在C++里常用类型转换感觉很杂,不好用;跟C#没得比:可以强类型转换,还有convert通用的转换,非常方便的说。
刚用wxwidget时类型转换也是一头大,了解后发现要比MFC简洁好用多,接口也容易记住。
下面上WXWIDGET常用类型转换:
一、wxstring与其他类型转换
1.1 int to wxString: wxString str = wxString::Format(wxT("%i"),myInt);
1.2 wxString to int : int i; i = wxAtoi(str);
1.3 string to wxString: std::string stlString = "sdfas"; wxString mystr(stlString .c_str(),wxConvUTF8);
1.4 wxString to string:
wxString mystring(wxT("HelloWorld"));
std::string stlstring = std::string(mystring.mb_str());
1.5 char* to wxString:
char* chars = "Hello world";
wxString mystring(chars, wxConvUTF8);
1.6 wxString to char*: char* cs = str.mb_str(wxConvUTF8);
1.7 char[] to wxString:
char chars[34] = "sefasd";
string mystring(chars, wxConvUTF8);
1.8 wxString to char[]:
wxString mystring(wxT("HelloWorld"));
char cstring[1024];
strcpy(cstring, (const char*)mystring.mb_str(wxConvUTF8));
二、wxdatetime 与wxstring转换
2.1 wxdatetime to wxstring :
wxDateTime dt = CalendarCtrl1->GetDate();
wxString msg = dt.Format(wxT("%Y-%m-%d"),wxDateTime::A_EST);
2.2 wxstring to wxdatetime: char* ca = "2008-09-03";wxDateTime dt;dt.ParseDate(ca);
