Popup in ListModel

mamoud

Hello,

I have a ListModel as shown below:

List.qml

ListModel {
    property string parentMenu

    property variant sens: dids.sens //reading data

    property string title: " LIST "
    property bool showFunctions: true
    property variant didsReadOnce: [
        "sens",
    ]



    ListElement {
        type: "value"
        label: "sens"
        func1value: -128
        func1text: "DEFAULT"
        func3value: -1
        func3text: "!minus"
        func4value: 1
        func4text: "!plus"
        target: "dids.sens"
    }

in this code i set values manually by buttons for + and -, but i want to popup a window when the value reaches 9 for example.

I tried to add popup but it does not work when I put it in the ListModel like this:

ListModel {
//code

Popup{

///code
}

}

How can I popup a window in this case??

Place it outside of your ListModel. You can always access it by id.

Hi, thanks, but when I try to put a popup outside the ListModel I get a syntax error

ListModel{
// code
}

Popub{
//code
}

Popub{

Typo :-)

What syntax error?

mamoud

@sierdzio

Yeah, I mean i typed wrong, but when i write Popup, it still gives syntax error

also for example if I created a Rectangle or Item, and put the Popup outside them it did not recognize the Popup

what error? I you want to get help, paste the exact error that QML engine prints. Otherwise I can only guess.

mamoud

@sierdzio

it just says Syntax error, when I run the program. showing Popup with arrow pointing up and says Syntax error.

When i put the Popup inside ListModel, it gives no errors

sierdzio

Eh, ok. Does your QML use Window / ApplicationWindow as it's root element? Do you import Controls 2 module, where Popup is located?

mamoud

@sierdzio

Yeah I imported Control 2 like this:

import QtQuick.Controls 2.4
and my Popup located in a different folder but i imported it also

sierdzio

Ah wait, of course. Your List.qml contains a ListModel element, which you probably assign somewhere else. That is where the popup should be: in the view component, not in the model!

mamoud

@sierdzio
so should i create the popup object in ListElemnt

sierdzio

No! ListElements are static and cannot have any property changes.

Popup belongs into GUI code, not to model and its data. Somewhere in your code you do have ListView, right? That's where your popup needs to be. Or, as another convention has it, you can place it in your main.qml, as a direct child of your Window.

mamoud

@sierdzio

yeah right, I have a qml file called ItemView.qml

in this file there is an object called ListView, should I put the popup inside this object ListView like this:

ListView{

popup{

}

}

sierdzio

Rather somewhere beside it

ListView {}
Popup {}

@sierdzio
Thank you for your help, but i still have the same problem :(
when i put popup outside ListModel , i get syntax error

sierdzio

Do you include the module in qmake?

QT += quickcontrols2

Hi, I tried different ways to solve this, but unfortunately did not work. Is there anyway instead of popups to show that, the value of "Senstivity" exceeded a specific value
