FramelessWindowHint freezes form with QAxWidget

[mrjj]

well my "theory" is that
if QAxWidget is assigned to a parent before FramelessWindowHint
then bug comes.

[Tikitko]

@mrjj Then the solution is not to create QAxWidget in the constructor?

[mrjj]

Well I assume u tested that ?
Create it after setupUI and FramelessWindowHint does not make it work ?

If no, you can try with the showEvent
void maiwinxx::showEvent( QShowEvent* event ) {
QMainwindxx::showEvent( event );

// create it here.

}

@mrjj i create:

void MainWindow::showEvent( QShowEvent* event ) {

    QAxWidget *Test = new QAxWidget(this);
    Test->setControl("{8856f961-340a-11d0-a96b-00c04fd705a2}");
    Test->dynamicCall("Navigate(const  QString&)","http://vk.com/");
    Test->show();

}

Not help...
Excuse me, I find it hard to understand you, because I'm Russian ...

@Tikitko
Hi, np. That was what i wanted to test.

So if we create it before windows is fully shown we get bug?

But if you create in button_click , it works?

[Tikitko]

@mrjj Yes, once checked, it is so ...

[mrjj]

@Tikitko
very strange!
I though showEvent would been same as clicked.
Try timer so that we first create after window fully shown.

// in constructor
QTimer *timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(nowcreate()));
timer->start(4000);
}

void MainWindow::nowcreate() << add this to .h also
{
qDebug() << "nowcreate";
// create here
QAxWidget *Test = new QAxWidget(this);
..
}

[Tikitko]

@mrjj This work!

[mrjj]

@Tikitko
ok
so window must be fully shown to make it happy.
Good testing :)

[Tikitko]

@mrjj Thank you very much for your help! So show window, and then create a widget ... So still the question, it is a bug Qt or something else? The problem can be considered solved only in the bug tracker you need to add ...

[mrjj]

@Tikitko
You are most welcome.
well I think its a bug but not sure.
When bug comes, it seems to me it hangs. That seems like bug.

Oh I forgot to ask.
What is {8856f961-340a-11d0-a96b-00c04fd705a2} ?

[Tikitko]

@mrjj this is Internet Explorer but in any case, the error with any object in QAxWidget...

[Tikitko]

@mrjj Hello, another mament noticed everything was decided widget loading after displaying the window, but if you minimize the window and deploy the freeze button again ...

[mrjj]

@Tikitko
Ehh. not sure I read that correctly.

You say that if made with button, then bug dont show, but if you minimize and maxi window again, bug comes back?

[Tikitko]

@mrjj If i minimize a window, and deploy it, the problem returns

[mrjj]

Ok
Have you tried with Qt 5.5 ?
Maybe QAxWidget has bug in 5.6

Hello!

I faced a similar problem, tried hacks with single QTimer and showEvent: timer was a solution, and showEvent -- wasn't. I also use Win10, but Qt5.5.1. Have you succeeded?
