Re: [Interest] QML Singleton and QTimer?

[Jérôme Godbout]

Hi,
Is your QTimer access before the QGuiApplication is created (static singleton)? 
That could explain why this complain and moving the singleton instance into the 
GuiApplcation constructor solve your problems.

What we do over here, I have a custom template method that register the 
singleton from Qml and from C++ singleton class (templated too). This keep a 
map of type and pointer to object:

typedef QMap>> SingletonMapType;
extern SingletonMapType singleton_instances_map_;

after that the C++ singleton fetch into that map and so does my Qml singleton 
register type, so I get a single instance no matter who the C++ or the Qml 
request the singleton first. It might not be ideal, but it work well. So they 
are not really a static instance but instead a version that is kept based on 
the current QQmlEngine and application. If your application only use a single 
QQmlengine (like most of them do, you can skip the first layer of the map and 
simply use the map from string to QObject. For the QString you can extract it 
from template type and T::staticMetaObject.className()

you only need a getSingleton() and a createSingleton() class to fill the 
blank. So my class are not bake with singleton, there might be an instance that 
is singleton instead (make it easier to test the class without enforcing 
singleton into it and I can still make memento and the like of those object 
without being screw to have only hard single copy.

Well, the documentation gives the example of the singleton being instantiated 
at the main.cpp:main() level.

It felt a little wrong, but I subclassed QGuiApplication, and created and 
registered the singleton there:

GuiApplication::GuiApplication(int argc, char*argv[]):

QGuiApplication::QGuiApplication(argc, argv)

{

m_hardwareInterface = new HardwareInterface;

qmlRegisterSingletonInstance("com.company", 1, 0, "HardwareInterface", 
m_hardwareInterface);

}

This seems to work, but seemed unnatural.

You can check the thread affinity of an object and the current thread that will 
display the problem you encounter. Use a queued signal into the QTimer thread 
to sent the start (it will be delayed until the thread process the event, 
hopefully you do no need precision there).

Hi,

That does sound like a bug. You should report it on https://bugreports.qt.io/

  I had a read of the article https://wiki.qt.io/Qt_for_WebAssembly


  I am hosting the example on an HTTPS server and connecting it via Chrome and

  Any suggestions?

Re: [Interest] [Development] Mac Big Sur - Qt Open-Source Support For

[Michael Jackson]

For our application we grabbed the Qt 5.15 build script that Kitware used for 
universal binary CMake and used that to build Qt 5.15.2 on our M1 mac and have 
been using that for some beta testers. So far no one has complained about M1 
specific issues. We also did *NOT* build all of Qt5, just the parts that we 
needed. Build script below.


=
#!/usr/bin/env bash

# Run this script on a macOS x86_64 host to generate Qt universal binaries.
#
# This script requires the 'makeuniversal' tool from:
#
#   https://github.com/fizzyade/makeuniversal
#
# Build it with an existing local Qt installation first.
#
# Set the PATH environment variable to contain the location of 'makeuniversal'.

[coroberti]

Dear Eike,
Thanks for your comprehensive answer.

I will try to build it from open-source 5.15 branch

Where is the link to the branch?
Thanks!

Kind regards,
Robert Iakobashvili

Re: [Interest] [Development] Mac Big Sur - Qt Open-Source Support For

[Tuukka Turunen]

Hi,

Supporting Apple silicon is something we are actively working to have in place 
for Qt 6.2 including full CI coverage etc.

To some extent things will work also with Qt 5.15 if you build yourself, but 
there are some rough edges (and Qt 5.15 is not tested for M1).

Yours,

Tuukka

Tor,

What about building Qt 5.15.X for M1 Macs?

Is there any kind of wiki resource out there?
