error: expected unqualified-id before numeric constant

[yoblys]

Hi,

I'm using Qt4.1, and I had the same problem and I have resolved it with an include and a replacement :
#include <QKeyEvent> //that's very important
(QEvent::Type)6 instead of QEvent::KeyPress

example :
KeyEvent* kevent = new QKeyEvent((QEvent::Type)6,buffer[0],(Qt::KeyboardModifiers)Qt::NoModifier,buffer,fals e,1);

I hope it will help someone.

You sure don't have to use such ugly C-style casts when you have the necessary include directive in place.

#include <QKeyEvent>
...
QKeyEvent* kevent = new QKeyEvent(QEvent::KeyPress,buffer[0],Qt::NoModifier,buffer,false,1);

#include <QKeyEvent>
...
QKeyEvent* kevent = new QKeyEvent(QEvent::KeyPress,buffer[0],Qt::NoModifier,buffer,false,1);

I don't understand why you don't use enum Qt::Key for second parameter in QKeyEvent ctor?

The problem is likely that you are including X.h which has

// X.11.h
...
...
#define KeyPress 2

// X.11.h
...
...
#define KeyPress 2

To copy to clipboard, switch view to plain text mode 

So the preprocessor is converting this to...

QKeyEvent* kevent = new QKeyEvent(QEvent::2,buffer[0],Qt::NoModifier,buffer,false,1);

QKeyEvent* kevent = new QKeyEvent(QEvent::2,buffer[0],Qt::NoModifier,buffer,false,1);

To copy to clipboard, switch view to plain text mode 

Try adding

#undef KeyPress  // safe as long as you are not referencing KeyPress from X.h after this line
QKeyEvent* kevent = new QKeyEvent(QEvent::KeyPress,buffer[0],Qt::NoModifier,buffer,false,1);

#undef KeyPress  // safe as long as you are not referencing KeyPress from X.h after this line
QKeyEvent* kevent = new QKeyEvent(QEvent::KeyPress,buffer[0],Qt::NoModifier,buffer,false,1);

To copy to clipboard, switch view to plain text mode 

i.e. assuming that further down you won't be referring to KeyPress from X.h
