insert number to qtextEdit

Hi

How Can insert number to qtextEdit ??

No need to yell.

What's wrong with QTextEdit::setPlainText()?

And to put a number in it, use e.g. :

Code:

---

ui->myEdit->setPlainText( QString::number(  123  ));

---

Now I want using QlineEdit
as,

Code:

---

ui->lineEdit->textEdited( QString::number(  123  ) );

---

But i see this error,
error: 'void QLineEdit::textChanged(const QString&)' is protected

textEdited() is a signal.

How about you try to describe what you are trying to achieve overall (in English not code) rather than firing off queries about each line of your code out of context. It strikes me that you might be better off with a QLineEdit or a QSpinBox if you are going to be soliciting numbers from the user.

I want a way to:
Get values from the user.
Put the values in the box.

Do you use the QLineEdit or qtextEdit :confused:

For, Get values from the user:

Code:

---

int x = ui->textEdit->toPlainText().toInt(&ok,10);
//Or
QString x = ui.textEdit->toPlainText();

---

and for, Put the values in the box:

Code:

---

ui->textEdit->setPlainText( QString::number( 123 ));

---

Use QSpinBox instead of QTextEdit. QTextEdit is for multi-line text, that's not what you want.
