I want to remove all the trailing whitespace characters in a QString
. I am looking to do what the Python function str.rstrip()
with a QString
.
I did some Googling, and found this: http://www.qtforum.org/article/20798/how-to-strip-trailing-whitespace-from-qstring.html
So what I have right now is something like this:
while(str.endsWith( ' ' )) str.chop(1);
while(str.endsWith( '\n' )) str.chop(1);
Is there a simpler way to do this? I want to keep all the whitespace at the beginning.
QString
has two methods related to trimming whitespace:
QString QString::trimmed() const
QString QString::simplified() const
If you want to remove only trailing whitespace, you need to implement that yourself. Here is such an implementation which mimics the implementation of trimmed
:
QString rstrip(const QString& str) {
int n = str.size() - 1;
for (; n >= 0; --n) {
if (!str.at(n).isSpace()) {
return str.left(n + 1);
}
}
return "";
}
