QTextEdit error

[scrasun]

I am trying to compile a program that contains:

#include <QTextEdit>
//some code
QTextEdit *textbox=new QTextEdit;
//some code
textbox->text();
//some code

#include <QTextEdit>
//some code
QTextEdit *textbox=new QTextEdit;
//some code
textbox->text();
//some code

To copy to clipboard, switch view to plain text mode 

but I keep getting the error: "error: ‘class QTextEdit’ has no member named ‘text’"
p, li { white-space: pre-wrap; }
Does anyone know why this is happening or how to solve it.
Any help is appreciated
