I would like to add, that I'm using this code to bind
EventHandler<InputEvent>:
getScene().setOnTouchPressed(this);
getScene().setOnTouchReleased(this);
Then this method is called:
@Override
public void handle(InputEvent e) {
handleEvent(e);
}
private void handleEvent(InputEvent e) {.}
Touch point are iterated (for logging) this way:
if (e instanceof TouchEvent) {
TouchEvent te = ((TouchEvent) e);
INPUT_EVENTS_LOGGER.debug("- touchEvent - setID = " + te.getEventSetId() +
", touchPoint count = " + te.getTouchCount() + ", point = [" +
te.getTouchPoint().getScreenX() + ", " + te.getTouchPoint().getScreenY() +
"]");
for (TouchPoint tp : te.getTouchPoints()) {
INPUT_EVENTS_LOGGER.debug("--> point: [" + tp.getScreenX() + ", " +
tp.getScreenY() + "], state = " + tp.getState().name());
}
}
Is it the right way how to bind Touch events listener?
Is there any possibility how to detech touch point in "lower API"?
Thanks
David

Subject: Multiple vertical touch events at once - OpenJDK 11.0.2
Hello,
several times a day I observe multiple touch events at once, whereas I touch
only with one finger to one place.
These touches are always vertical = almost the same X coordination, but the
large area in Y coordination. I'm using resolution 1920x1080.
I've tried 2 different touch monitors, but the same behaviour - both iiyama
T2235MSC-B1. I've written C++ touch application to check my touch screen,
but it's perfectly okay, no this behaviour in C++. Only in Java FX. I'm
using OpenJDK 11.0.2 and Windows 10.
Every time this happens only when I touch the screen. Is there any cache for
touch events in JavaFX, which is not properly cleaned? Have you observed
this as well? What can I do? This is a showstopper for my whole app in
production.
Problem starts at
