QQuickWindow in 5.12

J.Hilk

How would I manage the includes in the designer? So far that's been handeld automatically.

The interesting thing is, if created inside the normal class it compiles normaly. Seems to be an issue with the automatically generated ui_className.h file.

this works:

{
    ui->setupUi(this);

    QQuickWidget *w = new QQuickWidget(this);
    ui->verticalLayout->addWidget(w);
    w->show();
}

but adding it directly to the verticalLayout via designer, does not.

Depends on how you added the widget. If you just dragged a standard one it should work out of the box. If you have promoted you specify the header, thus you shouldn't use scoped includes. Can you post the generated ui header, the project file and a grep-ed portion of the makefile that shows the target for the particular object (i.e. ui_mainwindow.o and/or ui_mainwindow.h)?

That's expected. The problem is in the build chain, not in the compilation. If you don't have that object in the makefile there shouldn't be an error.

sure,
here you go:

I would post the other files, but nothing is generated the folders moc and obj and ui are empty.

I could post the Makefile that's the only other file generated besides and arbitrary app-bundle

Maybe my iOS precompiled libary is horribly broken. Because I'm also unable to use import QtQuick.Dialogs because that one depends on QtQuick.Controls 1.2 which it does not find.
Qt Quick Controls 1 is marked as deprecated, I know, but QtQuick.Dialogs is not.

But only on iOS of course, loads fine on macOS.

Technically I don't use the FileDialog on iOS and android, but I don't think theres someting similar for QML as there is for c++ ?

#if defined(Q_OS_WIN) || defined(Q_OS_MACOS)
   FileDialog {

  }
#endif

Edit:
I was able to fix that FileDialog issue with a Loader and a check for Qt.platform.os === "ios" to set the source or not.

That's probably the reason you get that error. Try commenting out the OBJECTS_DIR and the other qmake vars.

I'll try it , but I doubt it will change anything. I added the qmake vars because I couldn't find any generated files in the build folder and thought I had gone mental x)

I'll report back.

kshegunov

Okay, this is mighty odd. Please run qmake with -d or -d -d and get us some logs to inspect. Something definitely smells fishy ...

PS:
If you want to generate the intermediate files in a separate dir, this is what I use:

OBJECTS_DIR = $$DESTDIR/.obj/$$TARGET
// ...

Works fine for me.

J.Hilk

@kshegunov
alright, will do. May take a moment.
At the moment I'm fixing all kind of issues, apparently precompiled 5.12 ios libs do not come with QQuickControls 1 enabled, which I need. So my Mac is currently busy compiling it from source.

@kshegunov
ok this, is the entirety of the build folder after the fail
0_1544793006783_56983d77-6d8a-43a0-bd04-185db420a935-image.png

this is the console output of qmake run with -d argument
out put is to long t post it here, I crop it to the last couple lines that handle the QQuickWidget

Ok, some more updates,

If I remove the QQuickWidget and run make to generate all needed files, and than add the QQuickWidget and hit compile/run it works.
BUT if I force a qmake rerun, it failed!

-> running make without QQuickWidgets in the ui -> than adding QQuickWidgets -> everything works fine

but as soon as I need to generate the files a new aka, deleting build folder or forcing a manual qmake, it fails to compile.

This is frustrating.

Very weird.

Could you grab a copy of the working build folder and a copy of the non-working build folder, then diff their contents? (like the Makefiles)

I can imagine. Unfortunately I don't see anything really suspicious in the qmake log. Very odd indeed.

J.Hilk

A general update.

Over the weekend, I updated QTC and Qt on my private iMac to the latest versions as well.
The issue with QQuickWidgets is reproducible with that installation of Qt as well as with the one on my MacBook, this seems to be a general problem?

I took my own advice and contacted Customer Support as well, hopefully Irfan can shed some light on the issue ;-)

Well the diff output is not very large, everything is missing accept the make file, and the difference between those two is:

@J.Hilk well I guess it‘s now officially a bug:
https://bugreports.qt.io/browse/QTBUG-72641

I‘ll keep this topic open until the bugreport is closed.

Thanks all for the help in trying to figure it out!

kshegunov

Yep, thanks for linking it here as well.

PS.
You changed names in the mean time ... very slick ... :)

J.Hilk

And rejected as not reproducible, seems like only my 3 macs are effected.

I give up and stick with 5.11 for the foreseeable future.

Kalileo

I posted a workaround at the bug report QTBUG-72641:

clean the build folder, especially delete ui_mainwindow.h.
In Forms/mainwindow.ui change

<header>QtQuickWidgets/QQuickWidget</header>

to

<header>QQuickWidget</header>

and rebuild.

So go ahead and use Qt 5.12 :)

J.Hilk

hey @Kalileo thank you very much.

It does require an external text editor, because you're not allowed to edit the ui file in xml format from QtC 🙄, but it's a 1 time modefication of the file and it will work for any and all rebuilds.

Very nice!

Kalileo

@J.Hilk

You can also do it within QtCreator:

right click on "mainwindow.ui"
select "Open With" and then "Plain Text Editor"

J.Hilk

A quick and final update:

https://bugreports.qt.io/browse/QTBUG-72641
The topic was reopened - in no small part due to @Kalileo I believe ;-) - and the error seems to be found and fixed.

The fixed version seems to be the upcoming 5.12.1 and onwards.

Thanks everyone for the interest and help in the issue.
