Re: [Interest] Qt 6 Universal binaries for Mac OS?
Hi, Seems like the doc snapshots haven't been indexed by search engines yet (from my results at least). See https://doc-snapshots.qt.io/qt6-6.2/macos.html#architectures You can specify the relevant options in Creator's Project pane for either build system.

[Interest] Qt 6 Universal binaries for Mac OS?
Hello all. We have been waiting for Qt 6.2 for universal binary support. I have 6.2 RC and have our app building and running fine in Creator (for Intel on an Intel machine, Big Sur, Xcode 12). Does anyone know how to then create the universal binaries? I have found documentation on building Qt for both architectures, but that's irrelevant as we use the pre-compiled Qt downloaded through the maintenance tool. Our current process has been to dev/build the app in Creator (we do not use Xcode, find Creator much easier and more user friendly). Once done, I copy the bundle somewhere, run macdeployqt on it, sign it, then notarize it. Of course there's some details in between but that's essentially it, I have a pkg to distribute. I'm not seeing in Creator now how to create a universal binary, or finding any docs. Thanks! -- Wes Krasko www.worldwidewes.com www.kraskofamily.com "Stay away from negative people.

Re: [Interest] [External]Re: Proxied view not updating live when source model does
Thanks for the response, but no, that’s not it. Modifying my baseModel’s
setData from
emit dataChanged(index, index, QVector() << role);
to
emit dataChanged(index, index, QVector() << role << Qt::DisplayRole);
changes nothing in the behavior…

You emit dataChanged with the given role (which is Qt::EditRole), but not for
Qt::DisplayRole. Is it that?

proxyIndex.column());
}
return QModelIndex();
}
I load up my source model with some data, connect the models up to their
respective views,
connect the source model to the proxy and launch the application. The original
views are
correct - the proxied rows are flipped when compared to the source model. But
then if the
user makes a change to some of the data in the source model's view, the
corresponding index
in proxy model's view is NOT updated automatically. HOWEVER, if the user then
clicks within
the proxy view, or clicks outside of my application, the proxy model will then
repaint and the
updated information is correctly shown.
I've attached a minimal example that shows the behavior. Things to note:
1. When the source model emits its dataChanged(), this seems to trigger a
dataChanged()
emission in the proxy model as well. The weird (at least to me) thing is that
both of those
signals have the SAME model index row & column numbers. I would have expected
that
when the source model emits data changed, that the proxy model would
translate the
source model's indices into the proper proxy model's indices via the
mapFromSource()
function and then emit dataChanged() with those indices. I've got debug
statements in
my example to illustrate that no dataChanged() translation is happening - if
the user
updates data in row 0 in the source model's view, the proxy model also emits
that data
changed in its row 0, but that isn't the correct row for the proxy.
2. We discovered that if we connect the proxy model's dataChanged() signal to a
custom
slot within the proxy model, and have that slot emit layoutChanged() then we
can get
the live update behavior when the source model updates. This is at line 25 of
invertrowsmodel.cpp. It's commented out initially, but if you uncomment it
and re-run
the app then proxy view does update instantly. Other similar signals would
work as well -
we just need something triggers the proxy view to refresh the data in the
proxied view,
but we don't think we should really have to do this...
3. I have a second view attached to the source model and both source model
views update
each other live - changes in one source model view are instantly updated in
the other
source model view, but not in the proxy model view without further user
interaction
(or by emitting that layoutChanged() signal)
Any thoughts as to why the proxy model isn't updating correctly?

