QAxWidget don't display

[lvshuchengyin]

I use QWidget as a dialog. And put QAxWidget as a subwidget.
But if I set the parent widget transparent, the QAxWidget will not display.

@
QWidget* widget = new QWidget;
widget->setAttribute(Qt::WA_TranslucentBackground);
......;

QAxWidget* axBrowser= new QAxWidget(widget);
axBrowser->setControl(QString::fromUtf8("{8856F961-340A-11D0-A96B-00C04FD705A2}"));
axBrowser->dynamicCall("Navigate(const QString&)", "www.google.com");
@

I try if you use other widget, that will display, only QAxWidget don't display!
