How I fixed wrong colors in my QML app on Android
I removed android:theme from AndroidManifest.xml:
<activity android:name="net.geographx.MainActivity"
android:configChanges="orientation|uiMode|screenLayout|screenSize|smallestScreenSize|layoutDirection|locale|fontScale|keyboard|keyboardHidden|navigation|mcc|mnc|density"
android:label="@string/app_name"
android:theme="@style/AppTheme"
android:launchMode="singleTask"
android:screenOrientation="portrait"
android:exported="true">
<!-- Splash screen -->
<meta-data android:name="android.app.splash_screen_drawable" android:resource="@drawable/splash"/>

Make QML menu width fit the content
Found an implementation here and added two pixels:
import QtQuick
import QtQuick.Controls
import QtQuick.Layouts
Menu {
width: {
var result = 0;
var padding = 0;
for (var i = 0; i < count; ++i) {
var item = itemAt(i);
result = Math.max(item.contentItem.implicitWidth, result);
padding = Math.max(item.padding, padding);
}
// It looks like two pixels are missing to remove the ellipsis.
// My first idea was that it is leftInset + rightInset, but it does not work.
var missing = 2;
return result + padding * 2 + missing;
}
}

Implicitly-declared move assignment operator
If no user-defined move assignment operators are provided for a class type, and all of the following is true:
- there are no user-declared copy constructors;
- there are no user-declared move constructors;
- there are no user-declared copy assignment operators;
- there is no user-declared destructor,
