QGLWidget and keyPressEvent

[abroadcom.hk]

Ηi,
The code that follows responds for keyboad and adjust the size of window

but in
@
NeHeWidget::NeHeWidget( QWidget* parent, const char* name, bool fs )
: QGLWidget( parent, name )
{
fullscreen = fs;
setGeometry( 0, 0, 640, 480 );
setCaption( "NeHe's OpenGL Framework" );

if ( fullscreen )
showFullScreen();
}@
NeHe is children of QGLwidget.
QT Creator reports :no matching function for call to 'QGLWidget::QGLWidget(QWidget*&, const char*&)'
and 'setCaption' was not declared in this scope.

also in
@
void NeHeWidget::keyPressEvent( QKeyEvent *e )
{
switch ( e->key() )
{
case Qt::Key_F2:
fullscreen = !fullscreen;
if ( fullscreen )
{
showFullScreen();
}
else
{
showNormal();
setGeometry( 0, 0, 640, 480 );
}
updateGL();
break;
case Qt::Key_Escape:
close();
}
}
@
it reports invalid use of incomplete type 'struct QKeyEvent' and forward declaration of 'struct QKeyEvent'
Is this because of the vesion of my QT?

Looks like some #includes are missing.

Do you include? @#include "NeHeWidget.h"@
