QT4 编译出错 代码如下 求高手指导

void CannonField::paintEvent(QPaintEvent *e)
{
if( !e->rect().intersects(cannonRect()))
return;
QRect cr=cannonRect();
QPixmap pix(cr.size());
pix.fill(this,cr.topRight());
QPainter painter (&pix);
painter.setRenderHint(QPainter::Antialiasing,true);
painter.setPen(QPen(Qt::blue));
painter.setBrush(QBrush(QBrush(Qt::blue)));
painter.translate(0,pix.height()-1);
painter.drawPie(QRect(-35,-35,70,70),0,90*16);

painter.rotate(-currentAngle);
painter.drawRect(33,-4,15,8);
painter.end();
painter.begin(this);
painter.drawPixmap(cr.topLeft(),pix);

QRect updateR = e->rect();
QPainter p( this );

if ( updateR.intersects( cannonRect() ) )
paintCannon( &p );

if ( autoshoottimer->isActive() && updateR.intersects( shotRect() ) )
paintShot( &p );

}
void CannonField::paintEvent( QPaintEvent *e )
{ QRect updateR = e->rect();
QPainter p( this );

if ( updateR.intersects( cannonRect() ) )
paintCannon( &p );

if ( autoshoottimer->isActive() && updateR.intersects( shotRect() ) )
paintShot( &p );

}

代码如下： module clk(clk_in,q); input clk_in; output[7:0] q; 1、进程里面不能调用模块，只能调用函数或者任务，然而在clk模块里含有always
