Initializing QTextStream with Text Edit...

[AlexanderAlexander]

I am trying to initialize a Q Text Stream with the plain text contents of my plain Text Edit, but am getting very bad results (I have done this successfully when reading from a file, but am confused with the Text Edit).

QTextStream inT(&this->textEdit_T->toPlainText());
QStringList dataT;
QString currLine;
while (!inT.atEnd()) {
	currLine = inTime.readLine();
	dataTime.append(currLine);
}

&this->textEdit_T->toPlainText()

This creates a temporary, so your QTextStream works on a dangling pointer.

Then what would be the proper way to create the Text Stream?

Don't use a temporary QString object - store the return value of textEdit_T->toPlainText() in a local variable.

But I would like to read it like a stream, line by line. If I store it in a local variable I am stuck with just a QString.

I don't understand your problem - why can't you pass the local QString object to QTextStream?

@christian-ehrlicher
If I take the resulting QString from textEdit->toPlainText() and initialize it a Text Stream with it will the endln's persist? Do you know how Text Edits handle wrapping when converting like this?

[Christian Ehrlicher]

I still don't understand your problem. I said you're passing a temporary to QTextStream since "&this->textEdit_T->toPlainText()" only creates a pointer to a temporary QString object. Therefore you should save the result of "textEdit_T->toPlainText()" and use this for your QTextStream.

Ok, I understand what you mean now. Thanks for the help m8
