As I understand there is no way to draw dashed line in Qt Quick Scene Graph
so I decided to create shader material to do this.
I'm trying to apply this approach http://korkd.com/2012/02/15/dashed-lines/
to this example
http://doc.qt.io/qt-5/qtquick-scenegraph-simplematerial-example.html.

Hello everybody. I have a project where a lot of objects are painted on the
screen whenever the user interacts with the app (pan, zoom, move) I would
be really grateful to you if you could answer a few questions regarding the
internals of Qt Quick Scene Graph:
1. Imagine that I add 1000 nodes
st I was thinking about deriving classes like Triangle from QQuickItem
and then reparenting them to the View but the direct creation of
QSGGeometryNodes seems to me to be less memory requiring approach.

? Is allocating 1000 QSGNodes in View significantly faster than
creating 1000 QQuickItems with the same painting logic and then setting its
visual parent to View?
Thank you

Sorry for so much questions, but my project has to display and process a
lot of items on the screen and it has to work good on mobile platforms.
Thank you very much for all your advices and suggestions.

Hi,
I'm trying to use Qt Sensors but it doesn't work on my Nexus 7 (2nd gen).
First I used QTapSensor from C++ but QTapSensor::reading() returns null and
QTapSensor::connectToBackend() returns false, although I call
setReturnDoubleTapEvents(true) and start() before using sensor.
Second I used
Hello,
I use QtQuickControls 2 together with QQuickItem-derived class in my app.
After I set AA_EnableHighDpiScaling attribute and all QQuickControls 2
components look correctly on my smartphone but object of my custom class is
scaled incorrectly. Here is the app without HighDpi scaling with
