QML Key Event Problem

Alien

Hello,

I've implemented small application with two event handling on keyboard keys to capture press and release event I don't know why press and release event com after each other while I hold the press?

import QtQuick 2.10
import QtQuick.Window 2.10

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


    Item {

        focus: true
        Keys.onPressed: {
            if (event.key == Qt.Key_Left)
            {
                console.log("move left pressed");
                event.accepted = true;
            }
        }
        Keys.onReleased: {

            if (event.key == Qt.Key_Left)
            {
                console.log("move left released");
                event.accepted = true;
            }
        }
    }
}

While I press left arrow the output is:

qml: move left pressed
qml: move left released
qml: move left pressed
qml: move left released
qml: move left pressed
qml: move left released
qml: move left pressed
qml: move left released
qml: move left pressed
qml: move left released
qml: move left pressed
qml: move left released
qml: move left pressed
qml: move left released
qml: move left pressed
qml: move left released
qml: move left pressed
qml: move left released

Best regards,

Use the event's isAutoRepeat property to check if it's an auto-repetition:

        Keys.onPressed: {
            if (event.key === Qt.Key_Left && !event.isAutoRepeat)
            {
                console.log("move left pressed");
                event.accepted = true;
            }
        }
        Keys.onReleased: {

            if (event.key === Qt.Key_Left  && !event.isAutoRepeat)
            {
                console.log("move left released");
                event.accepted = true;
            }
        }
