[Interest] Using QtQuickControls 2 within a static build of Qt 5.7

[Mitch Curtis]

Do you have any issues creating a standard Qt Quick Controls 2 application against a static Qt? I just tried with a very basic application and it worked without issues (Ubuntu 16.04, Qt 5.7).

Hi,

I’m not being able to use QtQuickControls 2 in a static build of Qt. In order to register the QtQuick stuff within Qt 5.6 I had to manually link with the plugin lib and initialise the plugins manually. I think this was because of a bug: https://bugreports.qt.io/browse/QTBUG-35754

Apparently the bug was fixed and I should be able to use normally however there are no instructions for that so I’m using same registering process I had for QtQuickControls with some nuances and now I have this:

Q_IMPORT_PLUGIN(QtQuickControls1Plugin)
Q_IMPORT_PLUGIN(QtQuickControls2Plugin)

…

qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickControls1Plugin().instance())->registerTypes("QtQuick.Controls");
qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickControls1Plugin().instance())->registerTypes("QtQuick.Controls.Styles");
qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickControls1Plugin().instance())->registerTypes("QtQuick.Controls.Private");
qobject_cast<QQmlExtensionPlugin*>(qt_static_plugin_QtQuickControls2Plugin().instance())->registerTypes("QtQuick.Controls”);

However, it complains about not knowing nothing about, e.g. Slider. It also gives an error: qmlRegisterType requires absolute URLs. I have digged the source down and the qmlRegisterType functions has the following validation:

if (url.isRelative()) {
          // User input check must go here, because QQmlPrivate::qmlregister is also used internally for composite types
          qWarning("qmlRegisterType requires absolute URLs.");
          return 0;
}

So I supposed the types end up not being registered anyway. By the time the plugin is registered, the following url is being passed to the first registration: "qrc/ApplicationWindow.qml”

What am I missing here?

Thx!

Nuno
