How to make qml window retain its position and size in qt5

supratik123

I am trying to make my application window which is written in qml to retain its size and position once i close the application. I came across using Settings to do the same, but my application is not able to retain its position and size after i reopen it. Below is snippet of code i have written
import QtQuick 2.12
import QtQuick.Controls 2.5
import QtQuick.Shapes 1.12
import QtQuick.Window 2.12
import QtQuick.Layouts 1.14
import Qt.labs.settings 1.0

Window {
id: rootWindow
visible: false

minimumWidth: 975//screenInfo.availableWidth * 0.7
minimumHeight: 440//screenInfo.availableHeight * 0.7
//Default Windowed size
width: 1463
height: 660

title: ""
color: "transparent"

//property bool enableCustomTitleBar: (Qt.platform.os == "windows")
property bool enableCustomTitleBar: true




property string lastSaveAsDialogTextFieldEdited: "fileNameTextField"
property bool venueNameChangedFromFileName: false
property bool venueNameEdited : false
property bool progressDialogVisibility : false
property int groupBy: 0

// Property to store window position and size
    property var windowGeometry: null
// Declare the Settings component at the root level to store window properties
    Settings {
        id: appSettings
        category: "WindowGeometry"
        property string organizationName : "abc"
        property string organizationDomain : "abc.com"
        property string windowState: 'maximized'
        property int windowLeft: 0
        property int windowTop: 0
        property int windowWidth: 1200
        property int windowHeight: 720


    }

    Component.onCompleted: {
        flags = enableCustomTitleBar ? (flags | Qt.CustomizeWindowHint | Qt.FramelessWindowHint | Qt.WindowMinimizeButtonHint) : flags


        // Load the window properties if they were previously saved
        if (appSettings.windowState === 'maximized') {
            rootWindow.visibility = Qt.WindowMaximized
        } else {
            rootWindow.x = appSettings.windowLeft
            rootWindow.y = appSettings.windowTop
            rootWindow.width = appSettings.windowWidth
            rootWindow.height = appSettings.windowHeight
        }
       

        visible = true
        
    }

onClosing :
{
console.info("Quit is invoked from means other than TitleBar ")
if (rootWindow.visibility === Qt.WindowMaximized) {

        appSettings.windowState = 'maximized'
    } else {
       
        appSettings.windowState = 'normal'
        appSettings.windowLeft = rootWindow.x
        appSettings.windowTop = rootWindow.y
        appSettings.windowWidth = rootWindow.width
        appSettings.windowHeight = rootWindow.height
    }
    if(rootWindow.visibility == Window.Minimized)
    {
        rootWindow.requestActivate()
        rootWindow.visibility = Window.Maximized
    }

where am i going wrong ?

@supratik123 The problem is that you overwrite the Settings properties with your default values.

The easiest way would be to do alias properties in your Settings object (property alias windowLeft: rootWindow.x) and set your default in your Window.

@GrecKo Thanks for your suggestion. I figured the solution out
