reading a file

[xaqt]

Hi everyone;

I'm trying to read a .txt file with a simple window design. After i manage to read the .txt file i'll try to read .csv file.

Firstly is there a big difference between reading .txt files and .csv files. ?

and second, I've a textBrowser and a button just like this.

void read::on_readButton_clicked()
{
//?
}

void read::on_readButton_clicked()
{
//?
}

To copy to clipboard, switch view to plain text mode 

what should I write here ? Same way with simple c/c++ methods ?
