iOS only: Cannot have Quick Control 1 and Controls 2 at same time

XMLWordPrintable

    • iOS/tvOS/watchOS
    • 826b09f0c507fe5321a8534054a4f0b7bdd2699b (qt/qtbase/5.12)

      Sample code:

      import QtQuick 2.10
import QtQuick.Window 2.10
import QtQuick.Controls 1.3 as Controls1
import QtQuick.Controls 2.1

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
}

      This is kind of a dealbreaker as it for example breaks the FileDialog component that internally still uses Controls 1.

      On 5.11.2 everything works.

      On 5.12.0 rc1 I get:
      qrc:/main.qml:4 module "QtQuick.Controls" version 2.1 is not installed

      I wonder what changed between those versions? Somehow in creating the app bundle maybe or otherwise in deploying the qml resources or namespaces? Although everything should be in the library plugins, I don't know enough about the internals to understand this myself.

      Thank you @richard for helping me to reproduce this.

      Output of qmlimportscanner shows both:

      In the LIBS I see both -lqtquickcontrolsplugin and -lqtquickcontrols2plugin ..
