The TQConstString class provides string objects using constant Unicode data.
< p > In order to minimize copying, highly optimized applications can
use TQConstString to provide a < a href = "tqstring.html" > TQString< / a > -compatible object from
existing Unicode data. It is then the programmer's responsibility
to ensure that the Unicode data exists for the entire lifetime of
the TQConstString object.
< p > A TQConstString is created with the TQConstString constructor. The
string held by the object can be obtained by calling < a href = "#string" > string< / a > ().
< p > See also < a href = "text.html" > Text Related Classes< / a > .

< h3 class = fn > < a name = "TQConstString" > < / a > TQConstString::TQConstString ( const < a href = "qchar.html" > TQChar< / a > * unicode, uint length )
< / h3 >
Constructs a TQConstString that uses the first < em > length< / em > Unicode
characters in the array < em > unicode< / em > . Any attempt to modify copies
of the string will cause it to create a copy of the data, thus it
remains forever unmodified.
< p > The data in < em > unicode< / em > is not copied. The caller must be able to
guarantee that < em > unicode< / em > will not be deleted or modified.
< h3 class = fn > < a name = "~TQConstString" > < / a > TQConstString::~TQConstString ()
< / h3 >
Destroys the TQConstString, creating a copy of the data if other
strings are still using it.
< h3 class = fn > const < a href = "tqstring.html" > TQString< / a > & < a name = "string" > < / a > TQConstString::string () const
< / h3 >
< p > Returns a constant string referencing the data passed during
construction.
