[Interest] How to set a non-global context property for a single QQmlComponent?
Hello! Surely there must be a way to set a context property on a single component without having to set it globally on the entire QQmlEngine? Indeed, the QQmlContext documentation is silent on this point. Help?? ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest

Shoot, you know at first pass it looks like that will work. Wow. I wonder if this is possible to do with QQuickWidget? Or if not how to show a component into a QWidget without QQuickWidget? > On Jul 17, 2019, at 1:35 AM, Sérgio Martins wrote: > > On 2019-07-17 10:15, Patrick Stinson wrote: >> Hello! >> Surely there must be a way to set a context property on a single >> component without having to set it globally on the entire QQmlEngine? >> Indeed, the QQmlContext documentation is silent on this point. >> Help?? > > Hi, > > > You can create a child QQmlContext via this constructor [1], and then pass it > to QQmlComponent::create() > > > > [1] - https://doc.qt.io/qt-5/qqmlcontext.html#QQmlContext-1 > > Regards, > -- > Sérgio Martins | sergio.mart...@kdab.com | Senior Software Engineer > Klarälvdalens Datakonsult AB, a KDAB Group company > Tel: Sweden (HQ) +46-563-540090, USA +1-866-777-KDAB(5322) > KDAB - The Qt, C++ and OpenGL Experts ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest

Is there any way other than QQuickWidget to show a Qml Component in a QWidget? > On Jul 17, 2019, at 2:14 AM, Sérgio Martins wrote: > > On 2019-07-17 10:58, Patrick Stinson wrote: >> Shoot, you know at first pass it looks like that will work.

A colleague of mine offered a workaround: QQmlContext *subContext = QQmlEngine::contextForObject(myQuickWidget.rootObject()) That should be a subContext already, different from the engine->rootContext() Regards, Sergio On Jul 17, 2019, at 1:35 AM, Sérgio Martins wrote: On 2019-07-17 10:15, Patrick Stinson wrote: Hello!

Re: [Interest] How to set a non-global context property for a single QQmlComponent?
Right, I did try that one but if I remember right I got an error setting the context property, or that it was the same as the engine root context. > On Jul 17, 2019, at 3:37 AM, Sérgio Martins wrote: > >> On 2019-07-17 10:58, Patrick Stinson wrote: >> Shoot, you know at first pass it looks like that will work.

[Interest] android: package commandline application in APK
Hello, I want to include some console binary file into my APK and launch it when my app runs. Is it possible? ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
Re: [Interest] android: package commandline application in APK
Well, it seems i've found a solution:
1. Deploy via assets:
.pro file:
my_bin.path = /assets
my_bin.files += /path/to/bin
INSTALLS += my_bin
2. At the first run, copy the file and set permissions:
QFile file("assets:/mybin");
auto dstFilePath = "./mybin";
if (file.exists() && !QFile::exists(dstFilePath))
{
file.copy(dstFilePath);
QFile::setPermissions(dstFilePath,
QFile::ExeOwner | QFile::ReadOwner |
QFile::ExeUser | QFile::ReadUser |
QFile::ExeGroup | QFile::ReadGroup |
QFile::ExeOther | QFile::ReadOther);
}
