QListWidget-problem

[Sarma]

Hi all,
I am using QListWidget (as per my problem requirement).
Here is my code:
-------------

#include<qlistwidget.h>
#include<qlistwidgetitem.h>

listwidget=new QListWidget(this); //this is the user defined widget extending QWidget to which listwidget is added

new QListWidgetItem(tr("ONE"),listwidget,QListWidgetItem::Type);
new QListWidgetItem(tr("TWO"),listwidget,QListWidgetItem::Type);
new QListWidgetItem(tr("THREE"),listwidget,QListWidgetItem::Type);

Its giving me following errors:

"filter.cpp", line 11: Error: Could not open include file <qlistwidget.h>.
"filter.cpp", line 12: Error: Could not open include file <qlistwidgetitem.h>.
"filter.cpp", line 36: Error: The type "QListWidget" is incomplete.

First off, the proper include file should be #include<QListWidget> and why are you creating heap objects with no pointer?

[zlatko]

Are your QTDIR path is correct?

[zlatko]

First off, the proper include file should be #include<QListWidget>?

Its Qt4 style , for Qt3 #inlude<qlistwidget.h> is right

[jrideout]

Is there a QListWidget for qt3?

[zlatko]

Is there a QListWidget for qt3?
:D no of course its my missing

Also, as for my scoffing on just creating the heap objects, I realized this is ok as long as the parent is set. Qt holds the pointer in the parent and will destroy QListWidgetItem when the QListWidget is destroyed.

Check your QTDIR.

Also are you using Qt3 or Qt4? it's unclear from your post.
