How can we remove space only from the end of string?
-
ex - @Hello Qt . . .@
The number of space may vary.

There is no build-in rtrimmed or ltrimmed function that I am aware of. So, easiest way is to just create a simple function that does that yourself.
It could be as simple as (brain to terminal, not tested)
@
QString rtrimmed(const QString input)
{
QString result = input;
while (result.count() > 0 && result[result.count()-1)].isSpace() ) {
result = result.left(result.count() -1 );
}return result;
}

Since trimmed removes also spaces at the beginning, you have to do a loop over each character in your string and then truncate:
@
int truncateAt = myString.size();
for( ; truncateAt > 0; truncateAt-- )
if( ! QChar.isSpace( myString.at( truncateAt ) )
break;myString.truncate( truncaetAt );

I would go with a regex:
@
QString ttt = " Qt . . . ab ";
qDebug() << "ttt" << ttt;
ttt.replace(QRegExp("\s*$"), "");
qDebug() << "tt2" << ttt;// output:
// ttt " Qt . . . ab "
// tt2 " Qt . . . ab"
