d_func problem

[cookieki]

Hi,All.
I got the problem when subclassing QListWidgetPrivate.

#include <private/qlistwidget_p.h>
...
QItemSelectionModel::SelectionFlags QListWidgetPrivateEx::selectionCommand(const QModelIndex &index,const QEvent *event) const
{
	Q_D(const QAbstractItemView);
...
}

#include <private/qlistwidget_p.h>
...
QItemSelectionModel::SelectionFlags QListWidgetPrivateEx::selectionCommand(const QModelIndex &index,const QEvent *event) const
{
	Q_D(const QAbstractItemView);
...
}

To copy to clipboard, switch view to plain text mode 

compiler(vs2003) shows error.
'd_func': identifier not found, even with argument-dependent lookup
What's the problem?

You've neglected to include some other header file needed by qlistwidget_p.h that contains the definition of 'd_func'.

[cookieki]

what's that file?

I have no idea. Private implementations have no documentation in Qt. Grep around in the include directories where you found the private file you're using and see if you can locate where this particular d_func is defined.

Note that deriving from private implementations isn't something you should normally attempt. I assumed you knew what you were doing when you decided to go down that road. If you didn't, you should rethink your approach.

I think they are in QtGlobal.h

Why would you even want to subclass QListWidgetPrivate?

sorry, wait please. I'm changing post.
