Language Bindings

@the_ Thank you so much for your help ^__^

I solved the problem!
Just puts the shared library into a directory named "script", inside the directory where the application binary is placed, and it's done.

Sorry for the trivial issue :(.

The module name is PyQt4 case sensitive.

Thanks for the information.
I tested on a Windows 7 virtual machine and it works. So I suppose you are right about a compatibility problem with Sierra.
I'll contact the current dev team of QtJambi.

I still got error. I tried to run this example: https://doc.qt.io/archives/qtjambi-4.5.2_01/com/trolltech/qt/qtjambi-hellowebkit-code.html

I put your file to root folder of project (same where I have pom.xml and src directory.) Is this right place? Or what would you do with the following error?

Just an update to the working state of this code. Yes it does loop as it should in both mac and windows, however, when it loops on the mac, the video scales up for some bizarre reason. I have no clue what would make it do that. Any thoughts?

Hi,

You should show the code you are using as well as the backtrace of the crash otherwise it's pretty much Crystal Ball debugging.

QWidget's documentation claims that the QWidget::paintEngine implementation may not always return a valid pointer, which is what I think causes your problem.
One solution might be to override it and provide your own QPaintDevice. On StackOverflow I found a workaround based on QtQuick instead of QtWidget, using a QQuickPaintedItem that you can use inside your QtQuick scenegraph.

Hi,

it looks like QtWebKit was superceded by QtWebEngine. Clicking together a quick sample shows the animations working for me without any more work required:

import QtQuick 2.0 import QtQuick.Window 2.0 import QtWebEngine 1.0 Window { width: 1024 height: 768 WebEngineView { anchors.fill: parent url: "http://mapshakers.com/projects/leaflet-pulse-icon/" } }

Best

@LeeDaShen
In which way, login ?
The browser dont have any login . Do you mean the user?

Dummy me...the setData signature was wrong...it has to be:

public final boolean setData(QModelIndex index, Object value, int role)

@SGaist said in QProcess event queue:

Hi,

Unless you put that in a loop, readLine will only read one line each time. One thing you can do is split the content of trace_output on the carriage return and parse each element after that.

Sry didn't get notified about your reply. I have managed to solve this using subprocess module on a different thread. Would like to see it working with QProcess too though. Did you find any bug on my code?

Hi @Exotic_Devel
The best place to follow on PySide2 seems to be https://wiki.qt.io/PySide2
It has links to all the relevant locations for more info.

Seems like it still requires manual work to build (and Qt 5.6?).
But looking at the speed of development it is close to being a good option.

@Hoyt You already have that signal in your IntValue class. So in case you are trying to access this signal from other C++ class you have the instantiated object here:

IntValue rotationAngle; engine.rootContext()->setContextProperty("rotationAngle", &rotationAngle);

Use this object and connect to its SIGNAL intValueChanged.

AFAIK, there's no support for "in-memory files" like that. Remember that QtMultimedia uses the platform's multimedia framework which don't handle Qt types. If you take for example the handling of Qt's resource system when dealing with multimedia files, a temporary file is created so that the multimedia framework can access it.

If you want something lower level to avoid the temporary file, you'll have to implement it yourself.

Hi,

This stackoverflow answer might give you some clues.

@Dante-Leoncini said in Public Functions qt++ to qml:

but now comes another error: undefined reference to `vtable for MyFunctionsProvider'

Hi,
you need to run qmake.
