Convert a multiline QString into a one line QString
Question
I have something like this:
void ReadFileAndConvert ()
{
QFile File (Directory + "/here/we/go");
if(File.open(QIODevice::ReadOnly | QIODevice::Text))
{
QTextStream Stream (&File);
QString Text;
do
{
Text = Stream.readLine();
Text = Text.simplified();
// Here I want to convert the multiline QString Text into a oneline QString
// ...
}
The QString Text consists of a multiline Text that I need to convert into a online Text/QString. How can I achieve this? greetings
Solution
Put your text into a QStringList
, and use QStringList::join()
, e.g.
QStringList doc;
[...]
Text = Stream.readLine();
Text = Text.simplified();
doc << Text;
[...]
QString final = doc.join(" ");
OTHER TIPS
You could use the readAll
function of QTextStream
in order to get a string containing all your text and then use the replace
function of QString
in order to remove new lines:
QString oneLineText = Stream.readAll().replace("\n"," ").simplified();
If you have a large file it is better to use the readLine
function.
