    Hi,

    I have a problem with qt creator. I study on "textEdit". I want to do "scanf" with textedit. Is it possible?

      Not sure i understand completely your question,
      Something like this would help :

      @
      class CMyMainWindow
      {
      public:
      CMyMainWindow()
      init();

      private slots:
      void nameChanged();

      private:
      QTextEdit m_textEditName;
      QString m_theName;
      }

      CMyMainWindow::int()
      {
      ...
      connect (m_textEditName, SIGNAL(textChanged()), this, SLOT(nameChanged()));
      }

      void CMyMainWindow::nameChanged()
      {
      m_theName = m_textEditName->toPlainText();
      }
      @

      The slot function "nameChanged()" will be called every time the textEdit is modified, updating the filed member "m_theName" (Thank to the "connect")

      (Perhaps a QLineEdit would be more suitable, no ?)

        In Qt we don't use the function "scanf", you can give what is there in a variable or you can work just wich is in the line edit or text edit.

        in line edit be this:

        @ui->lineEdit->text();@

        From all, to all.
