eventFilter: test if enter a subWidget in my subclassed QWidget

[vonCZ]

I've subclassed QWidget to make a button panel: BuPan. BuPan consists of buttons, a slider, and checkBoxes: it's a small panel that pops up next to a QPushButton in my mainApplication like so:

bool Window:eventFilter(QObject *obj, QEvent *event)
{
  if(event->type() == QEvent::Enter)
  {
    if(obj == myQPushButton)
    {
      myBuPan->move(xloc, yloc);
      myBuPan->show();
      return QWidget::eventFilter(obj, event)
    }
    etc...
}

bool Window:eventFilter(QObject *obj, QEvent *event)
{
  if(event->type() == QEvent::Enter)
  {
    if(obj == myQPushButton)
    {
      myBuPan->move(xloc, yloc);
      myBuPan->show();
      return QWidget::eventFilter(obj, event)
    }
    etc...
}

To copy to clipboard, switch view to plain text mode 

pb[0] is a button in myBuPan. I want to check for an Enter event on this particular button within BuPan; I thought I could do the following:

bool Window:eventFilter(QObject *obj, QEvent *event)
{
  if(event->type() == QEvent::Enter)
  {
    if(obj == myQPushButton)
    {
      myBuPan->move(xloc, yloc);
      myBuPan->show();
      return QWidget::eventFilter(obj, event);
    }
    if(obj == myBuPan->get_pb(0))
    {
      qDebug("HIT!!");
      return QWidget::eventFilter(obj, event);
    }
    etc...
 
// ...and I have the following in bupan.h:
 
    QList<QPushButton *> pb;
    QPushButton *get_pb(int value)    { return pb[value]; }

bool Window:eventFilter(QObject *obj, QEvent *event)
{
  if(event->type() == QEvent::Enter)
  {
    if(obj == myQPushButton)
    {
      myBuPan->move(xloc, yloc);
      myBuPan->show();
      return QWidget::eventFilter(obj, event);
    }
    if(obj == myBuPan->get_pb(0))
    {
      qDebug("HIT!!");
      return QWidget::eventFilter(obj, event);
    }
    etc...

// ...and I have the following in bupan.h:

    QList<QPushButton *> pb;
    QPushButton *get_pb(int value)    { return pb[value]; }

To copy to clipboard, switch view to plain text mode 

Shouldn't this work? ...er, it's not. ...ideas?

Or will I have to add an "enterEvent(QEvent *event)" method to the BuPan class itself? If I have to do this second option: How can I write the bupan "enterEvent" method so that it's generic... for example, so that pb[0] and pb[2] will capture enterEvents on one instance of BuPan, but on another instance only pb[4] might capture the events?
