Id and properties not found problem

olivierguzziIDEOL

Dear all,

I'm actually experimenting Qt/QML with RTMaps (a real time graphical programming tool).

I faced with an issue a lot of time, i could turn around but i'm really asking why when I use this component (the code is just below) in my main .qml,
the property defined using the ParamsPanel's id azert raises an error: azert id cannot be found but it is.
I had the issue with the Rectangle called container.

import QtQuick 2.5
import QtQuick.Controls 1.0 /** Tab import **/

/** #### SettingsTab component ### **/
Tab {
    id : root
    title : "Settings"
    anchors.fill: parent

    /** ### Properties ### **/
    /** ### INPUTS ### **/
    property string ipIn: ""
    property int portIn: 0
    property int interPingIn: 0
    property int packetCountIn: 0
    /** ### OUTPUTS ### **/
    property string ipOut: azert.ipOut
    property int portOut: azert.portOut
    property int interPingOut: azert.interPingOut
    property int packetCountOut: azert.packetCountOut

    /** #### SubComponents ### **/
    Rectangle {
        id : container
        anchors.fill: parent
        color: "#00000000"

        /** #### SubComponents [LEVEL 2] ### **/
        ParamsPanel {

            x: 282
            y: 243
            id:azert     
            anchors.bottom: parent.bottom
            anchors.bottomMargin: 127
            anchors.right: parent.right
            anchors.rightMargin: 30

            /** ### INPUT PROPERTIES SET ### */
            ipIn: root.ipIn
            portIn: root.portIn
            interPingIn: root.interPingIn
            packetCountIn: root.packetCountIn
        }
    }
}

The error:

SettingsTab.qml:40: ReferenceError: azert is not defined
SettingsTab.qml:39: ReferenceError: azert is not defined
SettingsTab.qml:38: ReferenceError: azert is not defined
SettingsTab.qml:37: ReferenceError: azert is not defined

If someone see where i am wrong, please help me ! :)

Thanks for your help,
Olivier

@olivierguzziIDEOL said in Id and properties not found problem:

property string ipOut: azert.ipOut

probably azert isn't created at the time the ipOut string refers to azert
try something like this:

property string ipOut: azert? azert.ipOut : ""

I tried but it didn't work :/
I already tried to put the property declaration under the azert (ParamsPanel) declaration but it didn't work too.

The id is declared just after its use.

It seems like my component's id isn't set to what i wrote after id:, is it possible ? When i launch my console, the display is nice but i can't access ipOut from my program.
I have a big problem with id.

@olivierguzziIDEOL sorry - have no idea. never did QtQuickControls 1.0 apps - started Qt development with QtQuickControls2

@olivierguzziIDEOL You can define Component.onCompleted for each item where you check if azert is available.

Component.onCompleted: {
console.log("Tab(/Rectangle/ParamsPanel) is now completed")
console.log(azert)
}

It should be at least in ParamPanel's onCompleted. There you should be able to bind the Tab's properties dynamically.
