This thread is 4 years old, but I want to give a solution anyway.
I spent the past 2 months trying to figure out how to do this, and all the threads I found are talking about issues but nobody gave me a solution.

Actually, the QWidget you create has its own focus but is not "parent" of the HWND you are embedding on it, so you have to make the keyboard focus by yourself.

The best way to do that is by using the SetFocus function of the winuser library (WinUser.h):
https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-setfocus

Like, in example:

m_qwindow = QWindow::fromWinId(m_handle); m_widget = QWidget::createWindowContainer(m_qwindow, this); // tell the os to focus the viewport window SetFocus(m_handle);

with m_handle being the HWND (or WId) used to create the QWindow.

Unfortunately, this solution works only on windows (but maybe there are equivalents on another os).
It also doesn't work when clicking on the embedded window, because it isn't owned by Qt.
maybe you can try to mess with QFocusFrame (I haven't tried this at all, but it should be a way to use it as a fix by putting it over the embedded window)
or, if the window you are embedding is one of your creations, put the SetFocus() function in its code, as a callback when clicked.

I hope that even with 4 years late, this solution is still helping the desperate developers like who I was the past two months.

@Zylann Great! :)

Please, mark the post as solved ;)

Hi @choas, and welcome to the Qt Dev Net!

The goal is to combine/use existing C++ libraries (photo/image processing) from other projects as part of the business layer in combination with databases.

Since you're going to write lots of C++ code, go with Widgets. Integration will be much easier.

What's with performance, future Qt development etc.?

Widgets have great performance for desktop-style GUIs. Qt Quick's performance shines when you want to do very fancy things like particle animations.

As for the future, Qt Quick is receiving lots of attention, but it cannot fully replace Qt Widgets yet. Widgets will be around for many years to come.

Is the "Widget-way" still actual for desktop or slowly dying?

It's not dying. :) (you'll hear some people say that it's dying because it's not receiving as much attention compared to Qt Quick, but you need to remember that Qt Widgets is a very mature product, that's why it doesn't need as much attention)

@pmh4514

maybe you can use the QDesktopWidget

int QDesktopWidget::screenNumber(const QWidget * widget = 0) const Returns the index of the screen that contains the largest part of widget, or -1 if the widget not on a screen.

Hi,

You have the ICS Qt based google APIs clients

As for licensing, you should ask Google directly

Opa,

Ótimas dicas.

Eu já tinha sondado o openstreet map antes, pelo fato de ser gratuito. Mas achei a documentação muito fraca. As outras soluções suportadas pelo Qt Location exigem licença enterprise para o meu tipo de aplicação. Ai acho que pagar por pagar melhor ficar com o google.
Ainda não tenho certeza que tipo de licença seria necessário para uma aplicação desktop para fins corporativos.

Sounds like it could be a bug like a platform detection problem since Windows 8.1 is very tablet looking even on desktop computers. You should take a look at the bug report system to see if it's something known

i solved problem by download other version of Qt Qt 5.5.0 for Windows 32-bit (MinGW 4.9.2, 959 MB)
THANKS

@danks_
That is good to hear !
Could also been some kind of setup problem with 5_5 but yeah it does
seems like a bug.

I will try with 5_5 and see it it fails for me too.

update:
Tested win pure 5_5 install
It worked by copying the DLLs ! ?
Even worked with no sub sqldrivers folder ...!
(in the release folder)

But when moved out of the virtual machines
it did want the sqldrivers folder to work.

So the current version of 5.5 via the online installer does seems to work in regards to sql.?!

@cybercatalyst You're right.

Thanks for your answers anyway, it really helped me. ;)

Hi @LuisEnrique,
The Qt way to do it is using QString::number.

Hola

Como siempre digo, lo mejor que puedes hacer es acostumbrarte a consultar la documentación, en el caso de Qt es muy clara y completa.

Para convertir el número tienes el método int toInt(bool * ok = 0, int base = 10) de la clase QString:
http://doc.qt.io/qt-5/qstring.html#toInt

En el QLineEdit puedes usar una máscara para asegurarte que solo se introducen números:
http://doc.qt.io/qt-5/qlineedit.html#inputMask-prop

Para acceder al contenido del QLineEdit el método a usar es text():
http://doc.qt.io/qt-5/qlineedit.html#text-prop

Un saludo

Hi and welcome to devnet

A featrure as you request may be latest with larger projects too much for the debugger to handle.

The closest to get such a behaviour is to use F11 and Shift+F11. F11 will enter every possible method and Shift+F11 will help you to run the remainder of the method. IMO sufficient enough to get a really detailed anaylsis of source code.

Hi thanks,

Finally I found libproxy, I will try to see if it does what I want.

Best regards,
Alexis.

Good !

However, I'm not sure I'm following you on that one. Where did you put that resize ?

If you can't from the Topic Tools menu, then just edit the thread title and prepend [solved]

Hello svyatoslav,
Yes I had already referred this URL, that is not enough
Thanks you very much for responding
