Qt 6

Hi and welcome to devnet,

That is a question that cannot be easily answered as this is a pretty big project.

If you want to help answer it, the best would be to at least prepare a simple set of instructions for people to get that application up and running. As well as check where the menu is created and pinpoint that part, etc.

Hi,

Start the application from the command line with the QT_DEBUG_PLUGINS environment variable set to 1 to see what is happening with the plugins.

One thing that you can also check: are you using the same Qt version that was used to build Qt Creator ?

@ofmrew said in Undefined reference to constructor:

I checked the values at the break point and the looked OK.

No idea what this means, but never mind.

The question is how do I solve the free function problem?

Define them as member functions. If you do not understand the difference between class member functions and free functions you need to understand that from a C++ book/tutorial, else you won't get far in C++.

Great, thank you! Here's the link to the documentation for anyone who is curious.

Hi,

Can you provide a minimal compilable example that shows this behaviour ?

Thanks @JonB - I also just discovered the notes at https://www.qt.io/blog/qt-extras-modules-in-qt-6.

Using Qt 6.3.0, I've enabled the private headers ( QT += core-private ) and with a slight re-write, the permission checks and requests seem to be working fine.

Thank you so much for your precious help.
Very clear explanation.
Also, It worked correctly.

@J-Hilk Thank you so much.
It worked.

Why should a column with a width of 0 be shown?
Also you should not set a column width of 0 by yourself - use hide/show functions instead.

Same here with QListWidget..
I create a ticket ! https://bugreports.qt.io/browse/QTBUG-103855

this is now marked as a bug:
https://bugreports.qt.io/browse/QTBUG-103811

Having filed this as a bug here: https://bugreports.qt.io/browse/QTBUG-103594, @Croitor-Alexandru responded (to the bug) with some useful comments about structuring a project. As it's relevant, I've taken the liberty of copying a snippet here:

We recommend placing each qt_add_qml_module call in its own $project_src_dir/CommonAnimals/CMakeLists.txt, and add that cmakelists.txt file with add_subdirectory(CommonAnimals). Then the built module is placed in $project_build_dir/CommonAnimals/qmldir and the default qml engine import path is able to find the qml module.

To date I haven't encountered any issues with import in QML where all files are in the project source folder and organisation of them is handled in Qt Creator, which generates a virtual folder structure based on QML modules defined in CMake. However I'll file this advice away in case I need to change things in future.

@Franz-Hirschbeck said in QSharedPointer<const QObject> results in compiler errors when used in metatyping (Q_DECLARE_METATYPE):

Is there something wrong with my setup?

Yes, but not syntax-wise.

Am I the only one using QSharedPointer to const object with signal/slot?

QSharedPointer doesn't really make any sense here, as you're reference counting (externally) an object, that is never supposed to be detached (copied). What should be the purpose of having a QSharedPointer instead of say const QObject *?

Edit: Well, I'd missed that this is an old-ish topic when I replied

Should have informed about the focusPolicy:

@CharlesHuff
oops...

I noticed another line with target_link_libraries and moved the above two lines to just below that! now it links just fine. I am finally on the path....
