It's not misleading when it is a hog fattened way past market. 90% of the embedded systems I encounter have no GPU so the driver issue is irrelevant. You get rid of all needless things to improve battery life. Claiming an i.MX6 which most certainly must need grid power or batteries the size

Re: [Interest] [Qt3D] Mixing C++ and QML

Hi, you've hit one of the issues we did with exposing C++ and QML APIs. Namely, QQmlListProperty. This thing should ideally never have existed and instead support for properties of collections should have been added to QObject and the metaobject system. To avoid pulling in a QtQml

Re: [Interest] [Qt3D] Mixing C++ and QML

You can create your own MyQmlEntity class and expose a method that call it: class MyQMlEntity : public QEntity { Q_OBJECT Q_PROPERTY(VariantList components READ get_components WRITE set_components NOTIFY componentsChanged) Q_INVOKABLE void add(QObject* obj) {

Re: [Interest] [Qt3D] Mixing C++ and QML

The issue is that QEntity doesn't reflect directly the qml type Entity, this is the same for many Qt3D classes. Here is the declaration of QEntity from qentity.h class QT3DCORESHARED_EXPORT QEntity : public QNode { Q_OBJECT public: explicit QEntity(QNode *parent = nullptr);

Because I'm the one who gets called in to sweep up the train wreck. I work in the medical and industrial device world where QML is __NEVER__ a good choice, let alone a correct choice, but, script kiddies are cheap. When you are called in to sweep it up, the client never wants to hear they have

Laszlo, 1) It's QML. Massive stinky pig which is __ALWAYS__ the wrong choice for any project. 2) EGLFS is how we got here. The Wiki instructions are pure excrement for anything more complex than "Hello World." But that's fine because the bug report for the Wiki instructions has been

[Interest] QPainter overlapping lines display problem.

Hello developpers ! I'am trying to draw multiple lines with a width of 1px (my pen is fully opaque), some of them are sitting on top of each other on some segments. The default display at scale 1 is fine/uniform. When I zoom out, lines become less than 1px on screen and they start to appear with
