I got it wrong, can't compile

[wysota]

You didn't implement the constructor for the ListDelegate class.

How do I implement it? I thought that ListDelegate(QObject *parent=0);was the constructor for the ListDelegate class.

Come on, man. It's a declaration of the constructor. Where is its body?

Don't kill me for asking, but how do I implement it? The video didn't write anything else, the source code, QAbstractItemDelegate.cpp the body of the constructor is blank , it's just like that:

QAbstractItemDelegate::QAbstractItemDelegate(QObject *parent = 0)
{
 
}

QAbstractItemDelegate::QAbstractItemDelegate(QObject *parent = 0)
{

}

To copy to clipboard, switch view to plain text mode 

And now when I try to compile I get this other error:

F:/Documents/QT Projects/QListView_test/main.cpp:10: error: no matching function for call to 'QListView::setItemDelegate(ListDelegate&)'
c:\Qt\2009.05\qt\include\QtGui/../../src/gui/itemviews/qabstractitemview.h:135: note: candidates are: void QAbstractItemView::setItemDelegate(QAbstractItemDelegate*)

Im trying to understand, doing my best. Thanks for your help.

For some unknown reason it compiled and now runs perfectly. With main :

ListDelegate delegate;
 
QListView view;
 
view.setItemDelegate(&delegate);
 
view.show();

ListDelegate delegate;

QListView view;

view.setItemDelegate(&delegate);

view.show();

To copy to clipboard, switch view to plain text mode 

And ListDelegate constructor:

ListDelegate::ListDelegate(QObject *parent = 0)
{
 
}

ListDelegate::ListDelegate(QObject *parent = 0)
{
 
}

To copy to clipboard, switch view to plain text mode 

I still am clueless as to why. I read the pixelator example on QT, and it's custom delegate class constructor is the same as mine, empty.
Now if I try to use a custom QAbstractListModel I get the same issues as I previously had with QAbstractItemDelegate.

The unknown reason is that you added the body of the constructor.

Ok. Thanks for your help.
