Question
QString line = "example string";
Now I want to erase the space between 'example' and 'string' so that I get a string like this "examplestring". Is there a function in Qt which erases a character under the given index or should I write this function myself ?
Solution 2

OTHER TIPS
What about QString::remove(QChar ch, Qt::CaseSensitivity cs = Qt::CaseSensitive)
function? You can use ' ' as a first argument. I.e.:
QString line = "example string";
line.remove(' ');
You can use
line.replace(QString(" "), QString(""));
