Qt Contribution

@Engelard there's no direct integration, so yes, you've to file things anew.

@xxuan You could also ask on Qt Developers mailing list where you will find actual Qt developers. This forum is for Qt users.

@IDontKnowHowToCode
PyQt is produced by Riverbank Computing. If you would like to see them implement something in PyQt which would help you debug you can ask them. Or this might be a general issue in Python code which calls C libraries.

I think this is a great idea. It would be great to have more control over the serialization of JSON data. It would make it easier to customize the output and make sure that the data is properly formatted. It would also make it easier to debug any issues that may arise. I think this would be a great addition to the Qt library.

My steps:

cd /home/user8937666/QtProj/key/ ssh-keygen -t ed25519 -f /home/user8937666/QtProj/key/my_qt_ssh_key -N "" -C myKeyForQt <<< $'\ny' >/dev/null 2>&1 ssh -vvv -p 29418 user8937666@codereview.qt-project.org -i /home/a/QtProj/key/my_qt_ssh_key

Now works (thanks). But with default RSA (without -t ed25519 ) it doesn't work (error "no mutual signature algorithm"), why?

Hello. I'm using a different account now.

What happened was I subscribed to the mailing list and sent the message, but I got a reply saying that I can't send messages to the mailing list because I'm not a Qt developer. I don't know why but after that I just gave up on the idea and tried to create an external binding, and I completely forgot about this untill now. It's probably a good thing though, because I've gained a lot more experience in C++ since then and I think I wouldn't have been able to contribute anything without it.

I've created a gerrit account by following the "Contributing to Qt" wiki, and I'm going to try to send a message again. Just wanted to appologize for forgetting about the thread half-way through the discussion. I'll mark it as solved.

EDIT: I can't mark it as solved on this account, but I'll sign in later today and do that.

Hi, and welcome!

@Xarzu said in Typo found online:

Hello friends. I want to help. I found a typo online (https://wiki.qt.io/Building_Qt_5_from_Git#Getting_the_source_code) under the caption "Cloning specific Qt submodule", the first word "Ypu" should be "You". I only want to help.

Thanks for reporting this. I have fixed it.

In the future, you can edit Wiki articles yourself. Just log in with your Qt Account.

@jsulm said in Typo found online:

You should file a bug report here: https://bugreports.qt.io/secure/Dashboard.jspa
This is user forum without many developers working on Qt/documentation.

This is true for articles at https://doc.qt.io/

For future reference, I am going to answer my own question: pyside6-lupdate is the same thing as the main Qt Linguist lupdate, so its source is located at https://code.qt.io/cgit/qt/qttools.git, and more specifically https://code.qt.io/cgit/qt/qttools.git/tree/src/linguist/lupdate . This appears to be based on the original "pylupdate" code, though it's been refactored a fair bit.

@SGaist said in How is QSqlTableModel ok?:

the model shall be deleted before the QCoreApplication and thus its private part as well and thus the db object.

Not necessarily... for example

#include <QApplication> #include <QTableView> #include <QSqlTableModel> #include <memory> int main(int argc, char *argv[]) { std::unique_ptr<QSqlTableModel> model; QApplication a(argc, argv); QSqlDatabase db = QSqlDatabase::addDatabase(QStringLiteral("QSQLITE")); db.setDatabaseName(QStringLiteral("/path/to/mydb.sqlite")); Q_ASSUME(db.open()); model = std::make_unique<QSqlTableModel>(); model->setTable(QStringLiteral("MyTable")); Q_ASSUME(model->select()); QTableView tableView; tableView.setModel(model.get()); tableView.show(); return a.exec(); }

Now we can agree that, in practice, it seldom happens but I still don't understand if the design choice opens up the problem without safeguards or warnings or if I'm just missing something that makes it ok.

Hi,

@davecotter said in How to have my .pro depend on qt.pro ?:

Third: what's the recommendation about -developer-build ? I understand that regardless of "-prefix" setting, it will build within the Src tree, which is exactly what you do NOT want assuming you're using Git to submit your changes?

Out of source builds are the key.

@davecotter said in How to have my .pro depend on qt.pro ?:

Fourth: the .pro.user file is created within the Src tree, which is not okay with Git. How do i force Qt Creator to put that somewhere else?

Usually ignored by the .gitignore file.

@davecotter said in How to have my .pro depend on qt.pro ?:

Fifth: assuming all the above gets straightened out, when i build in Qt Creator, note i do not do "make install". does that happen automatically? do i need a "post build step" on the "qtmultimedia/src" project to stage that into place for debug builds?

You need a custom build step indeed.

AFAIK, it should not.

Did you try to do a clean rebuild ?

the answer was i was building the wrong branch. switched to 5.15.2 and all is well.

yeah, kay. thanks for bearing with me, i've never done this before!

:D

i think you should move steps 6 and 7 from the top, and integrate them into the bottom, or really just make it one list, no need for separate sections

yes, i upgraded to xcode 10 and it started working
