Read CSV and parse
-
Hi all.
I am new with Qt.
I need to create a code that will read a selected csv file in any folder and extract the information.
The data in the csv file is numbers.
The format is:
Column, point, latitude (DDMMSS.ss hemisphere), longitude (DDMMSS.ss hemisphere), X (UTM), Y (UTM), data 1, data2).
I used QString and Openfiledialog to indicate the file and read.
How do I read the information line by line? -

@Renato_Brasil
and for splitting, please see
http://doc.qt.io/qt-5/qstring.html#split
it will u give u a list of all the keys pr lineps. if huge file please read about the
QVector<QStringRef> QString::splitRefits has better performance than the other but if small file and Desktop app, it wont matter much.
