[Interest] Awkward problem on iOS app deploy - qtquickcontrols plugin not found
Hi, I have a project with the following structure: shared/shared.pri // please note that shared is a level below project dir project/app/app.pro project/common/common.pri project/plugin/plugin.pro shared is code and resources shared among different projects. Is composed mostly from qml files and images. shared/*.h shared/*.cpp shared/qml.qrc shared/qml/*.qml // qml files are prefixed with /qml/ shared/icons/*.png // icon files are prefixed with /icons/ common is code, qml and images shared among app and plugin common/*.h common/*.cpp common/qml.qrc common/qml/*.qml // qml files are prefixed with /qml/ common/icons/*.png // icon files are prefixed with /icons/ app.pri includes common and shared: include(../../shared/shared.pri) include(../common/common.pri) Common has the main.qml and loads every other qml The strange part is: this project architecture works on desktop but when I use it on iOS it fails to load QtQuickControls plugin (module QtQuick.Controls plugin qtquickcontrolsplugin not found). However, if I keep the shared as it is and place common inside app dir and create a qml.qrc file with the qml files referenced from within app/common/qml, with the same prefix /qml/, it works. Is this a known problem? I’m using Qt 5.4.1 Thanks, Regards, Nuno___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Re: [Interest] How to share a native OpenGL context with Qt?
Hi, Il 17/06/2015 17:54, Marc Gilleron ha scritto: Our context is created in a custom way, nothing to do with Qt in the first place. We made a test with a QML window and another non-Qt window where we used to render OpenGL, and it doesn't works because of resource clashes. So we need to share. Is there a way to do this with Qt by setting the |Qt::AA_ShareOpenGLContexts |flag? I didn't found any global context to call share on it in the public API... I've added a getter for that global context in 5.5: http://doc-snapshots.qt.io/qt5-5.5/qopenglcontext.html#globalShareContext If you peek at the implementation you can actually also grab it on = 5.4 by using some private APIs. Note: I know there are canonical ways to draw OpenGL stuff in Qt, however, none of them currently suits our needs in terms of existing codebase and time. We want to be able to draw from our own loop, in our own surface, which is neither inside a paintGL()/Qt call, nor in another thread. Now from your email I'm not 100% sure of what you need to achieve. Do you want to draw QML content on top of some other OpenGL content, and do that in a non-Qt window / GL context? There's QQuickRenderControl for that.

Loading *any* website is slow but it is particularly noticeable with Google Maps. It can take more than a minute to render the initial map and then zooming in first shows just a scaled and pixelated version of the map and then it can several minutes for the details to be rendered properly. Also, switching from map to Earth/Satellite view seems to take forever too. What could be causing this incredible slowness? It's not the network itself as the same sites load instantaneously in other browsers like Chrome and Firefox on the same machine and there is no proxy involved. Given that the primary use case I had intended for the Qt browser implementation is Google Maps, this is all very worrying!

QVectorTypedData was never public API and you could never have accessed it in Qt 4 if you started from a QVector, short of an ugly hack. If you're using QVector, you'll have to stop doing whatever hack you were doing and rewrite your code. If you were using QVectorTypedData outside of QVector, you can copy the definition from Qt 4 and continue using it.
