QString character erase function

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 ?

Answer 1

line = line.remove(index,1);

see the documentation

Answer 2

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(' ');

Answer 3

You can use

line.replace(QString(" "), QString(""));
