一个弱弱的问题--wxString

Post by adream307 »

再次问一个弱弱的问题:
在wxWidgets中,如何把unsigned char *str类型的字符串复制给wxString。
例如:
unsigned char *str="123";
wxString s;
如何使s的内容成为"123"?
直接 s=str;编译出错。
谢谢!

s = wxString(str); 应该可以了。

也可以这样:

wxString s = _T("123");

s=(wxString)str不行,编译还是出错。
我想要的是将一个char *类型的字符串转换成wxString类型的。
谢谢!

Code: Select all

unsigned char *str="123"; 
wxString s(str);
用构造函数!

不是(wxString)str,是wxString(str)。两个是完全不同的。你用的那个是类型转换,是不存在的。我说的那个是构造函数。

请多翻阅文档:http://docs.wxwidgets.org/stable/wx_wxs ... inwxstring

你的是Unicode build吗?那么可能得这样做:

const char* ascii_str = "Some text";
wxString str(ascii_str, wxConvUTF8);

我是这样做的

#if wxUSE_UNICODE
#define WX2C(x) (wxString(x).mb_str(wxConvUTF8).data())
#else
#define WX2C(x) (wxString(x).mb_str(wxConvUTF8))
#endif

#define C2WX(x) (wxString(x, wxConvUTF8))

我都是
wxString s = wxT("Some text");

regardless of Unicode/ANSI version.
