[Interest] Interesting problem with properties.

[Igor Mironchik]

Hi,

I have class NavigationButton that derived from QAbstractButton. 
NavigationButton redefines property QString: text.

In my application I have one such button and initialize it with the 
following code:

sendButton = new QtMWidgets::NavigationButton(
         QtMWidgets::NavigationButton::Right, QObject::tr( "Send" ), q );

First setText() invokes with "Send" text from constructor of 
NavigationButton, it's normal. But I have second invoke with "&Send".

What is the problem can be?

Bellow stack trace of the second invoke:

0    QtMWidgets::NavigationButton::setText navigationbutton.cpp    
147    0x424ae3
1    QtMWidgets::NavigationButton::qt_metacall 
moc_navigationbutton.cpp    148    0x42ed6a
2    QMetaProperty::write(QObject *, QVariant const&) const         
0x7ffff65d7b60
3    QObject::setProperty(const char *, QVariant const&)     0x7ffff65ffca3
4    ??            0x7fffe70792ed
5    ??            0x7fffe707a95b
6    ??            0x7fffe7611723

11    QApplicationPrivate::notify_helper(QObject *, QEvent *)     
0x7ffff76af2b4
12    QApplication::notify(QObject *, QEvent *) 0x7ffff76b2c86
13    QCoreApplication::notifyInternal(QObject *, QEvent *)     
0x7ffff65cae24
14    QTimerInfoList::activateTimers()            0x7ffff6624a54
15    ??            0x7ffff6624cfd
16    g_main_context_dispatch            0x7ffff52cfc3d
17    ??            0x7ffff52cff20
18    g_main_context_iteration            0x7ffff52cffcc
19 
QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) 
         0x7ffff6625643
...    <More>

And again: second invoke receive "&Send" as argument. From where this 
"&" appears?

Thank you.

P.S. In my code there is no setText() invokes...
