之前无法使用大部分 wxWidgets 功能.

TL;DR:你错过了 #include <wx/crt.h>.

TL;DR: you're missing #include <wx/crt.h>.