Re: [Interest] Proxied view not updating live when source model does
> to both rowCount() and columnCount() removed those errors and now my > application runs silently. I should have explained better. It runs silently in the sense that the QAbstractItemModelTester instances aren't printing out any information any more. The broken behavior still exists where the view connected to the proxy model isn't repainting the corresponding row as the source model's data changes. Instead it is repainting the same row as the source. For example: 1. If initially populate the source model with 3 rows of data A 1 B 2 C 3 The proxied view correctly shows this data inverted: C 3 B 2 A 1 2. If I then edit cell (0,0) in the source view from 'A' to 'Z': Z 1 B 2 C 3 The proxied view doesn't update, still showing an 'A' in cell (2,0) which is supposed to map to source (0,0): C 3 B 2 A 1 3. If I then edit cell (2,0) in the source view from 'C' to 'X': Z 1 B 2 X 3 The proxy view updates to: C 3 B 2 Z 1 I still think the problem is that the dataChanged() signal that automatically gets emitted by the proxy model off from the source model's dataChanged() signal has the EXACT SAME INDEX as the source model: "baseModel::slotDataChanged: Index: (2, 0)" "invertRowsModel::slotDataChanged: Index: (2, 0)" I think the correct behavior for the proxy should be that when the source's dataChanged() signal fires, the indices in that signal should be translated through mapFromSource() to then get re-emitted from the proxy model so the attached view would then call the proxy's data() with the mapped index (in this example, when source data changes at (2,0) the proxied view should be informed that index (0,0) changed to refresh that data), but that doesn't seem to be happening automatically...

[Interest] New open source PDF support library for Qt + serveral PDF applications
Dear Qt users, I would like to inform you about my project, PDF4QT. I began this project in year 2018 as my private project, and now, I think, it is ready to be released for public beta testing. Long term goal of this project is to offer full support of PDF 2.0 specification as add-on library for Qt. I know, that Qt offers its own PDF module, but, it lacks many functionality. My project offers much more, as optional content handling, signature verification, encryption support, form filling, color management, annotations, text to speech, optimalization, sensitive content redaction, page manipulation, document merging and splitting and much more. Also, I offer several applications, which use this library, such as document viewer/editor, or command line tool. I am aware, that some other projects also implements this functionality, but they are very often using viral licenses such as GPL/AGPL. I want to be more benevolent, so PDF4QT project uses LGPL license, version 3, so it is usable also in commercial applications. I do not want to restrict people from using my library. Project can be found at this website: https://github.com/JakubMelka/PDF4QT And public beta release is available here: https://github.com/JakubMelka/PDF4QT/releases I hope you will find my 3-year work useful. PS. I will be very happy if you can contribute in a form of testing, advices, opinions... But I also want to keep control of the rights to my project, so if you want to contribute, Contributor License Agreement must be signed. Please do not respond on my email, but if you want to discuss this software, use following discussion forum: https://github.com/JakubMelka/PDF4QT/discussions Best regards Jakub Melka ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest

Ok, I think I'm now using the tester, but I'm not sure I'm using it correctly.
After I've populated my base model, assigned it as the source model to my
proxy, and then connected the models up to their respective views I call:
QAbstractItemModelTester* baseModelTester = new
QAbstractItemModelTester(mBaseModel,
QAbstractItemModelTester::FailureReportingMode::Warning,
this);
QAbstractItemModelTester* proxyModelTester = new
QAbstractItemModelTester(mInvertRowsProxy,
QAbstractItemModelTester::FailureReportingMode::Warning,
this);
And then run the rest of my application normally. On first launch after adding
those lines I saw the following statement twice in QtCreator's Application
Output pane:
qt.modeltest: FAIL! model->hasChildren(topIndex) () returned FALSE
(qabstractitemmodeltester.cpp:366)
A quick google on that pointed to the fact that I was always returning my data
size for rowCount() and 2 for columnCount() regardless of whether the parent
index was valid or not. So adding:
if(parent.isValid())
{
return 0;
}
to both rowCount() and columnCount() removed those errors and now my
application runs silently.
Am I using the model index tester correctly?
Any other ideas on how to get this working?

Hi, have you run QAbstractItemModelTester https://doc.qt.io/qt-6/qabstractitemmodeltester.html on the source model and the proxy model? It usually quickly reveals issues in the overridden methods.
