Typedef Documentation

typedef WString Wt::WMessage

Deprecated Alias to WString for the depreacated WMessage classes.

WString provides all the functionality of WMessage, but is used more consistently through the interface everywhere wide character support is needed, instead of previously std::wstring.

Function Documentation

int WTCONNECTOR_API Wt::WRun	(	int	argc,
		char **	argv,
		Wt::WApplication::ApplicationCreator	createApplication
	)

Entry point for a Wt application.

This function must be called in the main of your application. The createApplication parameter is a function pointer that creates a Wt application.

std::wstring Wt::widen ( const std::string & s )

Convert a narrow to a wide string.

Convert a narrow string to a wide string. This method will not perform any code conversion, it simply represents the same string with a same number of wide characters.

See also:: narrow(const std::wstring&), fromUTF8(const std::string& s)

std::string Wt::narrow ( const std::wstring & s )

Convert a wide to a narrow string.

Convert a wide string to a narrow string. This method will not perform any code conversion, it simply represents (as far as possible) the same string with a same number of narrow characters.

In general this will lead to a loss of information. If you wish to preserve all information, you should us toUTF8() instead.

See also:: widen(const std::string&), toUTF8(const std::wstring& s)

std::wstring Wt::fromUTF8 ( const std::string & s )

Decode a UTF8 string a wide string.

Decode a UTF8 string to a wide string. In a UTF8 encoded unicode string, some unicode characters are represented in more than one byte. This method will decode to extract the proper unicode characters from the string. The resulting string may thus be shorter (has less characters) than the original, but does not lead to a loss of information.

See also:: toUTF8(const std::string& s), narrow(const std::wstring&)

std::string Wt::toUTF8 ( const std::wstring & s )

Encode a wide string to UTF8.

Convert a wide string to UTF8. This method will encode the given wide string in UTF8. This may result in a string that is possibly longer (has more characters), but does not lead to a loss of information.

See also:: fromUTF8(const std::string& s), narrow(const std::wstring&)

template<typename ViewRenderer>

WStaticModelView<ViewRenderer>* Wt::makeStaticModel	(	ViewRenderer	f,
		WContainerWidget *	parent = `0`
	)

Wrap a widget into a view with a non-changing model.

The ViewRenderer is called without arguments and must return a newly created widget (WWidget *).
