Insert something into certain line and column of text file

[hajh90]

Something like:

• Open file you wish to insert into. QTextStream
• Open a temporary file to hold the result. QTextStream and QTemporaryFile
• Loop 10 times reading a line from the input file and writing it to the output.
• Read the 11th line from the input
• Insert the value into the line at character 19. QString::insert() and QString::number()
• Write the modified line to the output
• Loop over remaining lines in the input file, writing each to the output file
• Close both files
• If there have been no errors copy the temporary file over the original file. QFile::copy()

If the files are small then this can be done by reading the entire file into a QStringList, manipulating it in memory, then writing the result. There is more than one way to do this.

Thanks a lot. Can you explain more detail how to use these command to make code? I am newbie.
