property name <<speed>> invalid. (M16)

Sadok_J

Hi! I'm trying to call 3 files in my dashboard.qml file : speed, RPM and EngCoolTemp. The RPM and EngCoolTemp called correctly with no error but when i call speed it gives me the "property name <<speed>> invalid. (M16)" error; here's the code:

import QtQuick 6.2
import QtQuick.Controls 6.2

Item {
id: id_dashboard

// To create data for demonstration purposes
property int countSpeed: 0
property int countRPM: 0
property int countEngCoolTemp: 0

Timer {
    id: id_timer
    repeat: true
    interval: 1000
    running: true

    onTriggered: {
        updateSpeed();
        updateEngCoolTemp();
        updateRPM();
    }
}

// Speed Gauge
Rectangle {
    id: id_speedArea

    anchors {
        horizontalCenter: parent.horizontalCenter
    }
    width: parent.width * 0.4
    height: width
    color: "black"
    radius: width / 2
    z: 1

    speed {
        id: id_speed
        anchors.fill: id_speedArea
        anchors.margins: id_speedArea.width * 0.025
    }
}

// RPM Gauge
Rectangle {
    id: id_RPMArea

    anchors {
        bottom: id_speedArea.bottom
    }
    x: parent.width / 20
    width: parent.width * 0.35
    height: width
    color: "black"
    radius: width / 2

    RPM {
        id: id_RPM
        anchors.fill: id_RPMArea
        anchors.margins: id_RPMArea.width * 0.025
    }
}

// Engine Coolant Temperature Gauge
Rectangle {
    id: id_EngCoolTempArea

    anchors {
        bottom: id_speedArea.bottom
    }
    x: parent.width - parent.width / 2.5
    width: parent.width * 0.35
    height: width
    color: "black"
    radius: width / 2

    EngCoolTemp {
        id: id_EngCoolTemp
        anchors.fill: id_EngCoolTempArea
        anchors.margins: id_EngCoolTempArea.width * 0.025
    }
}

// Divider
Rectangle {
    id: id_divider

    anchors {
        bottom: id_speedArea.bottom
        left: id_RPMArea.horizontalCenter
        right: id_EngCoolTempArea.horizontalCenter
    }
    height: id_RPMArea.width / 2
    color: "black"
    z: -1
}

function updateSpeed() {
    countSpeed++;
    if (countSpeed % 2 === 0) {
        id_speed.value = 0;
    } else {
        id_speed.value = 280;
    }
}

function updateEngCoolTemp() {
    countEngCoolTemp++;
    if (countEngCoolTemp % 3 === 0) {
        if (id_EngCoolTemp.value === 0) {
            id_EngCoolTemp.value = 120;
        } else {
            id_EngCoolTemp.value = 50;
        }
    }
}

function updateRPM() {
    countRPM++;
    if (countRPM % 2 === 0) {
        if (id_RPM.value === 0) {
            id_RPM.value = 7000;
        } else {
            id_RPM.value = 0;
        }
    }
}

}
how can i solve this problem.and thanks!

speed {} - Component should start with Uppercase letters. Just see this.

Sadok_J

if i write it with an uppercase S, it gives me this error : unknown component.(M300)

Presumably, your 'Speed.qml' is in another directory, I don't see any import statement heading your file.
