How can I read from Text Edit

**sujan.dasmahapatra** · 12th October 2009, 09:26

Dear Friends
I have some values in Text Edit in the dialog box , the values are like below
2 0.323 0.3232
1st values is an ineteger and the rest two are doubles.

How can I read these values independently from Text Edit. !!

Any suggestion would be appreciated.

you can't. grab the (complete) text as a QString and parse it.
You can use QTextStream for reading the numbers.

Qt Code:

Switch view

QString text = edit->toPlainText();
QTextStream ts(&text, QIODevice::ReadOnly);
double f1, f2, f3;
ts >> f1 >> f2 >> f3;

QString text = edit->toPlainText();
QTextStream ts(&text, QIODevice::ReadOnly);
double f1, f2, f3;
ts >> f1 >> f2 >> f3;

To copy to clipboard, switch view to plain text mode

would this reading be sequential reading ??

Hi, i have created a project(Gui project) and in the main.cpp file i have some sql queries that gets data from a remote sever liekt this;
if(!query.exec("SELECT..........")){
qDebug()<<"FAIL";
}
while(query.next()){

qDebug() << name;
}
