reading QTextEdit from file

[incapacitant]

to write :

QFile file( s_filename );
  if (file.open(QIODevice::WriteOnly)) 
  {
    QTextStream os(&file);
    os << qMessage->toPlainText() << endl;
  }

QFile file( s_filename );
  if (file.open(QIODevice::WriteOnly)) 
  {
    QTextStream os(&file);
    os << qMessage->toPlainText() << endl;
  }

To copy to clipboard, switch view to plain text mode 

to read ?

qMessage << is; // 226

qMessage << is; // 226

To copy to clipboard, switch view to plain text mode 

compiler says :
226 C:\Qt\test\sms\menu.cpp no match for 'operator<<' in '((ApplicationWindow*)this)->ApplicationWindow::qMessage << is'
note C:\Qt\4.1.1\src\corelib\tools\qchar.h:291 candidates are: QDataStream& operator<<(QDataStream&, const QChar&) etc...

How can I read in one step as I wrote to the file ?

NB idem if I use to QString as for >>

[fullmetalcoder]

qMessage.setPlainText( is.readAll() )

qMessage.setPlainText( is.readAll() )

To copy to clipboard, switch view to plain text mode 

does that fit?

[incapacitant]

qMessage.setPlainText( is.readAll() );

qMessage.setPlainText( is.readAll() );

To copy to clipboard, switch view to plain text mode 

compiler says
226 C:\Qt\test\sms\menu.cpp `setPlainText' has not been declared

even with include <QTextEdit> !

looks like your textedit is a pointer while your previous code assumed it was not ( << operator doesn't work with pointers...)

try out "->" operator instead of "."
